The {in,out}s{b,w,l} functions are designed to operate on a stream of bytes and therefore should not perform any byte-swapping, regardless of the CPU byte order. This patch fixes the generic IO header so that {in,out}s{b,w,l} call the __raw_{read,write} functions directly rather than going via the endian-correcting accessors.

Since userspace headers were moved to generated/uapi it possible to have a stale copy of linux/version.h at that file's old location. This causes confusion after building an older kernel version, then checking out and building a new one; the old (stale) version header will still get picked up until it is manually removed. This upsets the C library. Since the uapi changes, include/linux/version.h is no longer generated and should not be ignored, so this patch removes it from .gitignore. Signed-off-by:

Currently the __define_initcall() macro takes three arguments, fn, id and level. The level argument is exactly the same as the id argument but wrapped in quotes. To overcome this need to specify three arguments to the __define_initcall macro, where one argument is the stringification of another, we can just use the stringification macro instead.

The branch contains: - The final version of the surprise device removal fixups from Bart. - Don't hide EFI partitions under advanced partition types. It's fairly wide spread these days. This is especially dangerous for systems that have both msdos and efi partition tables, where you want to keep them in sync. - Cleanup of using -1 instead of the proper NUMA_NO_NODE - Export control of bdi flusher thread CPU mask and default to using the home node (if known) from Jeff. - Export unplug tracepoint for MD. - Core improvements from Shaohua. Reinstate the recursive merge, as the original bug has been fixed. Add plugging for discard and also fix a problem handling non pow-of-2 discard limits.

Andrea's autonuma-benchmark numa01 hits kernel BUG at huge_memory.c:1474! in change_huge_pmd called from change_protection from change_prot_numa from task_numa_work. That BUG, introduced in the huge zero page commit cad7f613 ("thp: change_huge_pmd(): make sure we don't try to make a page writable") was trying to verify that newprot never adds write permission to an anonymous huge page; but Automatic NUMA Balancing's 4b10e7d5 ("mm: mempolicy: Implement change_prot_numa() in terms of change_protection()") adds a new prot_numa path into change_huge_pmd(), which makes no use of the newprot provided, and may retain the write bit in the pmd. Just move the BUG_ON(pmd_write(entry)) up into the !prot_numa block. Signed-off-by:

Pull MFS update from Samuel Ortiz: "This is the MFD patch set for the 3.8 merge window. We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts. Many due to __devinit/exit removal, others due to one or two of the new drivers also having come in through another tree. * tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (119 commits) mfd: tps6507x: Convert to devm_kzalloc mfd: stmpe: Update DT support for stmpe driver mfd: wm5102: Add readback of DSP status 3 register mfd: arizona: Log if we fail to create the primary IRQ domain mfd: tps80031: MFD_TPS80031 needs to select REGMAP_IRQ mfd: tps80031: Add terminating entry for tps80031_id_table mfd: sta2x11: Fix potential NULL pointer dereference in __sta2x11_mfd_mask() mfd: wm5102: Add tuning for revision B mfd: arizona: Defer patch initialistation until after first device boot mfd: tps65910: Fix wrong ack_base register mfd: tps65910: Remove unused data mfd: stmpe: Get rid of irq_invert_polarity mfd: ab8500-core: Fix invalid free of devm_ allocated data mfd: wm5102: Mark DSP memory regions as volatile mfd: wm5102: Correct default for LDO1_CONTROL_2 mfd: arizona: Register haptics devices mfd: wm8994: Make current device behaviour the default mfd: tps65090: MFD_TPS65090 needs to select REGMAP_IRQ mfd: Fix stmpe.c build when OF is not enabled mfd: jz4740-adc: Use devm_kzalloc ... -

The first is inline data, which allows small files or directories to be stored in the in-inode extended attribute area. (This requires that the file system use inodes which are at least 256 bytes or larger; 128 byte inodes do not have any room for in-inode xattrs.) The second new feature is SEEK_HOLE/SEEK_DATA support. This is enabled by the extent status tree patches, and this infrastructure will be used to further optimize ext4 in the future.

