David Vrabel 82639998a5 Fix emacs local variable block to use correct C style variable.
The emacs variable to set the C style from a local variable block is
c-file-style, not c-set-style.

Shriram Rajagopalan f6b3d39f5d tools/libxc: Remus Checkpoint Compression
Instead of sending dirty pages of guest memory as-is, use a simple compression
algorithm that sends a RLE-encoded XOR of the page against its last sent copy.
A small LRU cache is used to hold recently dirtied pages. Pagetable pages are
sent as-is, as they are canonicalized at sender side and uncanonicalized at
receiver.

[ Fixed up a conflict in sg_save_restore.h.  I had to increase the
  ID values used from -11 and -12 to -12 and -13 because -11 had
  been taken by ..._HVM_VIRIDIAN in the meantime. -iwj ]
