Revert "[PATCH] Enforce "unsigned long flags;" when spinlocking"
This reverts commit ee3ce191e8eaa4cc15c51a28b34143b36404c4f5, since it
broke on at least ARM, MIPS and PA-RISC due to complicated header file
dependencies.
Conflicts in include/linux/spinlock.h (due to the "nested" variety
fixes) fixed up by hand.
