Over time its semantics have changed, and it now\nindicates whether or not we are booted on an EFI machine with\nbit-native firmware, e.g. 64-bit kernel with 64-bit firmware.\n\nThe immediate motivation for this patch is the bug report at,\n\n https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557\n\nwhich details how running a platform driver on an EFI machine that is\ndesigned to run under BIOS can cause the machine to become\nbricked. Also, the following report,\n\n https://bugzilla.kernel.org/show_bug.cgi?id\u003d47121\n\ndetails how running said driver can also cause Machine Check\nExceptions. Drivers need a new means of detecting whether they\u0027re\nrunning on an EFI machine, as sadly the expression,\n\n if (!efi_enabled)\n\nhasn\u0027t been a sufficient condition for quite some time.\n\nUsers actually want to query \u0027efi_enabled\u0027 for different reasons -\nwhat they really want access to is the list of available EFI\nfacilities.\n\nFor instance, the x86 reboot code needs to know whether it can invoke\nthe ResetSystem() function provided by the EFI runtime services, while\nthe ACPI OSL code wants to know whether the EFI config tables were\nmapped successfully. There are also checks in some of the platform\ndriver code to simply see if they\u0027re running on an EFI machine (which\nwould make it a bad idea to do BIOS-y things).\n\nThis patch is a prereq for the samsung-laptop fix patch.\n\nCc: David Airlie \u003cairlied@linux.ie\u003e\nCc: Corentin Chary \u003ccorentincj@iksaif.net\u003e\nCc: Matthew Garrett \u003cmjg59@srcf.ucam.org\u003e\nCc: Dave Jiang \u003cdave.jiang@intel.com\u003e\nCc: Olof Johansson \u003colof@lixom.net\u003e\nCc: Peter Jones \u003cpjones@redhat.com\u003e\nCc: Colin Ian King \u003ccolin.king@canonical.com\u003e\nCc: Steve Langasek \u003csteve.langasek@canonical.com\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: Konrad Rzeszutek Wilk \u003ckonrad@kernel.org\u003e\nCc: Rafael J.

Now the ignore_unknown_bootoption() is the last\none to run, and it wasn\u0027t doing the necessary repair, so the\nenvp params ended up with the embedded NUL and were no longer\nseen as valid environment variables by init.\n\nTested-by: Woody Suwalski \u003cterraluna977@gmail.com\u003e\nAcked-by: Pawel Moll \u003cpawel.moll@arm.com\u003e\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "0195c00244dc2e9f522475868fa278c473ba7339", "tree": "f97ca98ae64ede2c33ad3de05ed7bbfa4f4495ed", "parents": [ "f21ce8f8447c8be8847dadcfdbcc76b0d7365fa5", "141124c02059eee9dbc5c86ea797b1ca888e77f7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 28 15:58:21 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 28 15:58:21 2012 -0700" }, "message": "Merge tag \u0027split-asm_system_h-for-linus-20120328\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system\n\nPull \"Disintegrate and delete asm/system.h\" from David Howells:\n \"Here are a bunch of patches to disintegrate asm/system.h into a set of\n separate bits to relieve the problem of circular inclusion\n dependencies.\n\n I\u0027ve built all the working defconfigs from all the arches that I can\n and made sure that they don\u0027t break.\n\n The reason for these patches is that I recently encountered a circular\n dependency problem that came about when I produced some patches to\n optimise get_order() by rewriting it to use ilog2().\n\n This uses bitops - and on the SH arch asm/bitops.h drags in\n asm-generic/get_order.h by a circuituous route involving asm/system.h.\n\n The main difficulty seems to be asm/system.h. It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

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" }, { "commit": "5ab116c9349ef52d6fbd2e2917a53f13194b048e", "tree": "636a6cf02d5ca47c6da5d4935b07ddf08666a09c", "parents": [ "5574169613b40b85d6f4c67208fa4846b897a0a1" ], "author": { "name": "Miao Xie", "email": "miaox@cn.fujitsu.com", "time": "Tue Mar 23 13:35:34 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 24 16:31:21 2010 -0700" }, "message": "cpuset: fix the problem that cpuset_mem_spread_node() returns an offline node\n\ncpuset_mem_spread_node() returns an offline node, and causes an oops.\n\nThis patch fixes it by initializing task-\u003emems_allowed to\nnode_states[N_HIGH_MEMORY], and updating task-\u003emems_allowed when doing\nmemory hotplug.\n\nSigned-off-by: Miao Xie \u003cmiaox@cn.fujitsu.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nReported-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nTested-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7463e633c5f94792dcff1afefb0d2961318a9d09", "tree": "db2ee59033f50dfe2b3ebe48c08cefef86720bc8", "parents": [ "cfd8d6c0ed89ba387609419e3d8d4c6b92a5d446" ], "author": { "name": "H Hartley Sweeten", "email": "hartleys@visionengravers.com", "time": "Fri Mar 05 13:42:46 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:32 2010 -0800" }, "message": "init/main.c: make setup_max_cpus static for !SMP\n\nThe only in tree external users of the symbol setup_max_cpus are in\narch/x86/.
