Subject: [GIT PULL] x86/cleanup changes for v3.3
Linus,
Please pull the latest x86-cleanups-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-cleanups-for-linus
Thanks,
Ingo
------------------>
Borislav Petkov (1):
x86, CPU: Drop superfluous get_cpu_cap() prototype
Ferenc Wagner (1):
x86: Replace the EVT_TO_HPET_DEV() macro with an inline function
H Hartley Sweeten (2):
arch/x86/kernel/ptrace.c: Quiet sparse noise
arch/x86/mm/pageattr.c: Quiet sparse noise; local functions should be static
Jesper Juhl (2):
x86: Use "do { } while(0)" for empty flush_tlb_fix_spurious_fault() macro
x86: Use "do { } while(0)" for empty lock_cmos()/unlock_cmos() macros
Thomas Meyer (1):
x86: Use kmemdup() in copy_thread(), rather than duplicating its implementation
