RISC-V updates for v5.3-rc3
Three minor RISC-V-related changes for v5.3-rc3:
- Add build ID to VDSO builds to avoid a double-free in perf when
libelf isn't used
- Align the RV64 defconfig to the output of "make savedefconfig" so
subsequent defconfig patches don't get out of hand
- Drop a superfluous DT property from the FU540 SoC DT data (since it
must be already set in board data that includes it)

cgroup: kselftest: relax fs_spec checks
On my laptop most memcg kselftests were being skipped because it claimed
cgroup v2 hierarchy wasn't mounted, but this isn't correct. Instead, it
seems current systemd HEAD mounts it with the name "cgroup2" instead of
"cgroup":
% grep cgroup /proc/mounts
cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0
I can't think of a reason to need to check fs_spec explicitly
since it's arbitrary, so we can just rely on fs_vfstype.
After these changes, `make TARGETS=cgroup kselftest` actually runs the
cgroup v2 tests in more cases.

coredump: split pipe command whitespace before expanding template
Save the offsets of the start of each argument to avoid having to update
pointers to each argument after every corename krealloc and to avoid
having to duplicate the memory for the dump command.
Executable names containing spaces were previously being expanded from
%e or %E and then split in the middle of the filename. This is
incorrect behaviour since an argument list can represent arguments with
spaces.
The splitting could lead to extra arguments being passed to the core
dump handler that it might have interpreted as options or ignored
completely.
Core dump handlers that are not aware of this Linux kernel issue will be
using %e or %E without considering that it may be split and so they will
be vulnerable to processes with spaces in their names breaking their
argument list. If their internals are otherwise well written, such as
if they are written in shell but quote arguments, they will work better
after this change than before. If they are not well written, then there
is a slight chance of breakage depending on the details of the code but
they will already be fairly broken by the split filenames.
Core dump handlers that are aware of this Linux kernel issue will be
placing %e or %E as the last item in their core_pattern and then
aggregating all of the remaining arguments into one, separated by
spaces. Alternatively they will be obtaining the filename via other
methods. Both of these will be compatible with the new arrangement.
A side effect from this change is that unknown template types (for
example %z) result in an empty argument to the dump handler instead of
the argument being dropped. This is a desired change as:
It is easier for dump handlers to process empty arguments than dropped
ones, especially if they are written in shell or don't pass each
template item with a preceding command-line option in order to
differentiate between individual template types. Most core_patterns in
the wild do not use options so they can confuse different template types
(especially numeric ones) if an earlier one gets dropped in old kernels.
If the kernel introduces a new template type and a core_pattern uses it,
the core dump handler might not expect that the argument can be dropped
in old kernels.
For example, this can result in security issues when %d is dropped in
old kernels. This happened with the corekeeper package in Debian and
resulted in the interface between corekeeper and Linux having to be
rewritten to use command-line options to differentiate between template
types.
The core_pattern for most core dump handlers is written by the handler
author who would generally not insert unknown template types so this
change should be compatible with all the core dump handlers that exist.

page flags: prioritize kasan bits over last-cpuid
ARM64 randdconfig builds regularly run into a build error, especially
when NUMA_BALANCING and SPARSEMEM are enabled but not SPARSEMEM_VMEMMAP:
#error "KASAN: not enough bits in page flags for tag"
The last-cpuid bits are already contitional on the available space, so
the result of the calculation is a bit random on whether they were
already left out or not.
Adding the kasan tag bits before last-cpuid makes it much more likely to
end up with a successful build here, and should be reliable for
randconfig at least, as long as that does not randomize NR_CPUS or
NODES_SHIFT but uses the defaults.
In order for the modified check to not trigger in the x86 vdso32 code
where all constants are wrong (building with -m32), enclose all the
definitions with an #ifdef.

ubsan: build ubsan.c more conservatively
objtool points out several conditions that it does not like, depending
on the combination with other configuration options and compiler
variants:
stack protector:
lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch()+0xbf: call to __stack_chk_fail() with UACCESS enabled
lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch_v1()+0xbe: call to __stack_chk_fail() with UACCESS enabled
stackleak plugin:
lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch()+0x4a: call to stackleak_track_stack() with UACCESS enabled
lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch_v1()+0x4a: call to stackleak_track_stack() with UACCESS enabled
kasan:
lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch()+0x25: call to memcpy() with UACCESS enabled
lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch_v1()+0x25: call to memcpy() with UACCESS enabled
The stackleak and kasan options just need to be disabled for this file
as we do for other files already. For the stack protector, we already
attempt to disable it, but this fails on clang because the check is
mixed with the gcc specific -fno-conserve-stack option. According to
Andrey Ryabinin, that option is not even needed, dropping it here fixes
the stackprotector issue.

