Use put_unaligned_le32 rather than using byte ordering function and
memcpy which makes code clear.

A new feature Range Selector (RS) has been added to GIC specification
in order to support more than 16 CPUs at affinity level 0. New fields
are introduced in SGI system registers (ICC_SGI0R_EL1, ICC_SGI1R_EL1

The patch set simplifies the existing hash level switching code for

The patch supports the options to switch TCP hash level between

SPARC provides lzcnt instruction (with VIS3) which can be used to
optimize fls, __fls and fls64 functions. For the systems that supports
lzcnt instruction, we now do boot time patching to use sparc
optimized fls, __fls and fls64 functions.

For T4 and above, patch fls and __fls functions
at the boot time to use lzcnt instruction.

Applied to net-next.
Can not replicate, issue discovered in fuzzing. Stack trace below.

If the 'arat' cpu flag is set, then the conditionals in intel_idle() that
guard calling tick_broadcast_enter()/exit() will never be true. Use
static_cpu_has(X86_FEATURE_ARAT) to create a fast path to replace
the conditional.

The purpose of patch "linux/types.h: enable endian checks for all
sparse builds" was to encourage driver authors to annotate
endianness correctly in their drivers. However, since that patch
went upstream no endianness annotations in drivers have been fixed.
I think that this shows that the followed
Our routines look at tscdeadline and period when deciding state of a
timer. The timer is disarmed when switching between TSC deadline and
other modes, so we should set everything to disarmed state.

Various bugs that incorrectly injected a timer interrupt.
Going to work on kvm-unit-tests for this too.
