The memory area for this header is\nalso marked as a separate EFI memory descriptor on ia64.\n\nThe separate EFI memory descriptor is at the moment of the type\nEFI_UNUSABLE_MEMORY. With such a type the secondary kernel skips over the\nentire memory granule (config option, 16M or 64M) when detecting memory.\nIf we are lucky we will just lose some memory, but if we happen to have\ndata in the same granule (such as an initramfs image), then this data will\nnever get mapped and the kernel bombs out when trying to access it.\n\nSo this is an attempt to fix this by changing the EFI memory descriptor\ntype into EFI_LOADER_DATA. This type is the same type used for the kernel\ndata and for initramfs. In the secondary kernel we then handle the ELF\ncore header data the same way as we handle the initramfs image.\n\nThis patch contains the kernel changes to make this happen. Pretty\nstraightforward, we reserve the area in reserve_memory(). The address for\nthe area comes from the kernel command line and the size comes from the\nspecialized EFI parsing function vmcore_find_descriptor_size().\n\nThe kexec-tools-testing code for this can be found here:\nhttp://lists.osdl.org/pipermail/fastboot/2007-February/005983.html\n\nSigned-off-by: Magnus Damm \u003cmagnus@valinux.co.jp\u003e\nCc: Simon Horman \u003chorms@verge.net.au\u003e\nCc: Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "41d5e5d73ecef4ef56b7b4cde962929a712689b4", "tree": "51cb9289609c639d86a768ff92340291a4d1b452", "parents": [ "50157b09b33c2ec3637d3b317b06a7235c57c7f2" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Tue Mar 06 02:34:25 2007 -0800" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Mar 06 14:49:52 2007 -0800" }, "message": "[IA64] permon use-after-free fix\n\nPerfmon associates vmalloc()ed memory with a file descriptor, and installs\na vma mapping that memory.

I think that is caused by the atomic operations\n to clear/set the polling flag in thread_info. There is actually\n no reason to make this atomic - only the idle thread does it\n to itself, other CPUs only read it. So I moved it into ti-\u003estatus.\n\nthe problem is this type of change:\n\n if (!hlt_counter \u0026\u0026 boot_cpu_data.hlt_works_ok) {\n- clear_thread_flag(TIF_POLLING_NRFLAG);\n+ current_thread_info()-\u003estatus \u0026\u003d ~TS_POLLING;\n smp_mb__after_clear_bit();\n while (!need_resched()) {\n local_irq_disable();\n\nthis changes clear_thread_flag() to an explicit clearing of TS_POLLING.\nclear_thread_flag() is defined as:\n\n clear_bit(flag, \u0026ti-\u003eflags);\n\nand clear_bit() is a LOCK-ed atomic instruction on all x86 platforms:\n\n static inline void clear_bit(int nr, volatile unsigned long * addr)\n {\n __asm__ __volatile__( LOCK_PREFIX\n \"btrl %1,%0\"\n\nhence smp_mb__after_clear_bit() is defined as a simple compile barrier:\n\n #define smp_mb__after_clear_bit() barrier()\n\nbut the explicit TS_POLLING clearing introduced by the patch:\n\n+ current_thread_info()-\u003estatus \u0026\u003d ~TS_POLLING;\n\nis not an atomic op! So the clearing of the TS_POLLING bit is freely\nreorderable with the reading of the NEED_RESCHED bit - and both now\nreside in different memory addresses.\n\nCPU idle wakeup very much depends on ordered memory ops, the clearing of\nthe TS_POLLING flag must always be done before we test need_resched()\nand hit the idle instruction(s). [Symmetrically, the wakeup code needs\nto set NEED_RESCHED before it tests the TS_POLLING flag, so memory\nordering is paramount.]\n\nFernando\u0027s dual-core Athlon64 system has a sufficiently advanced memory\nordering model so that it triggered this scenario very often.\n\n( And it also turned out that the reason why these latencies never\n triggered on my testsystems is that i routinely use idle\u003dpoll, which\n was the only idle variant not affected by this bug. )\n\nThe fix is to change the smp_mb__after_clear_bit() to an smp_mb(), to\nact as an absolute barrier between the TS_POLLING write and the\nNEED_RESCHED read. This affects almost all idling methods (default,\nACPI, APM), on all 3 x86 architectures: i386, x86_64, ia64.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nTested-by: Fernando Lopez-Lezcano \u003cnando@ccrma.Stanford.EDU\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "36bcbec7ce21e2e8b3143b11a05747330abeca70", "tree": "d9ace4d83a5013dbb3cd599e7bc4358ce4cdb980", "parents": [ "5b7b4119553dd7cc0bc200c0d1b1598e158eec9a" ], "author": { "name": "Burman Yan", "email": "yan_952@hotmail.com", "time": "Tue Dec 19 12:56:11 2006 -0800" }, "committer": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Wed Dec 20 16:54:54 2006 -0500" }, "message": "ACPI: replace kmalloc+memset with kzalloc\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\n" }, { "commit": "df3e0d1c69c097f54588d720d39efdcdf31e3c24", "tree": "30740405fa706c1f20981f8c8f91fcd261305308", "parents": [ "08ed38b68099f2a492196414b08a7f5dd8dc3537" ], "author": { "name": "bibo,mao", "email": "bibo.mao@intel.com", "time": "Tue Dec 12 12:04:42 2006 -0800" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Dec 12 12:04:42 2006 -0800" }, "message": "[IA64] kprobe clears qp bits for special instructions\n\nOn IA64 there exists some special instructions which\nalways need to be executed regradless of qp bits, such\nas com.crel.unc, tbit.trel.unc etc.\nThis patch clears qp bits when inserting kprobe trap code\nand disables probepoint on slot 1 for these special\ninstructions.\n\nSigned-off-by: bibo,mao \u003cbibo.mao@intel.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "08ed38b68099f2a492196414b08a7f5dd8dc3537", "tree": "1be49040ba10db0fefc16a31c4ee13461c50e131", "parents": [ "75f6a1de41f90543792403bf0ffb3ead59d0d8cc" ], "author": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Nov 14 09:33:38 2006 -0800" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Dec 12 12:00:55 2006 -0800" }, "message": "[IA64] enable trap code on slot 1\n\nBecause slot 1 of one instr bundle crosses border of two consecutive\n8-bytes, kprobe on slot 1 is disabled.

