Subject[PATCH 0/7] x86, xsave: some code cleanups and reworks, -v2
Hans Peter, Suresh, and Cyrill, thanks for your feedback.

This is version 2 of the patch series.

Patches 2, 4, 7 are unchanged compared to -v1.

Patch 1 folds the initialization code into one patch. fpu_init() is
now called before xsave_init(). xsave_init() can later overwrite
xstate_size based on xstate features.

Patch 3 replaces all hardcoded XSTATE_CPUID values know. cpuid_level
is now taken from boot_cpu_data.

Patches 5 and 6 are new:
* add __init attribute to setup_xstate_features()
* disable xsave in i387 emulation mode
