80aa9bf0d8 [IA64] arch/ia64/hp/common/sba_iommu.c: Rename dev_info to adi
There is a macro called dev_info that prints struct device specific
information.  Having variables with the same name can be confusing and
prevents conversion of the macro to a function.

Rename the existing dev_info variables to something else in preparation
to converting the dev_info macro to a function.

717e7c2672 ARM: remove 'select GENERIC_TIME'
GENERIC_TIME is now enabled by default, so 'select GENERIC_TIME'
is redundant.  Remove them.

dd2fdd264e sh64: provide a stub per_cpu_trap_init() definition.
This is needed to fix up the build at the moment. Gradually this will be
reworked to follow the 32-bit initialization path and deal with delayed
VBR initialization.

c77b29db74 sh: fix up CONFIG_KEXEC=n build.
The reserve_crashkernel() definition is in asm/kexec.h which is only
dragged in via linux/kexec.h if CONFIG_KEXEC is set. Just switch over to
asm/kexec.h unconditionally to fix up the build.

c59bd56882 x86, hweight: Use a 32-bit popcnt for __arch_hweight32()
Use a 32-bit popcnt instruction for __arch_hweight32(), even on
x86-64.  Even though the input register will *usually* be
zero-extended due to the standard operation of the hardware, it isn't
necessarily so if the input value was the result of truncating a
64-bit operation.

Note: the POPCNT32 variant used on x86-64 has a technically
unnecessary REX prefix to make it five bytes long, the same as a CALL
instruction, therefore avoiding an unnecessary NOP.

adbf6e6952 m68k: invoke oom-killer from page fault
As explained in commit 1c0fe6e3bd, we want to call the architecture independent
oom killer when getting an unexplained OOM from handle_mm_fault, rather than
simply killing current.

b1f3bb494e m68k: Remove BKL from rtc implementations
m68k does not support SMP. The access to the rtc is already serialized
with local_irq_save/restore which is sufficient on UP.

The open() protection in arch/m68k/mvme16x/rtc.c is not pretty but
sufficient on UP and safe w/o the BKL.

open() in arch/m68k/bvme6000/rtc.c can do with the same atomic logic
as arch/m68k/mvme16x/rtc.c

98830bc996 ARM: 6136/1: ARCH_REQUIRE_GPIOLIB selects GENERIC_GPIO
The ARCH_REQUIRE_GPIOLIB config option will select GPIOLIB which
in turn will select GENERIC_GPIO.  Because of this, there is no
reason to do the select GENERIC_GPIO in arch/arm/Kconfig for the
architectures that have ARCH_REQUIRE_GPIOLIB.
