Currently, __inline is #defined as inline in compiler_types.h, so this
should not change functionality. It is preparation for removing said
#define.
While at it, change some "inline static" to the customary "static

gcc >= 9.1 allows one to overrule the estimated size by using "asm
inline" instead of just "asm". So replace asm by the helper
asm_inline, which for older gccs just expands to asm.

expect, but I think we do want the asm_inline thing available sooner
or later, so this is just to get the ball rolling.

Putting the ia32_compat member after the pkey members is deliberate to
keep the latter two (when present) in the same 4-byte unit.

init_mm is sizeof(long) larger than it needs to be. Use the
CPU_BITS_NONE macro meant for this, which will initialize just the
indices 0...(BITS_TO_LONGS(NR_CPUS)-1) and hence make the array size
actually BITS_TO_LONGS(NR_CPUS).

This should really be handled in the watchdog core for any driver that
reports max_hw_heartbeat_ms.
The same pattern appears in aspeed_wdt.c. I don't have the hardware, but
