      xen/grant-table: refactor error cleanup in grow_gnttab_list() · 46e3626a
      Chen Gang authored
      The cleanup loop in grow_gnttab_list() is safe from the underflow of
      the unsigned 'i' since nr_glist_frames is >= 1, but refactor it
      anyway.

      xen/setup: Remap Xen Identity Mapped RAM · 4fbb67e3
      Matt Rushton authored
      Instead of ballooning up and down dom0 memory this remaps the existing mfns
      that were replaced by the identity map. The reason for this is that the
      existing implementation ballooned memory up and and down which caused dom0
      to have discontiguous pages. In some cases this resulted in the use of bounce
      buffers which reduced network I/O performance significantly. This change will
      honor the existing order of the pages with the exception of some boundary
      conditions.
      
      To do this we need to update both the Linux p2m table and the Xen m2p table.
      Particular care must be taken when updating the p2m table since it's important
      to limit table memory consumption and reuse the existing leaf pages which get
      freed when an entire leaf page is set to the identity map. To implement this,
      mapping updates are grouped into blocks with table entries getting cached
      temporarily and then released.
      
      On my test system before:
      Total pages: 2105014
      Total contiguous: 1640635
      
      After:
      Total pages: 2105014
      Total contiguous: 2098904

      Pull ARM fixes from Russell King:
       "Fixes for ARM, the most notable being the fix from Nathan Lynch to fix
        the state of various registers during execve, to ensure that data
        can't be leaked between two executables.
      
        Fixes from Victor Kamensky for get_user() on big endian platforms,
        since the addition of 8-byte get_user() support broke these fairly
        badly.
      
        A fix from Sudeep Holla for affinity setting when hotplugging CPU 0.
      
        A fix from Stephen Boyd for a perf-induced sleep attempt while atomic.
      
        Lastly, a correctness fix for emulation of the SWP instruction on
        ARMv7+, and a fix for wrong carry handling when updating the
        translation table base address on LPAE platforms"
      
      * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
        ARM: 8149/1: perf: Don't sleep while atomic when enabling per-cpu interrupts
        ARM: 8148/1: flush TLS and thumbee register state during exec
        ARM: 8151/1: add missing exports for asm functions required by get_user macro
        ARM: 8137/1: fix get_user BE behavior for target variable with size of 8 bytes
        ARM: 8135/1: Fix in-correct barrier usage in SWP{B} emulation
        ARM: 8133/1: use irq_set_affinity with force=false when migrating irqs
        ARM: 8132/1: LPAE: drop wrong carry flag correction after adding TTBR1_OFFSET
