[ Upstream commit a6cae77f1bc89368a4e2822afcddc45c3062d499 ]
commit 7c6986ade69e ("powerpc/stacktrace: Fix spurious "stale" traces in raise_backtrace_ipi()") introduces udelay() call without including the linux/delay.h header. This may happen to work on master but the header that declares the functionshould be included nonetheless.
