Hi Linus,

Please pull some more powerpc fixes for 5.2.

This is a frustratingly large batch at rc5. Some of these were sent earlier but
were missed by me due to being distracted by other things, and some took a while
to track down due to needing manual bisection on old hardware. But still we
clearly need to improve our testing of KVM, and of 32-bit, so that we catch
these earlier.

cheers

  KVM: PPC: Book3S HV: Invalidate ERAT when flushing guest TLB entries (2019-06-20 22:11:25 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.2 #5

Seven fixes, all for bugs introduced this cycle.

The commit to add KASAN support broke booting on 32-bit SMP machines, due to a
refactoring that moved some setup out of the secondary CPU path.

A fix for another 32-bit SMP bug introduced by the fast syscall entry
implementation for 32-bit BOOKE. And a build fix for the same commit.

Our change to allow the DAWR to be force enabled on Power9 introduced a bug in
KVM, where we clobber r3 leading to a host crash.

The same commit also exposed a previously unreachable bug in the nested KVM
handling of DAWR, which could lead to an oops in a nested host.

One of the DMA reworks broke the b43legacy WiFi driver on some people's
powermacs, fix it by enabling a 30-bit ZONE_DMA on 32-bit.

A fix for TLB flushing in KVM introduced a new bug, as it neglected to also
flush the ERAT, this could lead to memory corruption in the guest.

Thanks to:
  Aaro Koskinen, Christoph Hellwig, Christophe Leroy, Larry Finger, Michael
  Neuling, Suraj Jitindar Singh.
