Pull ACPI and power management fixes from Rafael Wysocki: - The resume part of user space driven hibernation (s2disk) is now broken after the change that moved the creation of memory bitmaps to after the freezing of tasks, because I forgot that the resume utility loaded the image before freezing tasks and needed the bitmaps for that. The fix adds special handling for that case. - One of recent commits changed the export of acpi_bus_get_device() to EXPORT_SYMBOL_GPL(), which was technically correct but broke existing binary modules using that function including one in particularly widespread use. Change it back to EXPORT_SYMBOL(). - The intel_pstate driver sometimes fails to disable turbo if its no_turbo sysfs attribute is set. Fix from Srinivas Pandruvada. - One of recent cpufreq fixes forgot to update a check in cpufreq-cpu0 which still (incorrectly) treats non-NULL as non-error. Fix from Philipp Zabel. - The SPEAr cpufreq driver uses a wrong variable type in one place preventing it from catching errors returned by one of the functions called by it.

由 Dave Chinner 提交于
The determination of whether a directory entry contains a dtype field originally was dependent on the filesystem having CRCs enabled. This meant that the format for dtype beign enabled could be determined by checking the directory block magic number rather than doing a feature bit check. This was useful in that it meant that we didn't need to pass a struct xfs_mount around to functions that were already supplied with a directory block header. Unfortunately, the introduction of dtype fields into the v4 structure via a feature bit meant this "use the directory block magic number" method of discriminating the dirent entry sizes is broken. Hence we need to convert the places that use magic number checks to use feature bit checks so that they work correctly and not by chance. The current code works on v4 filesystems only because the dirent size roundup covers the extra byte needed by the dtype field in the places where this problem occurs.

When we do a treclaim or trecheckpoint we end up running with userspace PPR and DSCR values. Currently we don't do anything special to avoid running with user values which could cause a severe performance degradation. This patch moves the PPR and DSCR save and restore around treclaim and trecheckpoint so that we run with user values for a much shorter period. More care is taken with the PPR as it's impact is greater than the DSCR. This is similar to user exceptions, where we run HTM_MEDIUM early to ensure that we don't run with a userspace PPR values in the kernel.

Commit 4df48999 "Add power8 EBB support" included a bug in the handling of the FAB_CRESP_MATCH and FAB_TYPE_MATCH fields. These values are pulled out of the event code using EVENT_THR_CTL_SHIFT, however we were then or'ing that value directly into MMCR1. This meant we were failing to set the FAB fields correctly, and also potentially corrupting the value for PMC4SEL. Leading to no counts for the FAB events and incorrect counts for PMC4. The fix is simply to shift left the FAB value correctly before or'ing it with MMCR1.

Under heavy (DLPAR?) stress, we tripped this panic() in arch/powerpc/kernel/iommu.c::iommu_init_table(): page = alloc_pages_node(nid, GFP_ATOMIC, get_order(sz)); if (!page) panic("iommu_init_table: Can't allocate %ld bytes\n", sz); Before the panic() we got a page allocation failure for an order-2 allocation. There appears to be memory free, but perhaps not in the ATOMIC context. I looked through all the call-sites of iommu_init_table() and didn't see any obvious reason to need an ATOMIC allocation. Most call-sites in fact have an explicit GFP_KERNEL allocation shortly before the call to iommu_init_table(), indicating we are not in an atomic context. There is some indirection for some paths, but I didn't see any locks indicating that GFP_KERNEL is inappropriate. With this change under the same conditions, we have not been able to reproduce the panic.

Previous commit 46723bfa... introduced a new config option HAVE_BOOTMEM_INFO_NODE that ended up breaking memory hot-remove for ppc when sparse vmemmap is not defined. This patch defines HAVE_BOOTMEM_INFO_NODE for ppc and adds the call to register_page_bootmem_info_node. Without this we get a BUG_ON for memory hot remove in put_page_bootmem(). This also adds a stub for register_page_bootmem_memmap to allow ppc to build with sparse vmemmap defined. Leaving this as a stub is fine since the same vmemmap addresses are also handled in vmemmap_populate and as such are properly mapped.

IORESOURCE_BUSY is used to mark temporary driver mem-resources instead of global regions. This suppresses warnings if regions overlap with a region marked as BUSY. This was always the case for VESA/VGA/EFI framebuffer regions so do the same for simplefb regions. The reason we do this is to allow device handover to real GPU drivers like i915/radeon/nouveau which get the same regions via PCI BARs. Maybe at some point we will be able to unregister platform devices properly during the handover. In this case the simplefb region would get removed before the new region is created. However, this is currently not the case and would require rather huge changes in remove_conflicting_framebuffers(). Add the BUSY marker now and try to eventually rewrite the handover for a next release. Also see kernel/resource.c for more information: /* * if a resource is "BUSY", it's not a hardware resource * but a driver mapping of such a resource; we don't want * to warn for those; some drivers legitimately map only * partial hardware resources.

Commit ebd97be6 ('PCI: remove ARCH_SUPPORTS_MSI kconfig option') removes the ARCH_SUPPORTS_MSI Kconfig option that allowed architectures to indicate whether they support PCI MSI or not. Now, PCI MSI support can be compiled in on any architecture thanks to the use of weak functions thanks to 4287d824 ('PCI: use weak functions for MSI arch-specific functions'). So, architecture specific code is now responsible to ensure that its PCI MSI code builds in all cases, or be appropriately conditionally compiled. On Sparc, the MSI support is only provided for Sparc64, so the ARCH_SUPPORTS_MSI kconfig option was only selected for SPARC64, and not for the Sparc architecture as a whole. Therefore, removing ARCH_SUPPORTS_MSI broke Sparc32 configurations with CONFIG_PCI_MSI=y, because the Sparc-specific MSI code is not designed to be built on Sparc32. To solve this, this commit ensures that the Sparc MSI code is only built on Sparc64. This is done thanks to a new Kconfig Makefile helper option SPARC64_PCI_MSI, modeled after the existing SPARC64_PCI. The SPARC64_PCI_MSI option is an hidden option that is true when both Sparc64 PCI support is enabled and MSI is enabled. The arch/sparc/kernel/pci_msi.c file is now only built when SPARC64_PCI_MSI is true.

The include/asm-generic/hugetlb.h stubs that just vector huge_pte_*() calls to the pte_*() implementations won't work in certain situations. x86 and sparc, for example, return "unsigned long" from the bit checks, and just go "return pte_val(pte) & PTE_BIT_FOO;" But since huge_pte_*() returns 'int', if any high bits on 64-bit are relevant, they get chopped off. The net effect is that we can loop forever trying to COW a huge page, because the huge_pte_write() check signals false all the time.
