scripts/recordmcount.pl: There is no -m32 gcc option on Super-H anymore

2015-01-30T01:40:43Z

commit 1caf6aaaa47471831d77c75f094d4e00ad1ec808 upstream. Compiling SH with gcc-4.8 fails due to the -m32 option not being supported.

s390/ftrace: remove 31 bit ftrace support

2014-10-09T07:14:18Z

31 bit and 64 bit diverge more and more and it is rather painful to keep both parts running. To make things simpler just remove the 31 bit support which nobody uses anyway. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

ftrace: Add arm64 support to recordmcount

2014-05-29T08:04:31Z

Recordmcount utility under scripts is run, after compiling each object, to find out all the locations of calling _mcount() and put them into specific seciton named __mcount_loc. Then linker collects all such information into a table in the kernel image (between __start_mcount_loc and __stop_mcount_loc) for later use by ftrace. This patch adds arm64 specific definitions to identify such locations. There are two types of implementation, C and Perl. On arm64, only C version is used to build the kernel now that CONFIG_HAVE_C_RECORDMCOUNT is on. But Perl version is also maintained. This patch also contains a workaround just in case where a header file, elf.h, on host machine doesn't have definitions of EM_AARCH64 nor R_AARCH64_ABS64. Without them, compiling C version of recordmcount will fail. Acked-by: Will Deacon Signed-off-by: AKASHI Takahiro Signed-off-by: Will Deacon

ftrace: default to tilegx if ARCH=tile is specified

recordmcount.pl: Add support for fentry

2013-11-05T21:07:50Z

With gcc 4.6.0 the -mfentry feature places the function profiling call at the start of the function. When this is used, the call is to __fentry__ and not mcount. This is required for Ksplice as the C version of recordmcount doesn't insert section symbols for the __mcount_loc section so we fall back to the perl version. Based on 48bb5dc6cd9d30fe0d594947563da1f8bd9abada (ftrace: Make recordmcount.c handle __fentry__).

ftrace: Add .kprobe.text section to whitelist for recordmcount.c

2011-05-16T18:42:15Z

The .kprobe.text section is safe to modify mcount to nop and tracing. Add it to the whitelist in recordmcount.c and recordmcount.pl. Cc: John Reiser Cc: Masami Hiramatsu Link: http://lkml.kernel.org/r/20110421023737.743350547@goodmis.org Signed-off-by: Steven Rostedt

ftrace: Add .ref.text as one of the safe areas to trace

2011-03-10T15:34:39Z

The section .ref.text will not go away unexpectedly and is safe to trace. Add it to the safe list of sections to allow tracing. Signed-off-by: Steven Rostedt
