recordmcount: Fix handling of elf64 big-endian objects.

2012-01-26T01:24:50+00:00

commit 2e885057b7f75035f0b85e02f737891482815a81 upstream. In ELF64, the sh_flags field is 64-bits wide. recordmcount was erroneously treating it as a 32-bit wide field. For little endian objects this works because the flags of interest (SHF_EXECINSTR) reside in the lower 32 bits of the word, and you get the same result with either a 32-bit or 64-bit read. Big endian objects on the other hand do not work at all with this error. The fix: Correctly treat sh_flags as 64-bits wide in elf64 objects. The symptom I observed was that my __start_mcount_loc..__stop_mcount_loc was empty even though ftrace function tracing was enabled.

kconfig/streamline-config.pl: Fix parsing Makefile with variables

2012-01-26T01:24:47+00:00

commit 364212fddaaa60c5a64f67a0f5624ad996ecc8a0 upstream. Thomas Lange reported that when he did a 'make localmodconfig', his config was missing the brcmsmac driver, even though he had the module loaded. Looking into this, I found the file: drivers/net/wireless/brcm80211/brcmsmac/Makefile had the following in the Makefile: MODULEPFX := brcmsmac obj-$(CONFIG_BRCMSMAC) += $(MODULEPFX).o The way streamline-config.pl works, is parsing all the obj-$(CONFIG_FOO) += foo.o lines to find that CONFIG_FOO belongs to the module foo.ko. But in this case, the brcmsmac.o was not used, but a variable in its place. By changing streamline-config.pl to remember defined variables in Makefiles and substituting them when they are used in the obj-X lines, allows Thomas (and others) to have their brcmsmac module stay configured when it is loaded and running "make localmodconfig".

kconfig/streamline-config.pl: Simplify backslash line concatination

commit d060d963e88f3e990cec2fe5214de49de9a49eca upstream. Simplify the way lines ending with backslashes (continuation) in Makefiles is parsed. This is needed to implement a necessary fix. Tested-by: Thomas Lange Signed-off-by: Steven Rostedt Signed-off-by: Greg Kroah-Hartman

kbuild: Fix help text not displayed in choice option.

2011-11-11T17:36:57+00:00

commit 3f198dfee49d2e9c30583c62b0c79286c78c7b44 upstream. Help text under choice menu is never displayed because it does not have symbol name associated with it, however many kconfigs have help text under choice, assuming that it will be displayed when user selects help. for example in Kconfig if we have: choice prompt "Choice" ---help--- HELP TEXT ... config A bool "A" config B bool "B" endchoice Without this patch "HELP TEXT" is not displayed when user selects help option when "Choice" is highlighted from menuconfig or xconfig or gconfig. This patch changes the logic in menu_get_ext_help to display help for cases which dont have symbol names like choice.
