ace149e083 filemap: Fix bounds checking in filemap_read()
If the caller supplies an iocb->ki_pos value that is close to the
filesystem upper limit, and an iterator with a count that causes us to
overflow that limit, then filemap_read() enters an infinite loop.

This behaviour was discovered when testing xfstests generic/525 with the
"localio" optimisation for loopback NFS mounts.

b6cd7adec0 rtc: st-lpc: Use IRQF_NO_AUTOEN flag in request_irq()
If request_irq() fails in st_rtc_probe(), there is no need to enable
the irq, and if it succeeds, disable_irq() after request_irq() still has
a time gap in which interrupts can come.

request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when
request IRQ.

e5eab1aeae rtc: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/rtc to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

8eea62ff94 rust: sync: add global lock support
Add support for creating global variables that are wrapped in a mutex or
spinlock.

The implementation here is intended to replace the global mutex
workaround found in the Rust Binder RFC [1]. In both cases, the global
lock must be initialized before first use. The macro is unsafe to use
for the same reason.

The separate initialization step is required because it is tricky to
access the value of __ARCH_SPIN_LOCK_UNLOCKED from Rust. Doing so will
require changes to the C side. That change will happen as a follow-up to
this patch.

5dbcb1c190 RDMA/hns: Fix out-of-order issue of requester when setting FENCE
The FENCE indicator in hns WQE doesn't ensure that response data from
a previous Read/Atomic operation has been written to the requester's
memory before the subsequent Send/Write operation is processed. This
may result in the subsequent Send/Write operation accessing the original
data in memory instead of the expected response data.

Unlike FENCE, the SO (Strong Order) indicator blocks the subsequent
operation until the previous response data is written to memory and a
bresp is returned. Set the SO indicator instead of FENCE to maintain
strict order.

5b881c1f83 powerpc/irq: use seq_put_decimal_ull_width() for decimal values
On a system with n CPUs and m interrupts, there will be n*m decimal
values yielded via seq_printf(.."%10u "..) which is less efficient
than seq_put_decimal_ull_width(), stress reading /proc/interrupts
indicates ~30% performance improvement with this patch.

44e5d21e6d powerpc/pseries: Fix KVM guest detection for disabling hardlockup detector
As per the kernel documentation[1], hardlockup detector should
be disabled in KVM guests as it may give false positives. On
PPC, hardlockup detector is enabled inside KVM guests because
disable_hardlockup_detector() is marked as early_initcall and it
relies on kvm_guest static key (is_kvm_guest()) which is initialized
later during boot by check_kvm_guest(), which is a core_initcall.
check_kvm_guest() is also called in pSeries_smp_probe(), which is called
before initcalls, but it is skipped if KVM guest does not have doorbell
support or if the guest is launched with SMT=1.

Call check_kvm_guest() in disable_hardlockup_detector() so that
is_kvm_guest() check goes through fine and hardlockup detector can be
disabled inside the KVM guest.

fb90dca828 fadump: reserve param area if below boot_mem_top
The param area is a memory region where the kernel places additional
command-line arguments for fadump kernel. Currently, the param memory
area is reserved in fadump kernel if it is above boot_mem_top. However,
it should be reserved if it is below boot_mem_top because the fadump
kernel already reserves memory from boot_mem_top to the end of DRAM.

Currently, there is no impact from not reserving param memory if it is
below boot_mem_top, as it is not used after the early boot phase of the
fadump kernel. However, if this changes in the future, it could lead to
issues in the fadump kernel.

f4892c68ec powerpc/fadump: allocate memory for additional parameters early
Memory for passing additional parameters to fadump capture kernel
is allocated during subsys_initcall level, using memblock. But
as slab is already available by this time, allocation happens via
the buddy allocator. This may work for radix MMU but is likely to
fail in most cases for hash MMU as hash MMU needs this memory in
the first memory block for it to be accessible in real mode in the
capture kernel (second boot). So, allocate memory for additional
parameters area as soon as MMU mode is obvious.

  ------------[ cut here ]------------

The function in question, _sub_I_65535_1 is some sort of trampoline
generated for KASAN, and is in the .text.startup section. That section
is part of INIT_TEXT, meaning is_kernel_inittext() returns true for it.

But the script that determines how many out-of-line ftrace stubs are
needed isn't doesn't consider .text.startup as inittext, leading to
there not being enough space for the init stubs.

Conversely the logic to calculate how many stubs are needed for the text
section isn't filtering out the symbols in .text.startup and so ends up
over counting.

Fix both problems by calculating the total number of stubs first, then
the number that count as inittext, and then subtract the latter from the
former to get the count for the text section.

49988a7975 mei: vsc: Do not re-enable interrupt from vsc_tp_reset()
The only 2 callers of vsc_tp_reset() are:

1. mei_vsc_hw_reset(), which immediataly calls vsc_tp_intr_disable()
   afterwards.

2. vsc_tp_shutdown() which immediately calls free_irq() afterwards.

So neither actually wants the interrupt to be enabled after resetting
the chip and having the interrupt enabled for a short time afer
the reset is undesirable.

Drop the enable_irq() call from vsc_tp_reset(), so that the interrupt
is left disabled after vsc_tp_reset().

fe0ebeafc3 staging: greybus: uart: Fix atomicity violation in get_serial_info()
Our static checker found a bug where set_serial_info() uses a mutex, but
get_serial_info() does not. Fortunately, the impact of this is relatively
minor. It doesn't cause a crash or any other serious issues. However, if a
race condition occurs between set_serial_info() and get_serial_info(),
there is a chance that the data returned by get_serial_info() will be
meaningless.

In commit 24cc57d8fa ("padata: Honor the caller's alignment in case of

added, making 'ps.chunk_size = 1U' redundant and never executed.

a10549fcce crypto: inside-secure - Fix the return value of safexcel_xcbcmac_cra_init()
The commit 320406cb60 ("crypto: inside-secure - Replace generic aes
with libaes") replaced crypto_alloc_cipher() with kmalloc(), but did not
modify the handling of the return value. When kmalloc() returns NULL,
PTR_ERR_OR_ZERO(NULL) returns 0, but in fact, the memory allocation has
failed, and -ENOMEM should be returned.
