# 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
