Defined\n by every SMP architecture in include/asm-*/smp.h.\n\nThere is one new internal symbol, dependent on DEBUG_PREEMPT:\n\n - debug_smp_processor_id(): internal debug variant, mapped to\n smp_processor_id().\n\nAlso, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new\nlib/smp_processor_id.c file. All related comments got updated and/or\nclarified.\n\nI have build/boot tested the following 8 .config combinations on x86:\n\n {SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT}\n\nI have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT. (Other\narchitectures are untested, but should work just fine.)\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
