[PATCH 0/3] PTI x86-32 Updates and Fixes

[Joerg Roedel]

Hi,

here are three patches on-top of tip/x86/pti to update the
vmallo_fault() fix and also with another important fix.

The first two patches remove the WARN_ON_ONCE(in_nmi) from
the vmalloc_fault() function and revert the previous fix, as
discussed at the last patch-set.

The third patch is an important fix for a silent memory
corruption issue found by the trinity fuzzer, which did take
a while to track down. But I found it and with the fix the
fuzzer already runs for couple of hours now and the VM is
still alive.

Regards,

	Joerg
