However, I\nthink that the approach in this patch is a much more robust idea.\n\nAcked-by: Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\nSigned-off-by: Simon Horman \u003chorms@verge.net.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "1eeb66a1bb973534dc3d064920a5ca683823372e", "tree": "19c22d611e6adefb352dbc107b859e4d13ba38c1", "parents": [ "e3869792990f708c97be5877499cada70d469bd3" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Tue May 08 00:27:03 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:04 2007 -0700" }, "message": "move die notifier handling to common code\n\nThis patch moves the die notifier handling to common code.

It is the responsibility of system software to\ninitialize and maintain MTRR consistency across all processors.\"\n\nCurrent Linux MTRR code already implements the above in the case that the\nBIOS does not properly initialize MTRRs on the secondary processors,\nbut the case where the fixed-range MTRRs of the boot processor are changed\nafter Linux started to boot, before the initialsation of a secondary\nprocessor, is not handled yet.\n\nIn this case, secondary processors are currently initialized by Linux\nwith MTRRs which the boot processor had very early, when mtrr_bp_init()\ndid run, but not with the MTRRs which the boot processor uses at the\ntime when that secondary processors is actually booted,\ncausing differing MTRR contents on the secondary processors.\n\nSuch situation happens on Acer Ferrari 1000 and 5000 notebooks where the\nBIOS enables and sets AMD-specific IORR bits in the fixed-range MTRRs\nof the boot processor when it transitions the system into ACPI mode.\nThe SMI handler of the BIOS does this in SMM, entered while Linux ACPI\ncode runs acpi_enable().\n\nOther occasions where the SMI handler of the BIOS may change bits in\nthe MTRRs could occur as well. To initialize newly booted secodary\nprocessors with the fixed-range MTRRs which the boot processor uses\nat that time, this patch saves the fixed-range MTRRs of the boot\nprocessor before new secondary processors are started. When the\nsecondary processors run their Linux initialisation code, their\nfixed-range MTRRs will be updated with the saved fixed-range MTRRs.\n\nIf CONFIG_MTRR is not set, we define mtrr_save_state\nas an empty statement because there is nothing to do.\n\nPossible TODOs:\n\n*) CPU-hotplugging outside of SMP suspend/resume is not yet tested\n with this patch.\n\n*) If, even in this case, an AP never runs i386/do_boot_cpu or x86_64/cpu_up,\n then the calls to mtrr_save_state() could be replaced by calls to\n mtrr_save_fixed_ranges(NULL) and mtrr_save_state() would not be\n needed.\n\n That would need either verification of the CPU-hotplug code or\n at least a test on a \u003e2 CPU machine.\n\n*) The MTRRs of other running processors are not yet checked at this\n time but it might be interesting to syncronize the MTTRs of all\n processors before booting. That would be an incremental patch,\n but of rather low priority since there is no machine known so\n far which would require this.\n\nAK: moved prototypes on x86-64 around to fix warnings\n\nSigned-off-by: Bernhard Kaindl \u003cbk@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Dave Jones \u003cdavej@codemonkey.org.uk\u003e\n" }, { "commit": "2b3b4835c94226681c496de9446d456dcf42ed08", "tree": "a7f005ccb038107153059691dbabf048b560521d", "parents": [ "856f44ff4af6e57fdc39a8b2bec498c88438bd27" ], "author": { "name": "Bernhard Kaindl", "email": "bk@suse.de", "time": "Wed May 02 19:27:17 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:17 2007 +0200" }, "message": "[PATCH] x86: Adds mtrr_save_fixed_ranges() for use in two later patches.\n\nIn this current implementation which is used in other patches,\nmtrr_save_fixed_ranges() accepts a dummy void pointer because\nin the current implementation of one of these patches, this\nfunction may be called from smp_call_function_single() which\nrequires that this function takes a void pointer argument.\n\nThis function calls get_fixed_ranges(), passing mtrr_state.fixed_ranges\nwhich is the element of the static struct which stores our current\nbackup of the fixed-range MTRR values which all CPUs shall be\nusing.\n\nBecause mtrr_save_fixed_ranges calls get_fixed_ranges after\nkernel initialisation time, __init needs to be removed from\nthe declaration of get_fixed_ranges().\n\nIf CONFIG_MTRR is not set, we define mtrr_save_fixed_ranges\nas an empty statement because there is nothing to do.\n\nAK: Moved prototypes for x86-64 around to fix warnings\n\nSigned-off-by: Bernhard Kaindl \u003cbk@suse.de\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Dave Jones \u003cdavej@codemonkey.org.uk\u003e\n" }, { "commit": "856f44ff4af6e57fdc39a8b2bec498c88438bd27", "tree": "475ca01f27c3272ec9e3d15f3d8209ad4424c3bc", "parents": [ "03df4f6ee997589a84d5f9492c6419183724c710" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Wed May 02 19:27:17 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:17 2007 +0200" }, "message": "[PATCH] x86-64: Move mtrr prototypes from proto.h to mtrr.h\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "441d40dca024deb305a5e3d5003e8cd9d364d10f", "tree": "e6836e5e325aa717bca9fab4fa188b64a979261a", "parents": [ "e0bb8643974397a8d36670e06e6a54bb84f3289f" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Wed May 02 19:27:16 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:16 2007 +0200" }, "message": "[PATCH] x86: PARAVIRT: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\n\nThe other symbols used to delineate the alt-instructions sections have the\nform __foo/__foo_end.

