mm: percpu: Include smp.h in alloc_tag.h
percpu.h depends on smp.h, but doesn't include it directly because of
circular header dependency issues; percpu.h is needed in a bunch of low
level headers.
This fixes a randconfig build error on mips:
include/linux/alloc_tag.h: In function '__alloc_tag_ref_set':
include/asm-generic/percpu.h:31:40: error: implicit declaration of function 'raw_smp_processor_id' [-Werror=implicit-function-declaration]

mseal: wire up mseal syscall
Patch series "Introduce mseal", v10.
This patchset proposes a new mseal() syscall for the Linux kernel.
In a nutshell, mseal() protects the VMAs of a given virtual memory range
against modifications, such as changes to their permission bits.
Modern CPUs support memory permissions, such as the read/write (RW) and
no-execute (NX) bits. Linux has supported NX since the release of kernel
version 2.6.8 in August 2004 [1]. The memory permission feature improves
the security stance on memory corruption bugs, as an attacker cannot
simply write to arbitrary memory and point the code to it. The memory
must be marked with the X bit, or else an exception will occur.
Internally, the kernel maintains the memory permissions in a data
structure called VMA (vm_area_struct). mseal() additionally protects the
VMA itself against modifications of the selected seal type.
Memory sealing is useful to mitigate memory corruption issues where a
corrupted pointer is passed to a memory management system. For example,
such an attacker primitive can break control-flow integrity guarantees
since read-only memory that is supposed to be trusted can become writable
or .text pages can get remapped. Memory sealing can automatically be
applied by the runtime loader to seal .text and .rodata pages and
applications can additionally seal security critical data at runtime. A
similar feature already exists in the XNU kernel with the
VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall
[4]. Also, Chrome wants to adopt this feature for their CFI work [2] and
this patchset has been designed to be compatible with the Chrome use case.
Two system calls are involved in sealing the map: mmap() and mseal().
The new mseal() is an syscall on 64 bit CPU, and with following signature:
int mseal(void addr, size_t len, unsigned long flags)
addr/len: memory range.
flags: reserved.
mseal() blocks following operations for the given memory range.
1> Unmapping, moving to another location, and shrinking the size,
via munmap() and mremap(), can leave an empty space, therefore can
be replaced with a VMA with a new set of attributes.
2> Moving or expanding a different VMA into the current location,
via mremap().
3> Modifying a VMA via mmap(MAP_FIXED).
4> Size expansion, via mremap(), does not appear to pose any specific
risks to sealed VMAs. It is included anyway because the use case is
unclear. In any case, users can rely on merging to expand a sealed VMA.
5> mprotect() and pkey_mprotect().
6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous
memory, when users don't have write permission to the memory. Those
behaviors can alter region contents by discarding pages, effectively a
memset(0) for anonymous memory.
The idea that inspired this patch comes from Stephen Röttger’s work in
V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this
API.
Indeed, the Chrome browser has very specific requirements for sealing,
which are distinct from those of most applications. For example, in the
case of libc, sealing is only applied to read-only (RO) or read-execute
(RX) memory segments (such as .text and .RELRO) to prevent them from
becoming writable, the lifetime of those mappings are tied to the lifetime
of the process.
Chrome wants to seal two large address space reservations that are managed
by different allocators. The memory is mapped RW- and RWX respectively
but write access to it is restricted using pkeys (or in the future ARM
permission overlay extensions). The lifetime of those mappings are not
tied to the lifetime of the process, therefore, while the memory is
sealed, the allocators still need to free or discard the unused memory.
For example, with madvise(DONTNEED).
However, always allowing madvise(DONTNEED) on this range poses a security
risk. For example if a jump instruction crosses a page boundary and the
second page gets discarded, it will overwrite the target bytes with zeros
and change the control flow. Checking write-permission before the discard
operation allows us to control when the operation is valid. In this case,
the madvise will only succeed if the executing thread has PKEY write
permissions and PKRU changes are protected in software by control-flow
integrity.
Although the initial version of this patch series is targeting the Chrome
browser as its first user, it became evident during upstream discussions
that we would also want to ensure that the patch set eventually is a
complete solution for memory sealing and compatible with other use cases.
The specific scenario currently in mind is glibc's use case of loading and
sealing ELF executables. To this end, Stephen is working on a change to
glibc to add sealing support to the dynamic linker, which will seal all
non-writable segments at startup. Once this work is completed, all
applications will be able to automatically benefit from these new
protections.
In closing, I would like to formally acknowledge the valuable
contributions received during the RFC process, which were instrumental in
shaping this patch:
Jann Horn: raising awareness and providing valuable insights on the
destructive madvise operations.
Liam R. Howlett: perf optimization.
Linus Torvalds: assisting in defining system call signature and scope.
Theo de Raadt: sharing the experiences and insight gained from
implementing mimmutable() in OpenBSD.
MM perf benchmarks
==================
This patch adds a loop in the mprotect/munmap/madvise(DONTNEED) to
check the VMAs’ sealing flag, so that no partial update can be made,
when any segment within the given memory range is sealed.
To measure the performance impact of this loop, two tests are developed.
[8]
The first is measuring the time taken for a particular system call,
by using clock_gettime(CLOCK_MONOTONIC). The second is using
PERF_COUNT_HW_REF_CPU_CYCLES (exclude user space). Both tests have
similar results.
The tests have roughly below sequence:
for (i = 0; i < 1000, i++)
create 1000 mappings (1 page per VMA)
start the sampling
for (j = 0; j < 1000, j++)
mprotect one mapping
stop and save the sample
delete 1000 mappings
calculates all samples.
Below tests are performed on Intel(R) Pentium(R) Gold 7505 @ 2.00GHz,
4G memory, Chromebook.
Based on the latest upstream code:

