Akihiro Nagai 547a92e0ae perf script: Unify the expressions indicating "unknown"
The perf script command uses various expressions to indicate "unknown".

It is unfriendly for user scripts to parse it. So, this patch unifies
the expressions to "[unknown]".

Andreas Herrmann 5b68edc91c x86/microcode_amd: Add support for CPU family specific container files
We've decided to provide CPU family specific container files
(starting with CPU family 15h). E.g. for family 15h we have to
load microcode_amd_fam15h.bin instead of microcode_amd.bin

Rationale is that starting with family 15h patch size is larger
than 2KB which was hard coded as maximum patch size in various
microcode loaders (not just Linux).

Container files which include patches larger than 2KB cause
different kinds of trouble with such old patch loaders. Thus we
have to ensure that the default container file provides only
patches with size less than 2KB.

the variable 'phdrs' goes out of scope --> leak.

Cliff Wickman d2ebc71d47 x86/uv: Fix uninitialized spinlocks
Initialize two spinlocks in tlb_uv.c and also properly define/initialize
the uv_irq_lock.

The lack of explicit initialization seems to be functionally
harmless, but it is diagnosed when these are turned on:

        CONFIG_DEBUG_SPINLOCK=y
        CONFIG_DEBUG_MUTEXES=y
        CONFIG_DEBUG_LOCK_ALLOC=y
        CONFIG_LOCKDEP=y
