To: linux-arm-kernel
This patchset moves the MSM code over to DEBUG_LL_INCLUDE
as well as removes the rest of the static mappings made on
8x60 and 8960. This allows us to remove the msm_iomap-8x60.h
msm_iomap-8960.h. Note that debug_ll_io_init() will
be the default in 3.11 so we'll have to make a sweep in the merge
window or after to remove those two.
Patches are based on David Brown's MSM for-next tree.

ARM: msm: Move debug-macro.S to include/debug
ARM: msm: Remove TMR and TMR0 static mappings
ARM: msm: Don't compile __msm_ioremap_caller() unless used

Hmm debug_ll_io_init() uses MT_DEVICE so I think I'll add a dummy
entry here and fill in the address with debug_ll_addr.

* [PATCH 2/3] ARM: msm: Remove TMR and TMR0 static mappings

Nobody is using these mappings so just drop them. of_iomap() in
the timer driver will take care of it for us. Doing this allows
us to remove the 8x60 and 8960 iomap files completely.

Nobody is using these mappings so just drop them. of_iomap() in
the timer driver will take care of it for us. Doing this allows
us to remove the 8x60 and 8960 iomap files completely.

This function is only used on MSM7x00A so only compile the
function if the build includes support for that platform.