Based on the result, for 6.8 kernel, sealing check adds
20-40 nano seconds, or around 50-100 CPU cycles, per VMA.
In addition, I applied the sealing to 5.10 kernel:

From 5.10 to 6.8
munmap: added 250-550 ns in time, or 500-1100 in cpu cycle, per vma.
mprotect: added 200-750 ns in time, or 500-1200 in cpu cycle, per vma.
madvise: added 33-50 ns in time, or 70-110 in cpu cycle, per vma.
In comparison to mseal, which adds 20-40 ns or 50-100 CPU cycles, the
increase from 5.10 to 6.8 is significantly larger, approximately ten times
greater for munmap and mprotect.
When I discuss the mm performance with Brian Makin, an engineer who worked
on performance, it was brought to my attention that such performance
benchmarks, which measuring millions of mm syscall in a tight loop, may
not accurately reflect real-world scenarios, such as that of a database
service. Also this is tested using a single HW and ChromeOS, the data
from another HW or distribution might be different. It might be best to
take this data with a grain of salt.
This patch (of 5):
Wire up mseal syscall for all architectures.

tracing: Remove second argument of __assign_str()
The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so that it no longer needs the second argument. The __assign_str() is always matched with __string() field that takes a field name and the source for that field: __string(field, source) The TRACE_EVENT() macro logic will save off the source value and then use that value to copy into the ring buffer via the __assign_str().

tracing/treewide: Remove second parameter of __assign_str()
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.
This means that with:
__string(field, mystring)
Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.
There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:
git grep -l __assign_str | while read a ; do
sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
mv /tmp/test-file $a;
done
I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.
Note, the same updates will need to be done for:
__assign_str_len()
__assign_rel_str()
__assign_rel_str_len()
I tested this with both an allmodconfig and an allyesconfig (build only for both).

