It does the following\nthings:\n\n - consolidates and enhances the spinlock/rwlock debugging code\n\n - simplifies the asm/spinlock.h files\n\n - encapsulates the raw spinlock type and moves generic spinlock\n features (such as -\u003ebreak_lock) into the generic code.\n\n - cleans up the spinlock code hierarchy to get rid of the spaghetti.\n\nMost notably there\u0027s now only a single variant of the debugging code,\nlocated in lib/spinlock_debug.c. (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. The new layout is:\n\n SMP | UP\n ----------------------------|-----------------------------------\n asm/spinlock_types_smp.h | linux/spinlock_types_up.h\n linux/spinlock_types.h | linux/spinlock_types.h\n asm/spinlock_smp.h | linux/spinlock_up.h\n linux/spinlock_api_smp.h | linux/spinlock_api_up.h\n linux/spinlock.h | linux/spinlock.h\n\n/*\n * here\u0027s the role of the various spinlock/rwlock related include files:\n *\n * on SMP builds:\n *\n * asm/spinlock_types.h: contains the raw_spinlock_t/raw_rwlock_t and the\n * initializers\n *\n * linux/spinlock_types.h:\n * defines the generic type and initializers\n *\n * asm/spinlock.h: contains the __raw_spin_*()/etc. lowlevel\n * implementations, mostly inline assembly code\n *\n * (also included on UP-debug builds:)\n *\n * linux/spinlock_api_smp.h:\n * contains the prototypes for the _spin_*() APIs.\n *\n * linux/spinlock.h: builds the final spin_*() APIs.\n *\n * on UP builds:\n *\n * linux/spinlock_type_up.h:\n * contains the generic, simplified UP spinlock type.\n * (which is an empty structure on non-debug builds)\n *\n * linux/spinlock_types.h:\n * defines the generic type and initializers\n *\n * linux/spinlock_up.h:\n * contains the __raw_spin_*()/etc. version of UP\n * builds.

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" } ] }
