(previously we had one SMP debugging\nvariant per architecture, plus a separate generic one for UP builds)\n\nAlso, i\u0027ve enhanced the rwlock debugging facility, it will now track\nwrite-owners.  There is new spinlock-owner/CPU-tracking on SMP builds too.\nAll locks have lockup detection now, which will work for both soft and hard\nspin/rwlock lockups.\n\nThe arch-level include files now only contain the minimally necessary\nsubset of the spinlock code - all the rest that can be generalized now\nlives in the generic headers:\n\n include/asm-i386/spinlock_types.h       |   16\n include/asm-x86_64/spinlock_types.h     |   16\n\nI have also split up the various spinlock variants into separate files,\nmaking it easier to see which does what.

I did not try to build\n  non-SMP kernels.  That should be trivial to fix up later if necessary.\n\n  I converted bit ops atomic_hash lock to raw_spinlock_t.  Doing so avoids\n  some ugly nesting of linux/*.h and asm/*.h files.  Those particular locks\n  are well tested and contained entirely inside arch specific code.  I do NOT\n  expect any new issues to arise with them.\n\n If someone does ever need to use debug/metrics with them, then they will\n  need to unravel this hairball between spinlocks, atomic ops, and bit ops\n  that exist only because parisc has exactly one atomic instruction: LDCW\n  (load and clear word).\n\nFrom: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\n\n   ia64 fix\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjanv@infradead.org\u003e\nSigned-off-by: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nSigned-off-by: Mikael Pettersson \u003cmikpe@csd.uu.se\u003e\nSigned-off-by: Benoit Boissinot \u003cbenoit.boissinot@ens-lyon.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
