Linus Torvalds 7561393908 powerpc fixes for 5.8 #3 
One fix for the interrupt rework we did last release which broke KVM-PR.
 
 Three commits fixing some fallout from the READ_ONCE() changes interacting badly
 with our 8xx 16K pages support, which uses a pte_t that is a structure of 4
 actual PTEs.
 
 A cleanup of the 8xx pte_update() to use the newly added pmd_off().
 
 A fix for a crash when handling an oops if CONFIG_DEBUG_VIRTUAL is enabled.
 
 A minor fix for the SPU syscall generation.
 
 Thanks to:

   Nicholas Piggin.
