While f3761db1 ("x86, irq: Fix build error caused by 9eabc99a") addressed the original build problem, declaration, inline stub, and definition still seem misplaced: It isn't really IO-APIC related, and it's being used solely in arch/x86/pci/. This also means stubbing it out when !CONFIG_X86_IO_APIC was at least questionable. Signed-off-by:

Pull x86 mm tree changes from Ingo Molnar: "The biggest change is full PAT support from Jürgen Gross: The x86 architecture offers via the PAT (Page Attribute Table) a way to specify different caching modes in page table entries. The PAT MSR contains 8 entries each specifying one of 6 possible cache modes. A pte references one of those entries via 3 bits: _PAGE_PAT, _PAGE_PWT and _PAGE_PCD. The Linux kernel currently supports only 4 different cache modes. The PAT MSR is set up in a way that the setting of _PAGE_PAT in a pte doesn't matter: the top 4 entries in the PAT MSR are the same as the 4 lower entries. This results in the kernel not supporting e.g. write-through mode. Especially this cache mode would speed up drivers of video cards which now have to use uncached accesses. OTOH some old processors (Pentium) don't support PAT correctly and the Xen hypervisor has been using a different PAT MSR configuration for some time now and can't change that as this setting is part of the ABI. This patch set abstracts the cache mode from the pte and introduces tables to translate between cache mode and pte bits (the default cache mode "write back" is hard-wired to PAT entry 0). The tables are statically initialized with values being compatible to old processors and current usage. As soon as the PAT MSR is changed (or - in case of Xen - is read at boot time) the tables are changed accordingly. Requests of mappings with special cache modes are always possible now, in case they are not supported there will be a fallback to a compatible but slower mode. Summing it up, this patch set adds the following features: - capability to support WT and WP cache modes on processors with full PAT support - processors with no or uncorrect PAT support are still working as today, even if WT or WP cache mode are selected by drivers for some pages - reduction of Xen special handling regarding cache mode Another change is a boot speedup on ridiculously large RAM systems, plus other smaller fixes" * 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (22 commits) x86: mm: Move PAT only functions to mm/pat.c xen: Support Xen pv-domains using PAT x86: Enable PAT to use cache mode translation tables x86: Respect PAT bit when copying pte values between large and normal pages x86: Support PAT bit in pagetable dump for lower levels x86: Clean up pgtable_types.h x86: Use new cache mode type in memtype related functions x86: Use new cache mode type in mm/ioremap.c x86: Use new cache mode type in setting page attributes x86: Remove looking for setting of _PAGE_PAT_LARGE in pageattr.c x86: Use new cache mode type in track_pfn_remap() and track_pfn_insert() x86: Use new cache mode type in mm/iomap_32.c x86: Use new cache mode type in asm/pgtable.h x86: Use new cache mode type in arch/x86/mm/init_64.c x86: Use new cache mode type in arch/x86/pci x86: Use new cache mode type in drivers/video/fbdev/vermilion x86: Use new cache mode type in drivers/video/fbdev/gbefb.c x86: Use new cache mode type in include/asm/fb.h x86: Make page cache mode a real type x86: mm: Use 2GB memory block size on large-memory x86-64 systems ...

Pull irq domain updates from Thomas Gleixner: "The real interesting irq updates: - Support for hierarchical irq domains: For complex interrupt routing scenarios where more than one interrupt related chip is involved we had no proper representation in the generic interrupt infrastructure so far. That made people implement rather ugly constructs in their nested irq chip implementations. The main offenders are x86 and arm/gic. To distangle that mess we have now hierarchical irqdomains which seperate the various interrupt chips and connect them via the hierarchical domains. That keeps the domain specific details internal to the particular hierarchy level and removes the criss/cross referencing of chip internals. The resulting hierarchy for a complex x86 system will look like this: vector mapped: 74 msi-0 mapped: 2 dmar-ir-1 mapped: 69 ioapic-1 mapped: 4 ioapic-0 mapped: 20 pci-msi-2 mapped: 45 dmar-ir-0 mapped: 3 ioapic-2 mapped: 1 pci-msi-1 mapped: 2 htirq mapped: 0 Neither ioapic nor pci-msi know about the dmar interrupt remapping between themself and the vector domain. If interrupt remapping is disabled ioapic and pci-msi become direct childs of the vector domain. In hindsight we should have done that years ago, but in hindsight we always know better :) - Support for generic MSI interrupt domain handling We have more and more non PCI related MSI interrupts, so providing a generic infrastructure for this is better than having all affected architectures implementing their own private hacks. - Support for PCI-MSI interrupt domain handling, based on the generic MSI support. This part carries the pci/msi branch from Bjorn Helgaas pci tree to avoid a massive conflict. The PCI/MSI parts are acked by Bjorn. I have two more branches on top of this.