ftrace: riscv: move from REGS to ARGS
This commit replaces riscv's support for FTRACE_WITH_REGS with support
for FTRACE_WITH_ARGS. This is required for the ongoing effort to stop
relying on stop_machine() for RISCV's implementation of ftrace.
The main relevant benefit that this change will bring for the above
use-case is that now we don't have separate ftrace_caller and
ftrace_regs_caller trampolines. This will allow the callsite to call
ftrace_caller by modifying a single instruction. Now the callsite can
do something similar to:
When not tracing: | When tracing:
func: func:
auipc t0, ftrace_caller_top auipc t0, ftrace_caller_top
nop <=========<Enable/Disable>=========> jalr t0, ftrace_caller_bottom
[...] [...]
The above assumes that we are dropping the support of calling a direct
trampoline from the callsite. We need to drop this as the callsite can't
change the target address to call, it can only enable/disable a call to
a preset target (ftrace_caller in the above diagram). We can later optimize
this by calling an intermediate dispatcher trampoline before ftrace_caller.
Currently, ftrace_regs_caller saves all CPU registers in the format of
struct pt_regs and allows the tracer to modify them. We don't need to
save all of the CPU registers because at function entry only a subset of
pt_regs is live:
|----------+----------+---------------------------------------------|
| Register | ABI Name | Description |
|----------+----------+---------------------------------------------|
| x1 | ra | Return address for traced function |
| x2 | sp | Stack pointer |
| x5 | t0 | Return address for ftrace_caller trampoline |
| x8 | s0/fp | Frame pointer |
| x10-11 | a0-1 | Function arguments/return values |
| x12-17 | a2-7 | Function arguments |
|----------+----------+---------------------------------------------|
See RISCV calling convention[1] for the above table.
Saving just the live registers decreases the amount of stack space
required from 288 Bytes to 112 Bytes.
Basic testing was done with this on the VisionFive 2 development board.
Note:
- Moving from REGS to ARGS will mean that RISCV will stop supporting
KPROBES_ON_FTRACE as it requires full pt_regs to be saved.
- KPROBES_ON_FTRACE will be supplanted by FPROBES see [2].

clang: work around asm input constraint problems
Work around clang problems with asm constraints that have multiple possibilities, particularly "g" and "rm". Clang seems to turn inputs like that into the most generic form, which is the memory input - but to make matters worse, clang won't even use a possible original memory location, but will spill the value to stack, and use the stack for the asm input. See https://github.com/llvm/llvm-project/issues/20571#issuecomment-980933442 for some explanation of why clang has this strange behavior, but the end result is that "g" and "rm" really end up generating horrid code.

virtio-mem: support suspend+resume
With virtio-mem, primarily hibernation is problematic: as the machine shuts down, the virtio-mem device loses its state. Powering the machine back up is like losing a bunch of DIMMs. While there would be ways to add limited support, suspend+resume is more commonly used for VMs and "easier" to support cleanly. s2idle can be supported without any device dependencies. Similarly, one would expect suspend-to-ram (i.e., S3) to work out of the box. However, QEMU currently unplugs all device memory when resuming the VM, using a cold reset on the "wakeup" path. In order to support S3, we need a feature flag for the device to tell us if memory remains plugged when waking up. In the future, QEMU will implement this feature. So let's always support s2idle and support S3 with plugged memory only if the device indicates support. Block hibernation early using the PM notifier. Trying to hibernate now fails early: # echo disk > /sys/power/state [ 26.455369] PM: hibernation: hibernation entry [ 26.458271] virtio_mem virtio0: hibernation is not supported.

vhost_task: Handle SIGKILL by flushing work and exiting
Instead of lingering until the device is closed, this has us handle SIGKILL by: 1. marking the worker as killed so we no longer try to use it with new virtqueues and new flush operations. 2. setting the virtqueue to worker mapping so no new works are queued. 3. running all the exiting works.