Pull Automatic NUMA Balancing bare-bones from Mel Gorman: "There are three implementations for NUMA balancing, this tree (balancenuma), numacore which has been developed in tip/master and autonuma which is in aa.git. In almost all respects balancenuma is the dumbest of the three because its main impact is on the VM side with no attempt to be smart about scheduling. In the interest of getting the ball rolling, it would be desirable to see this much merged for 3.8 with the view to building scheduler smarts on top and adapting the VM where required for 3.9. The most recent set of comparisons available from different people are mel: https://lkml.org/lkml/2012/12/9/108 mingo: https://lkml.org/lkml/2012/12/7/331 tglx: https://lkml.org/lkml/2012/12/10/437 srikar: https://lkml.org/lkml/2012/12/10/397 The results are a mixed bag. In my own tests, balancenuma does reasonably well. It's dumb as rocks and does not regress against mainline. On the other hand, Ingo's tests shows that balancenuma is incapable of converging for this workloads driven by perf which is bad but is potentially explained by the lack of scheduler smarts. Thomas' results show balancenuma improves on mainline but falls far short of numacore or autonuma. Srikar's results indicate we all suffer on a large machine with imbalanced node sizes. My own testing showed that recent numacore results have improved dramatically, particularly in the last week but not universally. We've butted heads heavily on system CPU usage and high levels of migration even when it shows that overall performance is better. There are also cases where it regresses. Of interest is that for specjbb in some configurations it will regress for lower numbers of warehouses and show gains for higher numbers which is not reported by the tool by default and sometimes missed in treports. Recently I reported for numacore that the JVM was crashing with NullPointerExceptions but currently it's unclear what the source of this problem is. Initially I thought it was in how numacore batch handles PTEs but I'm no longer think this is the case. It's possible numacore is just able to trigger it due to higher rates of migration. These reports were quite late in the cycle so I/we would like to start with this tree as it contains much of the code we can agree on and has not changed significantly over the last 2-3 weeks." * tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma: (50 commits) mm/rmap, migration: Make rmap_walk_anon() and try_to_unmap_anon() more scalable mm/rmap: Convert the struct anon_vma::mutex to an rwsem mm: migrate: Account a transhuge page properly when rate limiting mm: numa: Account for failed allocations and isolations as migration failures mm: numa: Add THP migration for the NUMA working set scanning fault case build fix mm: numa: Add THP migration for the NUMA working set scanning fault case. mm: sched: numa: Delay PTE scanning until a task is scheduled on a new node mm: sched: numa: Control enabling and disabling of NUMA balancing if !SCHED_DEBUG mm: sched: numa: Control enabling and disabling of NUMA balancing mm: sched: Adapt the scanning rate if a NUMA hinting fault does not migrate mm: numa: Use a two-stage filter to restrict pages being migrated for unlikely task<->node relationships mm: numa: migrate: Set last_nid on newly allocated page mm: numa: split_huge_page: Transfer last_nid on tail page mm: numa: Introduce last_nid to the page frame sched: numa: Slowly increase the scanning period as NUMA faults are handled mm: numa: Rate limit setting of pte_numa if node is saturated mm: numa: Rate limit the amount of memory that is migrated between nodes mm: numa: Structures for Migrate On Fault per NUMA migration rate limiting mm: numa: Migrate pages handled during a pmd_numa hinting fault mm: numa: Migrate on reference policy ... -

This reverts commit bd52276f ("x86-64/efi: Use EFI to deal with platform wall clock (again)"), and the two supporting commits: da5a108d: "x86/kernel: remove tboot 1:1 page table creation code" 185034e7: "x86, efi: 1:1 pagetable mapping for virtual EFI calls") as they all depend semantically on commit 53b87cf0 ("x86, mm: Include the entire kernel memory map in trampoline_pgd") that got reverted earlier due to the problems it caused. This was pointed out by Yinghai Lu, and verified by me on my Macbook Air that uses EFI. Pointed-out-by:

Pull target updates from Nicholas Bellinger: "It has been a very busy development cycle this time around in target land, with the highlights including: - Kill struct se_subsystem_dev, in favor of direct se_device usage (hch) - Simplify reservations code by combining SPC-3 + SCSI-2 support for virtual backends only (hch) - Simplify ALUA code for virtual only backends, and remove left over abstractions (hch) - Pass sense_reason_t as return value for I/O submission path (hch) - Refactor MODE_SENSE emulation to allow for easier addition of new mode pages. (roland) - Add emulation of MODE_SELECT (roland) - Fix bug in handling of ExpStatSN wrap-around (steve) - Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve) - Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab) - Convert ib_srpt to use modern target_submit_cmd caller + drop legacy ioctx->kref usage (nab) - Convert ib_srpt to use modern target_submit_tmr caller (nab) - Add link_magic for fabric allow_link destination target_items for symlinks within target_core_fabric_configfs.c code (nab) - Allocate pointers in instead of full structs for config_group->default_groups (sebastian) - Fix 32-bit highmem breakage for FILEIO (sebastian) All told, hch was able to shave off another ~1K LOC by killing the se_subsystem_dev abstraction, along with a number of PR + ALUA simplifications. Also, a nice patch by Roland is the refactoring of MODE_SENSE handling, along with the addition of initial MODE_SELECT emulation support for virtual backends. Sebastian found a long-standing issue wrt to allocation of full config_group instead of pointers for config_group->default_group[] setup in a number of areas, which ends up saving memory with big configurations. He also managed to fix another long-standing BUG wrt to broken 32-bit highmem support within the FILEIO backend driver.
