[Devel] [PATCH RH9 13/30] ~x86/microcode/intel: hide warning on high order allocation for microcode area

[Andrey Zhadchenko]

From: Konstantin Khorenko <khorenko at virtuozzo.com>

Microcode blob can require a page of 3rd order and loading microcode
data is done using "wrmsr" asm instruction, so we cannot substitute
kmalloc() with kvmalloc() here.

Let's just hide the warning for this scenario, microcode update is a
rare operation anyway.