This patch correctly finds the target\nidentifier that triggered the MCA.\n\nIf there are multiple valid cache target identifiers in the same\nerror record then use the one with the lowest cache level.\n\nSigned-off-by: Russ Anderson (rja@sgi.com)\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "5ee7737379b1d7f0c977c0f1661fbaf01a8d4721", "tree": "9a6c4d4a0bf94d5b586e60710a19addda2bcf2b0", "parents": [ "f2454a1a4b2aca38d3b7887619f43291d773c1ee" ], "author": { "name": "Kenji Kaneshige", "email": "kaneshige.kenji@jp.fujitsu.com", "time": "Fri Oct 27 19:49:53 2006 +0900" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Oct 31 14:17:27 2006 -0800" }, "message": "[IA64] cpu-hotplug: Fixing confliction between CPU hot-add and IPI\n\nSigned-off-by: Kenji Kaneshige \u003ckaneshige.kenji@jp.fujitsu.com\u003e\nAcked-by: Satoru Takeuchi \u003ctakeuchi_satoru@jp.fujitsu.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "61ce1efe6e40233663d27ab8ac9ba9710eebcaad", "tree": "782640f26f39b96fbce595883dabbeadb550dd15", "parents": [ "e80391500078b524083ba51c3df01bbaaecc94bb" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Fri Oct 27 11:41:44 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Oct 27 15:34:51 2006 -0700" }, "message": "[PATCH] vmlinux.lds: consolidate initcall sections\n\nAdd a vmlinux.lds.h helper macro for defining the eight-level initcall table,\nteach all the architectures to use it.\n\nThis is a prerequisite for a patch which performs initcall synchronisation for\nmultithreaded-probing.\n\nCc: Greg KH \u003cgreg@kroah.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\n[ Added AVR32 as well ]\nSigned-off-by: Haavard Skinnemoen \u003chskinnemoen@atmel.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9b3377f9921766b6193861d0e3194854b1d765fe", "tree": "3f237114143ceaadb518d0e6967f0c814b785158", "parents": [ "219902677351665bf0513115592a6dd665cf06e8" ], "author": { "name": "Jack Steiner", "email": "steiner@sgi.com", "time": "Mon Oct 16 16:17:43 2006 -0500" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Oct 17 15:03:08 2006 -0700" }, "message": "[IA64] Count resched interrupts\n\nCount the number of \"resched\" interrupts that each cpu receives.\n\nSigned-off-by: Jack Steiner \u003csteiner@sgi.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "219902677351665bf0513115592a6dd665cf06e8", "tree": "3ea3241d377254eb5a5b56a053f30f982c6edc4c", "parents": [ "8611342f3dda0e13970e724129a8e2066de1362e" ], "author": { "name": "Bjorn Helgaas", "email": "bjorn.helgaas@hp.com", "time": "Fri Sep 29 12:58:31 2006 -0600" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Oct 17 14:57:33 2006 -0700" }, "message": "[IA64] remove unused acpi_kbd_controller_present, acpi_legacy_devices\n\nNobody uses either one anymore.\n\nSigned-off-by: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "4d5a31977cc69be8786e0033d5c148e5c62ae949", "tree": "b5f4e16b7da3d1ecf62cc83c975191eb262bdde3", "parents": [ "c12fb1885787dcc2e20c4b88149e1e607e1293b2" ], "author": { "name": "Bjorn Helgaas", "email": "bjorn.helgaas@hp.com", "time": "Thu Oct 12 16:21:17 2006 -0600" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Oct 17 14:54:19 2006 -0700" }, "message": "[IA64] reformat pal.S to fit in 80 columns, fix typos\n\nReformat to fit in 80 columns.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" }, { "commit": "03571e11c4a6d08230657f80970f0a5cc7820471", "tree": "1ee056fff8d00a49f51116932bedf38ea592d038", "parents": [ "3b7d1921f4cdd6d6ddb7899ae7a8d413991c5cf4" ], "author": { "name": "Eric W.
