Changes since v1:
  * Peter fixes the elfload bug that prevented ARM using the proper
    MAX_RESERVED_VA setting.
  * Adjust the arm MAX_RESERVED_VA.

Peter Maydell (1):
  linux-user: Allow -R values up to 0xffff0000 for 32-bit ARM guests

Richard Henderson (3):
  tcg: Fix off-by-one in assert in page_set_flags
  linux-user: Tidy and enforce reserved_va initialization
  linux-user/sh4: Reduce TARGET_VIRT_ADDR_SPACE_BITS to 31
