This shift has caused a whole bunch of\ncompile problems under different config options. I attempt to\nsimplify things with the patch below.\n\nIn order to simplify things, I had to come to terms with the\nmeaning of two terms ARCH_HAS_NMI_WATCHDOG and\nCONFIG_HARDLOCKUP_DETECTOR. Basically they mean the same thing,\nthe former on a local level and the latter on a global level.\n\nWith the old x86 nmi watchdog gone, there is no need to rely on\ndefining the ARCH_HAS_NMI_WATCHDOG variable because it doesn\u0027t\nmake sense any more. x86 will now use the global\nimplementation.\n\nThe changes below do a few things. First it changes the few\nplaces that relied on ARCH_HAS_NMI_WATCHDOG to use\nCONFIG_X86_LOCAL_APIC (the former was an alias for the latter\nanyway, so nothing unusual here). Those pieces of code were\nrelying more on local apic functionality the nmi watchdog\nfunctionality, so the change should make sense.\n\nSecond, I removed the x86 implementation of\ntouch_nmi_watchdog(). It isn\u0027t need now, instead x86 will rely\non kernel/watchdog.c\u0027s implementation.\n\nThird, I removed the #define ARCH_HAS_NMI_WATCHDOG itself from\nx86. And tweaked the include/linux/nmi.h file to tell users to\nlook for an externally defined touch_nmi_watchdog in the case of\nARCH_HAS_NMI_WATCHDOG _or_ CONFIG_HARDLOCKUP_DETECTOR. This\nchanges removes some of the ugliness in that file.\n\nFinally, I added a Kconfig dependency for\nCONFIG_HARDLOCKUP_DETECTOR that said you can\u0027t have\nARCH_HAS_NMI_WATCHDOG _and_ CONFIG_HARDLOCKUP_DETECTOR. You can\nonly have one nmi_watchdog.\n\nTested with\nARCH\u003di386: allnoconfig, defconfig, allyesconfig, (various broken\nconfigs) ARCH\u003dx86_64: allnoconfig, defconfig, allyesconfig,\n(various broken configs)\n\nHopefully, after this patch I won\u0027t get any more compile broken\nemails. :-)\n\nv3:\n changed a couple of \u0027linux/nmi.h\u0027 -\u003e \u0027asm/nmi.h\u0027 to pick-up correct function\n prototypes when CONFIG_HARDLOCKUP_DETECTOR is not set.\n\nSigned-off-by: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: fweisbec@gmail.com\nLKML-Reference: \u003c1293044403-14117-1-git-send-email-dzickus@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "4b7bd364700d9ac8372eff48832062b936d0793b", "tree": "0dbf78c95456a0b02d07fcd473281f04a87e266d", "parents": [ "c0d8768af260e2cbb4bf659ae6094a262c86b085", "90a8a73c06cc32b609a880d48449d7083327e11a" ], "author": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Wed Dec 22 18:57:02 2010 +0100" }, "committer": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Wed Dec 22 18:57:02 2010 +0100" }, "message": "Merge branch \u0027master\u0027 into for-next\n\nConflicts:\n\tMAINTAINERS\n\tarch/arm/mach-omap2/pm24xx.c\n\tdrivers/scsi/bfa/bfa_fcpim.c\n\nNeeded to update to apply fixes for which the old branch was too\noutdated.\n" }, { "commit": "819a72af8d6653daa48334f24ce0a935ccdd33c7", "tree": "d834c9c7c66821d08ec965aab04d0c9ded263085", "parents": [ "e72df0b847adf064e64bcbd5141f0031524e723e" ], "author": { "name": "Christoph Lameter", "email": "cl@linux.com", "time": "Mon Dec 06 11:16:19 2010 -0600" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Fri Dec 17 15:07:18 2010 +0100" }, "message": "percpucounter: Optimize __percpu_counter_add a bit through the use of this_cpu() options.\n\nThe this_cpu_* options can be used to optimize __percpu_counter_add a bit.
