Subject: linux-next: build failure after merge of the powerpc tree

Hi all,

After merging the powerpc tree, today's linux-next build (powerpc
allyesconfig) failed like this:

arch/powerpc/kernel/fadump.c: In function 'crash_fadump':  
arch/powerpc/kernel/fadump.c:731:28: error: 'INTERRUPT_SYSTEM_RESET' undeclared (first use in this function)
  731 |  if (TRAP(&(fdh->regs)) == INTERRUPT_SYSTEM_RESET) {
      |                            ^~~~~~~~~~~~~~~~~~~~~~
arch/powerpc/kernel/fadump.c:731:28: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

  7153d4bf0b37 ("powerpc/traps: Enhance readability for trap types")

I have applied the following patch for today.
