#   The TI_VFPSTATE is otherwise undefined and gas-2.15.90 (and probably

#   [ARM PATCH] 2395/1: __ioremap() miscalculates mapping size under certain conditions
#   
#   Patch from Lothar Wassmann
#   
#   Hi,
#   ioremapping a memory range that ends on the first byte of a page
#   (e.g. mapping PAGE_SIZE + 1 bytes on a page boundary) results in a
#   mapping that is one page too short. In particular trying to create a 1
#   byte mapping at the start of a page results in a BUG_ON() assertion in
#   remap_area_pages() because the calculated mapping size is zero.
#   This bug has been reported on Bugzilla on 2004-02-25:
#   http://bugzilla.kernel.org/show_bug.cgi?id=2188