- topology_span_sane() optimization from Kyle Meyer;
- fns() rework from Kuan-Wei Chiu (used in
cpumask_local_spread() and other places); and
- headers cleanup from Andy.
This also adds a MAINTAINERS record for bitops API as it's unattended,
and I'd like to follow it closer.
Thanks,
Yury

more s390 updates for 6.10 merge window
- Switch read and write software bits for PUDs - Add missing hardware bits for PUDs and PMDs - Generate unwind information for C modules to fix GDB unwind error for vDSO functions - Create .build-id links for unstripped vDSO files to enable vDSO debugging with symbols - Use standard stack frame layout for vDSO generated stack frames to manually walk stack frames without DWARF information - Rework perf_callchain_user() and arch_stack_walk_user() functions to reduce code duplication - Skip first stack frame when walking user stack - Add basic checks to identify invalid instruction pointers when walking stack frames - Introduce and use struct stack_frame_vdso_wrapper within vDSO user wrapper code to automatically generate an asm-offset define. Also use STACK_FRAME_USER_OVERHEAD instead of STACK_FRAME_OVERHEAD to document that the code works with user space stack - Clear the backchain of the extra stack frame added by the vDSO user wrapper code. This allows the user stack walker to detect and skip the non-standard stack frame. Without this an incorrect instruction pointer would be added to stack traces. - Rewrite psw_idle() function in C to ease maintenance and further enhancements - Remove get_vtimer() function and use get_cpu_timer() instead - Mark psw variable in __load_psw_mask() as __unitialized to avoid superfluous clearing of PSW - Remove obsolete and superfluous comment about removed TIF_FPU flag - Replace memzero_explicit() and kfree() with kfree_sensitive() to fix warnings reported by Coccinelle - Wipe sensitive data and all copies of protected- or secure-keys from stack when an IOCTL fails - Both do_airq_interrupt() and do_io_interrupt() functions set CIF_NOHZ_DELAY flag. Move it in do_io_irq() to simplify the code - Provide iucv_alloc_device() and iucv_release_device() helpers, which can be used to deduplicate more or less identical IUCV device allocation and release code in four different drivers - Make use of iucv_alloc_device() and iucv_release_device() helpers to get rid of quite some code and also remove a cast to an incompatible function (clang W=1) - There is no user of iucv_root outside of the core IUCV code left. Therefore remove the EXPORT_SYMBOL - __apply_alternatives() contains a runtime check which verifies that the size of the to be patched code area is even. Convert this to a compile time check - Increase size of buffers for sending z/VM CP DIAGNOSE X'008' commands from 128 to 240 - Do not accept z/VM CP DIAGNOSE X'008' commands longer than maximally allowed - Use correct defines IPL_BP_NVME_LEN and IPL_BP0_NVME_LEN instead of IPL_BP_FCP_LEN and IPL_BP0_FCP_LEN ones to initialize NVMe reIPL block on 'scp_data' sysfs attribute update - Initialize the correct fields of the NVMe dump block, which were confused with FCP fields - Refactor macros for 'scp_data' (re-)IPL sysfs attribute to reduce code duplication - Introduce 'scp_data' sysfs attribute for dump IPL to allow tools such as dumpconf passing additional kernel command line parameters to a stand-alone dumper - Rework the CPACF query functions to use the correct RRE or RRF instruction formats and set instruction register fields correctly - Instead of calling BUG() at runtime force a link error during compile when a unsupported opcode is used with __cpacf_query() or __cpacf_check_opcode() functions - Fix a crash in ap_parse_bitmap_str() function on /sys/bus/ap/apmask or /sys/bus/ap/aqmask sysfs file update with a relative mask value - Fix "bindings complete" udev event which should be sent once all AP devices have been bound to device drivers and again when unbind/bind actions take place and all AP devices are bound again - Facility list alt_stfle_fac_list is nowhere used in the decompressor, therefore remove it there - Remove custom kprobes insn slot allocator in favour of the standard module_alloc() one, since kernel image and module areas are located within 4GB - Use kvcalloc() instead of kvmalloc_array() in zcrypt driver to avoid calling memset() with a large byte count and get rid of the sparse warning as result -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZkyx2BccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8PYZAP9KxEfTyUmIh61Gx8+m3BW5dy7p E2Q8yotlUpGj49ul+AD8CEAyTiWR95AlMOVZZLV/0J7XIjhALvpKAGfiJWkvXgc= =pife -----END PGP SIGNATURE----- Merge tag 's390-6.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Alexander Gordeev: - Switch read and write software bits for PUDs - Add missing hardware bits for PUDs and PMDs - Generate unwind information for C modules to fix GDB unwind error for vDSO functions - Create .build-id links for unstripped vDSO files to enable vDSO debugging with symbols - Use standard stack frame layout for vDSO generated stack frames to manually walk stack frames without DWARF information - Rework perf_callchain_user() and arch_stack_walk_user() functions to reduce code duplication - Skip first stack frame when walking user stack - Add basic checks to identify invalid instruction pointers when walking stack frames - Introduce and use struct stack_frame_vdso_wrapper within vDSO user wrapper code to automatically generate an asm-offset define.