mm: compaction: avoid 100% CPU usage during compaction when a task is killed
"howaboutsynergy" reported via kernel buzilla number 204165 that
compact_zone_order was consuming 100% CPU during a stress test for
prolonged periods of time. Specifically the following command, which
should exit in 10 seconds, was taking an excessive time to finish while
the CPU was pegged at 100%.
stress -m 220 --vm-bytes 1000000000 --timeout 10
Tracing indicated a pattern as follows
stress-3923 [007] 519.106208: mm_compaction_isolate_migratepages: range=(0x70bb80 ~ 0x70bb80) nr_scanned=0 nr_taken=0

stress-3923 [007] 519.106242: mm_compaction_isolate_migratepages: range=(0x70bb80 ~ 0x70bb80) nr_scanned=0 nr_taken=0
Note that compaction is entered in rapid succession while scanning and
isolating nothing. The problem is that when a task that is compacting
receives a fatal signal, it retries indefinitely instead of exiting
while making no progress as a fatal signal is pending.
It's not easy to trigger this condition although enabling zswap helps on
the basis that the timing is altered. A very small window has to be hit
for the problem to occur (signal delivered while compacting and
isolating a PFN for migration that is not aligned to SWAP_CLUSTER_MAX).
This was reproduced locally -- 16G single socket system, 8G swap, 30%
zswap configured, vm-bytes 22000000000 using Colin Kings stress-ng
implementation from github running in a loop until the problem hits).
Tracing recorded the problem occurring almost 200K times in a short
window. With this patch, the problem hit 4 times but the task existed
normally instead of consuming CPU.
This problem has existed for some time but it was made worse by commit

mm: migrate: fix reference check race between __find_get_block() and migration
buffer_migrate_page_norefs() can race with bh users in the following
way:
CPU1 CPU2
buffer_migrate_page_norefs()
buffer_migrate_lock_buffers()
checks bh refs
spin_unlock(&mapping->private_lock)
__find_get_block()
spin_lock(&mapping->private_lock)
grab bh ref
spin_unlock(&mapping->private_lock)
move page do bh work
This can result in various issues like lost updates to buffers (i.e.
metadata corruption) or use after free issues for the old page.
This patch closes the race by holding mapping->private_lock while the
mapping is being moved to a new page. Ordinarily, a reference can be
taken outside of the private_lock using the per-cpu BH LRU but the
references are checked and the LRU invalidated if necessary. The
private_lock is held once the references are known so the buffer lookup
slow path will spin on the private_lock. Between the page lock and
private_lock, it should be impossible for other references to be
acquired and updates to happen during the migration.
A user had reported data corruption issues on a distribution kernel with
a similar page migration implementation as mainline. The data
corruption could not be reproduced with this patch applied. A small
number of migration-intensive tests were run and no performance problems
were noted.

Merge tag 'drm-fixes-2019-08-02-1' of git://anongit.freedesktop.org/drm/drm
Pull more drm fixes from Daniel Vetter:
"Dave sends his pull, everyone realizes they've been asleep at the
wheel and hits send on their own pulls :-/
Normally I'd just ignore these all because w/e for me and Dave. But
this time around the latecomers also included drm-intel-fixes, which
failed to send out a -fixes pull thus far for this release (screwed up
vacation coverage, despite that 2/3 maintainers were around ... they
all look appropriately guilty), and that really is overdue to get
landed.
And since I had to do a pull request anyway I pulled the other two
late ones too.
intel fixes (didn't have any ever since the main merge window pull):
- gvt fixes (2 cc: stable)
- fix gpu reset vs mm-shrinker vs wakeup fun (needed a few patches)
- two gem locking fixes (one cc: stable)
- pile of misc fixes all over with minor impact, 6 cc: stable, others
from this window
exynos:
- misc minor fixes
misc:
- some build/Kconfig fixes
- regression fix for vm scalability perf test which seems to mostly
exercise dmesg/console logging ...
- the vgem cache flush fix for arm64 broke the world on x86, so
that's reverted again

