(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.

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" }, { "commit": "0013a85454c281faaf064ccb576e373a2881aac8", "tree": "06fc1af0a321631e89ad0f589214e291bd91d19a", "parents": [ "47003497dd819b10874a2291e54df7dc5cf8be57" ], "author": { "name": "Sam Ravnborg", "email": "sam@mars.(none)", "time": "Fri Sep 09 20:57:26 2005 +0200" }, "committer": { "name": "Sam Ravnborg", "email": "sam@mars.(none)", "time": "Fri Sep 09 20:57:26 2005 +0200" }, "message": "kbuild: m68k,parisc,ppc,ppc64,s390,xtensa use generic asm-offsets.h support\n\nDelete obsoleted parts form arch makefiles and rename to asm-offsets.h\n\nSigned-off-by: Sam Ravnborg \u003csam@ravnborg.org\u003e\n" }, { "commit": "951f22d5b1f0eaae35dafc669e3774a0c2084d10", "tree": "66c0131b576dadb98026da11d624df453c4c9a7c", "parents": [ "8449d003f323ca7a00eec38905d984ba5ec83a29" ], "author": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed Jul 27 11:44:57 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Jul 27 16:26:04 2005 -0700" }, "message": "[PATCH] s390: spin lock retry\n\nSplit spin lock and r/w lock implementation into a single try which is done\ninline and an out of line function that repeatedly tries to get the lock\nbefore doing the cpu_relax().
