      parisc: Remove arch/parisc/kernel/sys32.h header · 5a0ce2dc
      John David Anglin authored
      The KERNEL_SYSCALL define is not used anymore so the header can be
      removed.

      parisc: agp/parisc-agp: allow binding of user memory to the AGP GART · 06f0cce4
      Alex Ivanov authored
      Allow binding of user memory to the AGP GART on systems with HP
      Quicksilver AGP bus. This resolves 'bind memory failed' error seen in
      dmesg:
      
       [29.365973] [TTM] AGP Bind memory failed.
       …
       [29.367030] [drm] Forcing AGP to PCI mode
      
      The system doesn't more fail to bind the memory, and hence not falling
      back to the PCI mode (if other failures aren't detected).
      
      This is just a simple write down from the following patches:
      agp/amd-k7: Allow binding user memory to the AGP GART
      agp/hp-agp: Allow binding user memory to the AGP GART

      parisc: Fix cache routines to ignore vma's with an invalid pfn · 50861f5a
      John David Anglin authored
      The parisc architecture does not have a pte special bit. As a result,
      special mappings are handled with the VM_PFNMAP and VM_MIXEDMAP flags.
      VM_MIXEDMAP mappings may or may not have a "struct page" backing. When
      pfn_valid() is false, there is no "struct page" backing. Otherwise, they
      are treated as normal pages.
      
      The FireGL driver uses the VM_MIXEDMAP without a backing "struct page".
      This treatment caused a panic due to a TLB data miss in
      update_mmu_cache. This appeared to be in the code generated for
      page_address(). We were in fact using a very circular bit of code to
      determine the physical address of the PFN in various cache routines.
      This wasn't valid when there was no "struct page" backing.  The needed
      address can in fact be determined simply from the PFN itself without
      using the "struct page".
      
      The attached patch updates update_mmu_cache(), flush_cache_mm(),
      flush_cache_range() and flush_cache_page() to check pfn_valid() and to
      directly compute the PFN physical and virtual addresses.

      mvneta: Try to fix mvneta when compiled as module · 5445eaf3
      Arnaud Patard \(Rtp\) authored
      When the mvneta driver is compiled as module, the clock is disabled before
      it's loading. This will reset the registers values and all configuration
      made by the bootloader.
      
      This patch sets the "sgmii serdes configuration" register to a magical value
      found in:
      https://github.com/yellowback/ubuntu-precise-armadaxp/blob/master/arch/arm/mach-armadaxp/armada_xp_family/ctrlEnv/mvCtrlEnvLib.c
      
      With this change, the interrupts are working/generated and ethernet is

      Arnaud Patard \(Rtp\) authored
      When the mvneta driver is compiled, it'll be loaded with clocks disabled.
      This implies that the clocks should be enabled again before any register
      access or it'll hang.
      
      To fix it:
      - enable clock earlier
      - move timer callback after setting timer.data

      Please try the following patch : It should use 2K frags instead of 4K
      for normal 1500 mtu
      
      Thanks !
      
      [PATCH] atl1c: use custom skb allocator
      
      We had reports ( https://bugzilla.kernel.org/show_bug.cgi?id=54021 )
      that using high order pages for skb allocations is problematic for atl1c
      
      We do not know exactly what the problem is, but we suspect that crossing
      4K pages is not well supported by this hardware.
      
      Use a custom allocator, using page allocator and 2K fragments for
      optimal stack behavior. We might make this allocator generic
      in future kernels.
