       "Here are a few powerpc fixes, all aimed at -stable, found in part
        thanks to the ramping up of a major distro testing and in part thanks
        to the LE guys hitting all sort interesting corner cases.
      
        The most scary are probably the register clobber issues in
        csum_partial_copy_generic(), especially since Anton even had a test
        case for that thing, which didn't manage to hit the bugs :-)
      
        Another highlight is that memory hotplug should work again with these
        fixes.
      
        Oh and the vio modalias one is worse than the cset implies as it
        upsets distro installers, so I've been told at least, which is why I'm
        shooting it to stable"

      powerpc/tm: Switch out userspace PPR and DSCR sooner · e9bdc3d6
      Michael Neuling authored
      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.

      powerpc/perf: Fix handling of FAB events · a53b27b3
      Michael Ellerman authored
      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.

      powerpc/iommu: Use GFP_KERNEL instead of GFP_ATOMIC in iommu_init_table() · 1cf389df
      Nishanth Aravamudan authored
      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.

      powerpc: Restore registers on error exit from csum_partial_copy_generic() · 8f21bd00
      Paul E. McKenney authored
      The csum_partial_copy_generic() function saves the PowerPC non-volatile
      r14, r15, and r16 registers for the main checksum-and-copy loop.
      Unfortunately, it fails to restore them upon error exit from this loop,
      which results in silent corruption of these registers in the presumably
      rare event of an access exception within that loop.
      
      This commit therefore restores these register on error exit from the loop.

      powerpc: Fix parameter clobber in csum_partial_copy_generic() · d9813c36
      Paul E. McKenney authored
      The csum_partial_copy_generic() uses register r7 to adjust the remaining
      bytes to process.  Unfortunately, r7 also holds a parameter, namely the
      address of the flag to set in case of access exceptions while reading
      the source buffer.  Lacking a quantum implementation of PowerPC, this
      commit instead uses register r9 to do the adjusting, leaving r7's
      pointer uncorrupted.

      powerpc: Fix memory hotplug with sparse vmemmap · f7e3334a
      Nathan Fontenot authored
      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.

      x86/simplefb: Mark framebuffer mem-resources as IORESOURCE_BUSY to avoid bootup warning · 29d274b8
      David Herrmann authored
      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. (example: vesafb)
         */
      
      This suppresses warnings like:
      
        ------------[ cut here ]------------

       "We have a fairly large batch of fixes this time around, mostly just
        due to various platforms all having a fix or two more than usual.
      
        Worth pointing out are:
      
         - A fix for EDMA on Davinci/OMAP where channel allocation broke with
           the DT conversion.  Due to some miscommunication we didn't
           understand the impact of the breakage, so we were pushing back on
           it for 3.12, but it sounds like it's actually breaking quite a few
           people out there.
      
         - A bunch of fixes for Marvell platforms, some straggling fixes for
           merge window fallout and some fixes for a couple of the platforms
           (Netgear RN102 in particular).
      
         - A fix for a race between multi-cluster power management and cpu
           hotplug on Versatile Express.
      
        And a bunch of other smaller fixes that all add up.

      ARC: Fix signal frame management for SA_SIGINFO · 10469350
      Christian Ruppert authored
      Previously, when a signal was registered with SA_SIGINFO, parameters 2
      and 3 of the signal handler were written to registers r1 and r2 before
      the register set was saved. This led to corruption of these two
      registers after returning from the signal handler (the wrong values were
      restored).
      With this patch, registers are now saved before any parameters are
      passed, thus maintaining the processor state from before signal entry.

      sparc: fix MSI build failure on Sparc32 · a988fb80
      Thomas Petazzoni authored
      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

      mm: Fix generic hugetlb pte check return type. · 26794942
      David Miller authored
      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.

      sparc: fix ldom_reboot buffer overflow harder · 20928bd3
      Kees Cook authored
      The length argument to strlcpy was still wrong. It could overflow the end of
      full_boot_str by 5 bytes. Instead of strcat and strlcpy, just use snprint.

      Freeing ->s_{inode,dentry}_lru in deactivate_locked_super() is wrong;
      the right place is destroy_super().  As it is, we leak them if sget()
      decides that new superblock it has allocated (and never shown to
      anybody) isn't needed and should be freed.