I'm such a moron! The simple solution of saving the BSP patch for use on resume was too simple (and wrong!), hint: sizeof(struct microcode_intel). What needs to be done instead is to fish out the microcode patch we have stashed previously and apply that on the BSP in case the late loader hasn't been utilized. So do that instead. Signed-off-by:

Pull scheduler updates from Ingo Molnar: "The main changes in this cycle are: - 'Nested Sleep Debugging', activated when CONFIG_DEBUG_ATOMIC_SLEEP=y. This instruments might_sleep() checks to catch places that nest blocking primitives - such as mutex usage in a wait loop. Such bugs can result in hard to debug races/hangs. Another category of invalid nesting that this facility will detect is the calling of blocking functions from within schedule() -> sched_submit_work() -> blk_schedule_flush_plug(). There's some potential for false positives (if secondary blocking primitives themselves are not ready yet for this facility), but the kernel will warn once about such bugs per bootup, so the warning isn't much of a nuisance. This feature comes with a number of fixes, for problems uncovered with it, so no messages are expected normally. - Another round of sched/numa optimizations and refinements, for CONFIG_NUMA_BALANCING=y. - Another round of sched/dl fixes and refinements.

The branch is the largest one and contains 513 out of the total 972 non-merge arm-soc changesets for 3.19. Most of the changes are about enabling additional on-chip devices for existing machines, but there are also an unusual number of new SoC types being added this time: - AMLogic Meson8 - ARM Realview in DT mode - Allwinner A80 - Broadcom BCM47081 - Broadcom Cygnus - Freescale LS1021A - Freescale Vybrid 500 series - Mediatek MT6592, MT8127, MT8135 - STMicroelectronics STiH410 - Samsung Exynos4415 The level of support for the above differs widely, some are just stubs with nothing more than CPU, memory and a UART, but others are fairly complete.

Pull ARM SoC cleanups from Arnd Bergmann: "The remaining cleanups for 3.19 are to a large part result of devicetree conversion nearing completion on two other platforms besides AT91: - Like AT91, Renesas shmobile is in the process to migrate to DT and multiplatform, but using a different approach of doing it one SoC at a time. For 3.19, the r8a7791 platform and associated "Koelsch" board are considered complete and we remove the non-DT non-multiplatform support for this. - The ARM Versatile Express has supported DT and multiplatform for a long time, but we have still kept the legacy board files around, because not all drivers were fully working before. We have finally taken the last step to remove the board files. Other changes in this branch are preparation for the later branches or just unrelated to the more interesting changes: - The dts files for arm64 get moved into per-vendor directories for a clearer structure. - Some dead code removal (zynq, exynos, davinci, imx) - Using pr_*() macros more consistently instead of printk(KERN_*) in some platform code" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (71 commits) ARM: zynq: Remove secondary_startup() declaration from header ARM: vexpress: Enable regulator framework when MMCI is in use ARM: vexpress: Remove non-DT code ARM: imx: Remove unneeded .map_io initialization ARM: dts: imx6qdl-sabresd: Fix the microphone route ARM: imx: refactor mxc_iomux_mode() ARM: imx: simplify clk_pllv3_prepare() ARM: imx6q: drop unnecessary semicolon ARM: imx: clean up machine mxc_arch_reset_init_dt reset init ARM: dts: imx6qdl-rex: Remove unneeded 'fsl,mode' property ARM: dts: imx6qdl-gw5x: Remove unneeded 'fsl,mode' property ARM: dts: imx6qdl-sabresd: Use IMX6QDL_CLK_CKO define ARM: at91: remove useless init_time for DT-only SoCs ARM: davinci: Remove redundant casts ARM: davinci: Use standard logging styles ARM: shmobile: r8a7779: Spelling/grammar s/entity/identity/, s/map/mapping/ ARM: shmobile: sh7372: Spelling/grammar s/entity map/identity mapping/ ARM: shmobile: sh73a0: Spelling/grammar s/entity map/identity mapping/ ARM: EXYNOS: Remove unused static iomapping ARM: at91: fix build breakage due to legacy board removals ...

Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann: "On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer. All remaining board files that were written in C are dropped, and the ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed altogether. Cleaning up the last pieces was great fun, so I took the time to do some of the coding myself and removed several hundred code lines that ended up unused after the board files were done. There are still a couple of AT91 specific device drivers that are not converted to DT (CF, USB-OTG) and currently not working, and the platform itself is not "multiplatform"-enabled, but both issues are going to be taken care of in the 3.20 cycle.

Pull SCSI updates from James Bottomley: "This patch is the usual mix of driver updates (srp, ipr, scsi_debug, NCR5380, fnic, 53c974, ses, wd719x, hpsa, megaraid_sas). Of those, wd7a9x is new and 53c974 is a rewrite of the old tmscsim driver and the extensive work by Finn Thain rewrites all the NCR5380 based drivers. There's also extensive infrastructure updates: a new logging infrastructure for sense information and a rewrite of the tagged command queue API and an assortment of minor updates" * tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (183 commits) scsi: set fmt to NULL scsi_extd_sense_format() by default libsas: remove task_collector mode wd719x: remove dma_cache_sync call scsi_debug: add Report supported opcodes+tmfs; Compare and write scsi_debug: change SCSI command parser to table driven scsi_debug: add Capacity Changed Unit Attention scsi_debug: append inject error flags onto scsi_cmnd object scsi_debug: pinpoint invalid field in sense data wd719x: Add firmware documentation wd719x: Introduce Western Digital WD7193/7197/7296 PCI SCSI card driver eeprom-93cx6: Add (read-only) support for 8-bit mode esas2r: fix an oversight in setting return value esas2r: fix an error path in esas2r_ioctl_handler esas2r: fir error handling in do_fm_api scsi: add SPC-3 command definitions scsi: rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16 scsi: remove scsi_driver owner field scsi: move scsi_dispatch_cmd to scsi_lib.c scsi: stop passing a gfp_mask argument down the command setup path scsi: remove scsi_next_command ...

Pull device mapper updates from Mike Snitzer: - Significant DM thin-provisioning performance improvements to meet performance requirements that were requested by the Gluster distributed filesystem. Specifically, dm-thinp now takes care to aggregate IO that will be issued to the same thinp block before issuing IO to the underlying devices. This really helps improve performance on HW RAID6 devices that have a writeback cache because it avoids RMW in the HW RAID controller. - Some stable fixes: fix leak in DM bufio if integrity profiles were enabled, use memzero_explicit in DM crypt to avoid any potential for information leak, and a DM cache fix to properly mark a cache block dirty if it was promoted to the cache via the overwrite optimization. - A few simple DM persistent data library fixes - DM cache multiqueue policy block promotion improvements. - DM cache discard improvements that take advantage of range (multiblock) discard support in the DM bio-prison. This allows for much more efficient bulk discard processing (e.g. when mkfs.xfs discards the entire device). - Some small optimizations in DM core and RCU deference cleanups - DM core changes to suspend/resume code to introduce the new internal suspend/resume interface that the DM thin-pool target now uses to suspend/resume active thin devices when the thin-pool must suspend/resume. This avoids forcing userspace to track all active thin volumes in a thin-pool when the thin-pool is suspended for the purposes of metadata or data space resize. * tag 'dm-3.19-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (49 commits) dm crypt: use memzero_explicit for on-stack buffer dm space map metadata: fix sm_bootstrap_get_count() dm space map metadata: fix sm_bootstrap_get_nr_blocks() dm bufio: fix memleak when using a dm_buffer's inline bio dm cache: fix spurious cell_defer when dealing with partial block at end of device dm cache: dirty flag was mistakenly being cleared when promoting via overwrite dm cache: only use overwrite optimisation for promotion when in writeback mode dm cache: discard block size must be a multiple of cache block size dm cache: fix a harmless race when working out if a block is discarded dm cache: when reloading a discard bitset allow for a different discard block size dm cache: fix some issues with the new discard range support dm array: if resizing the array is a noop set the new root to the old one dm: use rcu_dereference_protected instead of rcu_dereference dm thin: fix pool_io_hints to avoid looking at max_hw_sectors dm thin: suspend/resume active thin devices when reloading thin-pool dm: enhance internal suspend and resume interface dm thin: do not allow thin device activation while pool is suspended dm: add presuspend_undo hook to target_type dm: return earlier from dm_blk_ioctl if target doesn't implement .ioctl dm thin: remove stale 'trim' message in block comment above pool_message ...
