      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability.  As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n  http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n  only the necessary includes are there.  ie. if only gfp is used,\n  gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n  blocks and try to put the new include such that its order conforms\n  to its surrounding.  It\u0027s put in the include block which contains\n  core kernel includes, in the same order that the rest are ordered -\n  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n  doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n  because the file doesn\u0027t have fitting include block), it prints out\n  an error message indicating which .h file needs to be added to the\n  file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n   over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n   and ~3000 slab.h inclusions.  The script emitted errors for ~400\n   files.\n\n2. Each error was manually checked.  Some didn\u0027t need the inclusion,\n   some needed manual addition while adding it to implementation .h or\n   embedding .c file was more appropriate for others.  This step added\n   inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n   from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n   e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n   APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n   editing them as sprinkling gfp.h and slab.h inclusions around .h\n   files could easily lead to inclusion dependency hell.  Most gfp.h\n   inclusion directives were ignored as stuff from gfp.h was usually\n   wildly available and often used in preprocessor macros.  Each\n   slab.h inclusion directive was examined and added manually as\n   necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my\n   distributed build env didn\u0027t work with gcov compiles) and a few\n   more options had to be turned off depending on archs to make things\n   build (like ipr on powerpc/64 which failed due to missing writeq).\n\n   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n   * powerpc and powerpc64 SMP allmodconfig\n   * sparc and sparc64 SMP allmodconfig\n   * ia64 SMP allmodconfig\n   * s390 SMP allmodconfig\n   * alpha SMP allmodconfig\n   * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n   a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n"

      "message": "xen: implement Xen-specific spinlocks\n\nThe standard ticket spinlocks are very expensive in a virtual\nenvironment, because their performance depends on Xen\u0027s scheduler\ngiving vcpus time in the order that they\u0027re supposed to take the\nspinlock.\n\nThis implements a Xen-specific spinlock, which should be much more\nefficient.\n\nThe fast-path is essentially the old Linux-x86 locks, using a single\nlock byte.  The locker decrements the byte; if the result is 0, then\nthey have the lock.  If the lock is negative, then locker must spin\nuntil the lock is positive again.\n\nWhen there\u0027s contention, the locker spin for 2^16[*] iterations waiting\nto get the lock.  If it fails to get the lock in that time, it adds\nitself to the contention count in the lock and blocks on a per-cpu\nevent channel.\n\nWhen unlocking the spinlock, the locker looks to see if there\u0027s anyone\nblocked waiting for the lock by checking for a non-zero waiter count.\nIf there\u0027s a waiter, it traverses the per-cpu \"lock_spinners\"\nvariable, which contains which lock each CPU is waiting on.  It picks\none CPU waiting on the lock and sends it an event to wake it up.\n\nThis allows efficient fast-path spinlock operation, while allowing\nspinning vcpus to give up their processor time while waiting for a\ncontended lock.\n\n[*] 2^16 iterations is threshold at which 98% locks have been taken\naccording to Thomas Friebel\u0027s Xen Summit talk \"Preventing Guests from\nSpinning Around\".  Therefore, we\u0027d expect the lock and unlock slow\npaths will only be entered 2% of the time.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Christoph Lameter \u003cclameter@linux-foundation.org\u003e\nCc: Petr Tesarik \u003cptesarik@suse.cz\u003e\nCc: Virtualization \u003cvirtualization@lists.linux-foundation.org\u003e\nCc: Xen devel \u003cxen-devel@lists.xensource.com\u003e\nCc: Thomas Friebel \u003cthomas.friebel@amd.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "xen: SMP guest support\n\nThis is a fairly straightforward Xen implementation of smp_ops.\n\nXen has its own IPI mechanisms, and has no dependency on any\nAPIC-based IPI.  The smp_ops hooks and the flush_tlb_others pv_op\nallow a Xen guest to avoid all APIC code in arch/i386 (the only apic\noperation is a single apic_read for the apic version number).\n\nOne subtle point which needs to be addressed is unpinning pagetables\nwhen another cpu may have a lazy tlb reference to the pagetable. Xen\nwill not allow an in-use pagetable to be unpinned, so we must find any\nother cpus with a reference to the pagetable and get them to shoot\ndown their references.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: Benjamin LaHaise \u003cbcrl@kvack.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\n"

      "message": "xen: event channels\n\nXen implements interrupts in terms of event channels.  Each guest\ndomain gets 1024 event channels which can be used for a variety of\npurposes, such as Xen timer events, inter-domain events,\ninter-processor events (IPI) or for real hardware IRQs.\n\nWithin the kernel, we map the event channels to IRQs, and implement\nthe whole interrupt handling using a Xen irq_chip.\n\nRather than setting NR_IRQ to 1024 under PARAVIRT in order to\naccomodate Xen, we create a dynamic mapping between event channels and\nIRQs.  Ideally, Linux will eventually move towards dynamically\nallocating per-irq structures, and we can use a 1:1 mapping between\nevent channels and irqs.\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Eric W.
