Actually, I'd prefer if I take it through the tip tree:

https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/log/?h=x86/urgent

because it is needed for the following patch by tglx:

6867ee8bcb75 x86/cpufeatures: Force disable X86_FEATURE_ENQCMD and remove update_pasid()
db099bafbf5e dmaengine: idxd: Use cpu_feature_enabled()

if you don't mind.

I'll be sending this to Linus this weekend.

Thx.
