lockdep: warn about lockdep disabling after kernel taint, fix
Impact: build fix for Sparc and s390 Stephen Rothwell reported that the Sparc build broke: In file included from kernel/panic.c:12: include/linux/debug_locks.h: In function '__debug_locks_off': include/linux/debug_locks.h:15: error: implicit declaration of function 'xchg' due to: 9eeba61: lockdep: warn about lockdep disabling after kernel taint There is some inconsistency between architectures about where exactly xchg() is defined. The traditional place is in system.h but the more logical point for it is in atomic.h - where most architectures (especially new ones) have it defined. These architecture also still offer it via system.h. Some, such as Sparc or s390 only have it in asm/system.h and not available via asm/atomic.h at all. Use the widest set of headers in debug_locks.h and also include asm/system.h. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: "David S.