add swiotlb support to arm
This fixes a cascade of regressions that originally started with
the addition of the ia64 port, but only got fatal once we removed
most uses of block layer bounce buffering in Linux 4.18.
The reason is that while the original i386/PAE code that was the first
architecture that supported > 4GB of memory without an iommu decided to
leave bounce buffering to the subsystems, which in those days just mean
block and networking as no one else consumer arbitrary userspace memory.
Later with ia64, x86_64 and other ports we assumed that either an iommu
or something that fakes it up ("software IOTLB" in beautiful Intel
speak) is present and that subsystems can rely on that for dealing with
addressing limitations in devices. Except that the ARM LPAE scheme
that added larger physical address to 32-bit ARM did not follow that
scheme and thus only worked by chance and only for block and networking
I/O directly to highmem.
Long story, short fix - add swiotlb support to arm when build for LPAE
platforms, which actuallys turns out to be pretty trivial with the
modern dma-direct / swiotlb code to fix the Linux 4.18-ish regression.

arm64: Make debug exception handlers visible from RCU
Make debug exceptions visible from RCU so that synchronize_rcu() correctly track the debug exception handler. This also introduces sanity checks for user-mode exceptions as same as x86's ist_enter()/ist_exit(). The debug exception can interrupt in idle task. For example, it warns if we put a kprobe on a function called from idle task as below. The warning message showed that the rcu_read_lock() caused this problem. But actually, this means the RCU is lost the context which is already in NMI/IRQ. /sys/kernel/debug/tracing # echo p default_idle_call >> kprobe_events /sys/kernel/debug/tracing # echo 1 > events/kprobes/enable /sys/kernel/debug/tracing # [ 135.122237] [ 135.125035] ============================= [ 135.125310] WARNING: suspicious RCU usage [ 135.125581] 5.2.0-08445-g9187c508bdc7 #20 Not tainted [ 135.125904] ----------------------------- [ 135.126205] include/linux/rcupdate.h:594 rcu_read_lock() used illegally while idle!

arm64: kprobes: Recover pstate.D in single-step exception handler
kprobes manipulates the interrupted PSTATE for single step, and doesn't restore it. Thus, if we put a kprobe where the pstate.D (debug) masked, the mask will be cleared after the kprobe hits. Moreover, in the most complicated case, this can lead a kernel crash with below message when a nested kprobe hits. [ 152.118921] Unexpected kernel single-step exception at EL1 When the 1st kprobe hits, do_debug_exception() will be called. At this point, debug exception (= pstate.D) must be masked (=1). But if another kprobes hits before single-step of the first kprobe (e.g. inside user pre_handler), it unmask the debug exception (pstate.D = 0) and return. Then, when the 1st kprobe setting up single-step, it saves current DAIF, mask DAIF, enable single-step, and restore DAIF. However, since "D" flag in DAIF is cleared by the 2nd kprobe, the single-step exception happens soon after restoring DAIF. This has been introduced by commit |

drm/exynos: fix missing decrement of retry counter
Currently the retry counter is not being decremented, leading to a
potential infinite spin if the scalar_reads don't change state.

drm/exynos: add CONFIG_MMU dependency
Compile-testing this driver on a NOMMU configuration shows a link failure:
drivers/gpu/drm/exynos/exynos_drm_gem.o: In function `exynos_drm_gem_fault':
exynos_drm_gem.c:(.text+0x484): undefined reference to `vmf_insert_mixed'
Add a CONFIG_MMU dependency to ensure we only enable this in configurations
that build correctly.
Many other drm drivers have the same dependency. It would be nice to
make this work in MMU-less configurations, but evidently nobody has
ever needed this so far.

drm/exynos: using dev_get_drvdata directly
Several drivers cast a struct device pointer to a struct platform_device pointer only to then call platform_get_drvdata(). To improve readability, these constructs can be simplified by using dev_get_drvdata() directly.

s390/dasd: fix endless loop after read unit address configuration
After getting a storage server event that causes the DASD device driver
to update its unit address configuration during a device shutdown there is
the possibility of an endless loop in the device driver.
In the system log there will be ongoing DASD error messages with RC: -19.
The reason is that the loop starting the ruac request only terminates when
the retry counter is decreased to 0. But in the sleep_on function there are
early exit paths that do not decrease the retry counter.
Prevent an endless loop by handling those cases separately.
Remove the unnecessary do..while loop since the sleep_on function takes
care of retries by itself.
