[PATCH 07/10] ftrace: pass KBUILD_CFLAGS to
On ARM, we have two ABIs, and the ABI used is controlled via a config option. Object files built with one ABI can't be merged with object files built with the other ABI. So, needs to use the same compiler flags as the kernel when generating the object file with the mcount locations. Ensure this ... 13 Mar 2010 02:08
[PATCH 03/10] ftrace: allow building without frame pointers
With current gcc, compiling with both -pg and -fomit-frame-pointer is not allowed. However, -pg can be used to build without actually specying -fno-omit-frame-pointer, upon which the defaut behaviour for the target will be used. On ARM, it is not possible to build a Thumb-2 kernel with -fno-omit-frame-pointer (... 13 Mar 2010 02:08

[PATCH 00/10] ARM: ftrace: cleanups, Thumb-2, and dynamic ftrace (v2)
v2: Fixes as per review comments. The only code changes are the #error in 0004 and the removal of the #ifdef in 0009. The rest are comments and commit message rewording/expansion. This series contains fixes and improvements to the ARM ftrace support. It adds Thumb-2 support and re-implements the dynamic ftrace... 13 Mar 2010 02:08