These nodes are then dynamically allocated and their\nborders extended until such time as their number of available pages reaches\nthe required size.\n\nConfigurable node sizes are recommended when used in conjunction with cpusets\nfor memory control because it eliminates the overhead associated with scanning\nthe zonelists of many smaller full nodes on page_alloc().\n\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Paul Jackson \u003cpj@sgi.com\u003e\nCc: Christoph Lameter \u003cclameter@engr.sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n" }, { "commit": "5a90cf205c922707ffed2d8f87cefd942e96b0ba", "tree": "5e9c9c1be3d149bff7620db89e1ede2317ba7362", "parents": [ "2714221985ce6388ec2fa78d7d52e2a5bef78eec" ], "author": { "name": "john stultz", "email": "johnstul@us.ibm.com", "time": "Wed May 02 19:27:08 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:08 2007 +0200" }, "message": "[PATCH] x86: Log reason why TSC was marked unstable\n\nChange mark_tsc_unstable() so it takes a string argument, which holds the\nreason the TSC was marked unstable.\n\nThis is then displayed the first time mark_tsc_unstable is called.\n\nThis should help us better debug why the TSC was marked unstable on certain\nsystems and allow us to make sure we\u0027re not being overly paranoid when\nthrowing out this troublesome clocksource.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "6a50a664ca0cfd2a487525f10cec3ff4d570b5e8", "tree": "cf68fae284a7b44df616a8112e9088557ad31d76", "parents": [ "1ab60e0f72f71ec54831e525a3e1154f1c092408" ], "author": { "name": "Vivek Goyal", "email": "vgoyal@in.ibm.com", "time": "Wed May 02 19:27:08 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:08 2007 +0200" }, "message": "[PATCH] x86-64: build-time checking\n\no X86_64 kernel should run from 2MB aligned address for two reasons.\n\t- Performance.\n\t- For relocatable kernels, page tables are updated based on difference\n\t between compile time address and load time physical address.\n\t This difference should be multiple of 2MB as kernel text and data\n\t is mapped using 2MB pages and PMD should be pointing to a 2MB\n\t aligned address.

Then we enable clocksource selection at late_initcall time. This\ncauses some problems for drivers that use gettimeofday for init\ncalibration routines (specifically the es1968 driver in this case),\nwhere durring module_init, the only clocksource available is the low-res\njiffies clocksource. This may cause slight calibration errors, due to\nthe small sampling time used.\n\nIt should be noted that drivers that require fine grained time may not\nfunction on architectures that do not have better then jiffies\nresolution timekeeping (there are a few). However, this does not\ndiscount the reasonable need for such fine-grained timekeeping at init\ntime.\n\nThus the solution here is to register clocksources earlier (ideally when\nthe hardware is being initialized), and then we enable clocksource\nselection at fs_initcall (before device_initcall).\n\nThis patch should probably get some testing time in -mm, since\nclocksource selection is one of the most important issues for correct\ntimekeeping, and I\u0027ve only been able to test this on a few of my own\nboxes.\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"David S.
