sparc: Fix build with DEBUG_PAGEALLOC enabled. -
The generic library code already exports the generic function, this was
left-over from the ARM-specific version that just got removed.Signed-off-by: Linus Torvalds
-
Since commit 1eb19a12bd22 ("lib/sha1: use the git implementation of
SHA-1"), the ARM SHA1 routines no longer work. The reason? They
depended on the larger 320-byte workspace, and now the sha1 workspace is
just 16 words (64 bytes). So the assembly version would overwrite the
stack randomly.The optimized asm version is also probably slower than the new improved
C version, so there's no reason to keep it around. At least that was
the case in git, where what appears to be the same assembly language
version was removed two years ago because the optimized C BLK_SHA1 code
was faster.Reported-and-tested-by: Joachim Eastwood

When a Xen Dom0 kernel boots on a hypervisor, it gets access
to the raw-hardware ACPI tables. While it parses the idle tables
for the hypervisor's beneift, it uses HLT for its own idle.Rather than have xen scribble on pm_idle and access default_idle,
have it simply disable_cpuidle() so acpi_idle will not load and
architecture default HLT will be used.cc: xen-devel@lists.xensource.com

The Moorestown (MRST) Power Management Unit (PMU) driver
directs the SOC power states in the "Langwell" south complex (SCU).It hooks pci_platform_pm_ops[] and thus observes all PCI ".set_state"
requests. For devices in the SC, the pmu driver translates those
PCI requests into the appropriate commands for the SCU.The PMU driver helps implement S0i3, a deep system idle power idle state.
Entry into S0i3 is via cpuidle, just like regular processor c-states.
S0i3 depends on pre-conditions including uni-processor, graphics off,
and certain IO devices in the SC must be off. If those pre-conditions
are met, then the PMU allows cpuidle to enter S0i3, otherwise such requests
are demoted, either to Atom C4 or Atom C6.This driver is based on prototype work by Bruce Flemming,
Illyas Mansoor, Rajeev D. Muralidhar, Vishwesh M. Rudramuni,
Hari Seshadri and Sujith Thomas. The current driver also
includes contributions from H. Peter Anvin, Arjan van de Ven,
Kristen Accardi, and Yong Wang.Thanks for additional review feedback from Alan Cox and Randy Dunlap.

cmpxchg() is widely used by lockless code, including NMI-safe lockless
code. But on some architectures, the cmpxchg() implementation is not
NMI-safe, on these architectures the lockless code may need a
spin_trylock_irqsave() based implementation.This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that
NMI-safe lockless code can depend on it or provide different
implementation according to it.On many architectures, cmpxchg is only NMI-safe for several specific
operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch
only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).Signed-off-by: Huang Ying

This is the same as fd8a7de1 "x86: cpu-hotplug: Prevent softirq wakeup

Unlike on x86 this doesn't fix a bug on s390 since we do not have

initialization order like on x86. This should prevent bugs caused by
