Subject: [GIT PULL] x86 fixes

Linus,

Please pull the latest x86-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-urgent-for-linus

   # HEAD: 6bd3357b6181bd38c1a757168a8842e09ec6f3fb Merge branches 'x86/hyperv', 'x86/kdump' and 'x86/misc' into x86/urgent, to pick up single-commit branches

Misc fixes:

 - three fixes and a cleanup for the resctrl code,
 - a HyperV fix,
 - a fix to /proc/kcore contents in live debugging sessions,
 - a fix for the x86 decoder opcode map.

 Thanks,

	Ingo
