Linus Torvalds a8282bf087 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.

   Neuling, Suraj Jitindar Singh.

Pull powerpc fixes from Michael Ellerman:
 "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.

  Summary: 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