remoteproc updates for v6.10
This makes the remoteproc core rproc_class const. DeviceTree bindings for a few different Qualcomm remoteprocs are updated to remove a range of validation warnings/errors. The Qualcomm SMD binding marks qcom,ipc deprecated, in favor or the mailbox interface. The TI K3 R5 remoteproc driver is updated to ensure that cores are powered up in the appropriate order. The driver also see a couple of fixes related to cleanups in error paths during probe. The Mediatek remoteproc driver is extended to support the MT8188 SCP core 1. Support for varying DRAM and IPI shared buffer sizes are introduced. This together with a couple of bug fixes and improvements to the driver. Support for the AMD-Xilinx Versal and Versal-NET platforms are added. Coredump support and support for parsing TCM information from DeviceTree is added to the Xilinx R5F remoteproc driver. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmZMEOcVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FchoP/jdIgdIac4LJo7JEV3PDELePmUHf OshGpV33zRonpXtLBM9xsN1jt1O1jpsJZ7J0sUSQJgob0y07GgImhiSIglgrmmgp fHortMyBVME+IRGiEEtB3s8LlbUe5O1gR9+nqnZM1tbxMTx1FVSMe1FvKXNQuLNV PXx095FrhfRptFMhOw0Rpngokcwh3hMoHhb/f1ZmdInBDvasuMd2B5kaWUv99hh2 zZKI3DhU0qIwSHtQ0Il+RmPnyCq4kbF29JCIB+9JVhd/sPCDwxbZlTnteoMSM7Ub tqOYan/GKatiCFO8Y8aF1kQyLRUR/Qujpnd+rxsV5zI3ouNOOhp9qbjsN5tQ7MH2 sG4zEV2qukMipeUoHlGHom8bq9Ux6sKnre3YZBRvlbW4IVWmrZgFWt9Z+D8N600Q AnUJaycc75tNQj2klx1vMAmdo/v+KhnhyTJoLzd/RPb6QqWbe1ABQH2w5t89XEKH XNfc4zGqJLoLpWod3kY68gBOuodWG6UqF6fPIsG4qLz5UGIV2fngzo6Ycdq5RhsP SWsmk8XSQCR8TBDN/l2xcFybXp5iGPJFste5PtrIQLP66P2CK9Ao96V0Otmpm91N SyhhcWkgS8LYvKBd9A2xPJHUXwroguaI9M49rwqDEvVDu0tsnDfJWx6p/CY7CAu1 myRj9UjCLjwYTBzE =YGw7 -----END PGP SIGNATURE----- Merge tag 'rproc-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "This makes the remoteproc core rproc_class const.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Skip E820 checks for MCFG ECAM regions for new (2016+) machines,
since there's no requirement to describe them in E820 and some
platforms require ECAM to work (Bjorn Helgaas)
- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific (Damien
Le Moal)
- Remove last user and pci_enable_device_io() (Heiner Kallweit)
- Wait for Link Training==0 to avoid possible race (Ilpo Järvinen)
- Skip waiting for devices that have been disconnected while
suspended (Ilpo Järvinen)
- Clear Secondary Status errors after enumeration since Master Aborts
and Unsupported Request errors are an expected part of enumeration
(Vidya Sagar)
MSI:
- Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas)
Error handling:
- Mask Genesys GL975x SD host controller Replay Timer Timeout
correctable errors caused by a hardware defect; the errors cause
interrupts that prevent system suspend (Kai-Heng Feng)
- Fix EDR-related _DSM support, which previously evaluated revision 5
but assumed revision 6 behavior (Kuppuswamy Sathyanarayanan)
ASPM:
- Simplify link state definitions and mask calculation (Ilpo
Järvinen)
Power management:
- Avoid D3cold for HP Pavilion 17 PC/1972 PCIe Ports, where BIOS
apparently doesn't know how to put them back in D0 (Mario
Limonciello)
CXL:
- Support resetting CXL devices; special handling required because
CXL Ports mask Secondary Bus Reset by default (Dave Jiang)
DOE:
- Support DOE Discovery Version 2 (Alexey Kardashevskiy)
Endpoint framework:
- Set endpoint BAR to be 64-bit if the driver says that's all the
device supports, in addition to doing so if the size is >2GB
(Niklas Cassel)
- Simplify endpoint BAR allocation and setting interfaces (Niklas
Cassel)
Cadence PCIe controller driver:
- Drop DT binding redundant msi-parent and pci-bus.yaml (Krzysztof
Kozlowski)
Cadence PCIe endpoint driver:
- Configure endpoint BARs to be 64-bit based on the BAR type, not the
BAR value (Niklas Cassel)
Freescale Layerscape PCIe controller driver:
- Convert DT binding to YAML (Frank Li)
MediaTek MT7621 PCIe controller driver:
- Add DT binding missing 'reg' property for child Root Ports
(Krzysztof Kozlowski)
- Fix theoretical string truncation in PHY name (Sergio Paracuellos)
NVIDIA Tegra194 PCIe controller driver:
- Return success for endpoint probe instead of falling through to the
failure path (Vidya Sagar)
Renesas R-Car PCIe controller driver:
- Add DT binding missing IOMMU properties (Geert Uytterhoeven)
- Add DT binding R-Car V4H compatible for host and endpoint mode
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Configure endpoint BARs to be 64-bit based on the BAR type, not the
BAR value (Niklas Cassel)
- Add DT binding missing maxItems to ep-gpios (Krzysztof Kozlowski)
- Set the Subsystem Vendor ID, which was previously zero because it
was masked incorrectly (Rick Wertenbroek)
Synopsys DesignWare PCIe controller driver:
- Restructure DBI register access to accommodate devices where this
requires Refclk to be active (Manivannan Sadhasivam)
- Remove the deinit() callback, which was only need by the
pcie-rcar-gen4, and do it directly in that driver (Manivannan
Sadhasivam)
- Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
up things like eDMA (Manivannan Sadhasivam)
- Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
to dw_pcie_ep_init() (Manivannan Sadhasivam)
- Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
reflect the actual functionality (Manivannan Sadhasivam)
- Call dw_pcie_ep_init_registers() directly from all the glue
drivers, not just those that require active Refclk from the host
(Manivannan Sadhasivam)
- Remove the "core_init_notifier" flag, which was an obscure way for
glue drivers to indicate that they depend on Refclk from the host
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)
- Add DT binding J722S SoC support (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Add DT binding missing num-viewport, phys and phy-name properties
(Jan Kiszka)
Miscellaneous:
- Constify and annotate with __ro_after_init (Heiner Kallweit)
- Convert DT bindings to YAML (Krzysztof Kozlowski)
- Check for kcalloc() failure in of_pci_prop_intr_map() (Duoming
Zhou)"
