linux-next: manual merge of the omap tree with the arm tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Today's linux-next merge of the omap tree got a conflict in
arch/arm/mach-omap1/include/mach/debug-macro.S
arch/arm/mach-omap2/include/mach/debug-macro.S between commit
7f62dc4756eaf761570b96250630d48f80397d64 ("ARM: 5910/1: ARM: Add tmp
register for addruart and loadsp") from the arm tree and commit 209f5d2d2c8e385834d138ac593df86504a28ffe ("omap: Make
uncompress code and DEBUG_LL code generic") from the omap tree.

I fixed it up (see below) and can carry the fix as necessary.
