Note that the following bunch of patches had lots of conflicts

* x86/cpufeature, x86/mm/pkeys: Add protection keys related CPUID definitions
* x86/mm/pkeys: Fix mismerge of protection keys CPUID bits
* x86/cpu: Add detection of AMD RAS Capabilities
* x86/cpufeature, x86/mm/pkeys: Fix broken compile-time disabling of pkeys
* x86/cpufeature: Make sure DISABLED/REQUIRED macros are updated

most of them due to conflicting with "d8d8ad461662b UBUNTU: SAUCE: x86/cpufeatures: Move CPUID_7_EDX CPUID bits to word 18". I think I resolved them correctly but an extra set of eyes might be good.

Furthermore, there was another conflict with:

 * loop: add recursion validation to LOOP_CHANGE_FD

due to conflicting with "dee5220cf5 UBUNTU: SAUCE: AUFS ". In the function loop_set_fd() the upstream patch tries to remove the local variable 'f' with the AUFS code appears to be using. I kept 'f'

The following upstream patches were skipped because they were either already applied or their code was somehow already present:

47ff5bc938c8 x86/cpufeature: Move some of the scattered feature bits to x86_capability
0f66fae5d614 x86/cpufeature: Cleanup get_cpu_cap()
7b2330a33983 x86/cpufeature: Carve out X86_FEATURE_*
febdf817e79b x86/cpufeature: Update cpufeaure macros
