[PATCH 0/2] x86/entry: xorq->xorl; idtentry size reduction

[Dominik Brodowski]

These two patches apply on top of tip/pti.

The first one cuts the idtentry macro as suggested by Linus.
I'm not sure whether this patch yet needs an explicit SOB by
him though. It was previously sent as RFC / testing only patch
"8/7" to the previous x86/entry-related series, cf.
http://lkml.kernel.org/r/20180211104949.12992-9-linux@xxxxxxxxxxxxxxxxxxxx

The other one replaces the xorq-based register cleaning with an
equivalent xorl-based version, which is supposed to be faster on
some architectures.

Thanks,
	Dominik
