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\nSigned-off-by: Matt Fleming \u003cmatt.fleming@intel.com\u003e\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.

really been fully set up,\nwe really can\u0027t do blocking allocations because with certain (dubious)\nconfigurations the \"might_resched()\" calls can actually result in\nscheduling events.\n\nWe could just make such users always use GFP_ATOMIC, but quite often the\ncode that does the allocation isn\u0027t really aware of the fact that the\nscheduler isn\u0027t up yet, and forcing that kind of random knowledge on the\ninitialization code is just annoying and not good for anybody.\n\nAnd we actually have a the \u0027gfp_allowed_mask\u0027 exactly for this reason:\nit\u0027s just that the kernel init sequence happens to set it to allow\nblocking allocations much too early.\n\nSo move the \u0027gfp_allowed_mask\u0027 initialization from \u0027start_kernel()\u0027\n(which is some of the earliest init code, and runs with preemption\ndisabled for good reasons) into \u0027kernel_init()\u0027. kernel_init() is run\nin the newly created thread that will become the \u0027init\u0027 process, as\nopposed to the early startup code that runs within the context of what\nwill be the first idle thread.\n\nSo by the time we reach \u0027kernel_init()\u0027, we know that the scheduler

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.

Thanks\n Mahesh Salgaonkar.\n\n - The \"EEH\" code (pSeries PCI error handling \u0026 recovery) got a big\n spring cleaning, motivated by the need to be able to implement a\n new backend for it on top of some new different type of firwmare.\n\n The work isn\u0027t complete yet, but a good chunk of the cleanups is\n there. Note that this adds a field to struct device_node which is\n not very nice and which Grant objects to. I will have a patch soon\n that moves that to a powerpc private data structure (hopefully\n before rc1) and we\u0027ll improve things further later on (hopefully\n getting rid of the need for that pointer completely). Thanks Gavin\n Shan.\n\n - I dug into our exception \u0026 interrupt handling code to improve the\n way we do lazy interrupt handling (and make it work properly with\n \"edge\" triggered interrupt sources), and while at it found \u0026 fixed\n a wagon of issues in those areas, including adding support for page\n fault retry \u0026 fatal signals on page faults.\n\n - Your usual random batch of

The delay was longer than the timeouts used in\nthe NFS client during mounting.\n\nNFSROOT worked for Lukas before commit 56463e50 because in those\nkernels, the client\u0027s first operation was an rpcbind request to\ndetermine which port the NFS server was listening on. When that\nrequest failed after a long timeout, the client simply selected the\ndefault NFS port (2049). By that time the switch was allowing access\nto the LAN, and the mount succeeded.\n\nNeither of these client behaviors is desirable, so reverting 56463e50\nis really not a choice. Instead, introduce a mechanism that retries\nthe NFSROOT mount request several times.

The required audit_syscall_exit and\naudit_syscall_entry checks were added to ptrace using the standard\nregisters for system call values (r0 through r3). A thread information\nflag was added for auditing (TIF_SYSCALL_AUDIT) and a meta-flag was\nadded (_TIF_SYSCALL_WORK) to simplify modifications to the syscall\nentry/exit. Now, if either the TRACE flag is set or the AUDIT flag is\nset, the syscall_trace function will be executed. The prober changes\nwere made to Kconfig to allow CONFIG_AUDITSYSCALL to be enabled.\n\nDue to platform availability limitations, this patch was only tested\non the Android platform running the modified \"android-goldfish-2.6.29\"\nkernel.

The delay was longer than the timeouts used in\nthe NFS client during mounting.\n\nNFSROOT worked for Lukas before commit 56463e50 because in those\nkernels, the client\u0027s first operation was an rpcbind request to\ndetermine which port the NFS server was listening on. When that\nrequest failed after a long timeout, the client simply selected the\ndefault NFS port (2049). By that time the switch was allowing access\nto the LAN, and the mount succeeded.\n\nNeither of these client behaviors is desirable, so reverting 56463e50\nis really not a choice. Instead, introduce a mechanism that retries\nthe NFSROOT mount request several times.

Case 2 is less\ndramatic since the earlier fix in this area and also intermittent.\n\n Re: bogomips discrepancy on Intel Core2 Quad CPU -\nhttp://marc.info/?l\u003dlinux-kernel\u0026m\u003d118929277524298\u0026w\u003d4\n slow system and bogus bogomips -\nhttp://marc.info/?l\u003dlinux-kernel\u0026m\u003d116791286716107\u0026w\u003d4\n Re: Re: [RFC-PATCH] clocksource: update lpj if clocksource has -\nhttp://marc.info/?l\u003dlinux-kernel\u0026m\u003d128952775819467\u0026w\u003d4\n\nThis issue is masked a little by commit feae3203d711db0a (\"timers, init:\nLimit the number of per cpu calibration bootup messages\") which only\nprints out the first bogoMIPS value making it much harder to notice other\nvalues differing.
