This adds some helper routines for uncached mapping support. This simplifies some of the cases where we need to check the uncached mapping boundaries in addition to giving us a centralized location for building more complex manipulation on top of. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

# Special flags for fault_64.o. This puts restrictions on the number of
|
|
# caller-save registers that the compiler can target when building this file.
|
|
# This is required because the code is called from a context in entry.S where
|
|
# very few registers have been saved in the exception handler (for speed
|
|
# reasons).
|
|
# The caller save registers that have been saved and which can be used are
|
|
# r2,r3,r4,r5 : argument passing
|
|
# r15, r18 : SP and LINK
|
|
# tr0-4 : allow all caller-save TR's. The compiler seems to be able to make
|
|
# use of them, so it's probably beneficial to performance to save them
|
|
# and have them available for it.
|
|
#
|
|
# The resources not listed below are callee save, i.e. the compiler is free to
|
|
# use any of them and will spill them to the stack itself.
