scripts/kernel-doc: handle object-like macros

2014-07-12T18:30:36Z

Object-like macros are different than function-like macros: https://gcc.gnu.org/onlinedocs/cpp/Object-like-Macros.html https://gcc.gnu.org/onlinedocs/cpp/Function-like-Macros.html They are not parsed correctly, generating invalid intermediate files (xmls) for cases like: #define BIT_MASK (0xFF << BIT_SHIFT) where "OxFF <<" is considered to be parameter type. When parsing, we can differentiate beween these two types of macros by checking whether there is at least one whitespace b/w "#define" and first opening parenthesis.

Pull MIPS fixes from Ralf Baechle: "This is dominated by a large number of changes necessary for the MIPS BPF code. code. Aside of that there are - a fix for the MSC system controller support code. - a Turbochannel fix. - a recordmcount fix that's MIPS-specific. - barrier fixes to smp-cps / pm-cps after unrelated changes elsewhere in the kernel. - revert support for MSA registers in the signal frames. The reverted patch did modify the signal stack frame which of course is inacceptable. - fix math-emu build breakage with older compilers. - some related cleanup. - fix Lasat build error if CONFIG_CRC32 isn't set to y by the user" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (27 commits) MIPS: Lasat: Fix build error if CRC32 is not enabled.

recordmcount/MIPS: Fix possible incorrect mcount_loc table entries in modules

2014-06-26T09:48:19Z

On MIPS calls to _mcount in modules generate 2 instructions to load the _mcount address (and therefore 2 relocations). The mcount_loc table should only reference the first of these, so the second is filtered out by checking the relocation offset and ignoring ones that immediately follow the previous one seen. However if a module has an _mcount call at offset 0, the second relocation would not be filtered out due to old_r_offset == 0 being taken to mean that the current relocation is the first one seen, and both would end up in the mcount_loc table. This results in ftrace_make_nop() patching both (adjacent) instructions to branches over the _mcount call sequence like so: 0xffffffffc08a8000: 04 00 00 10 b 0xffffffffc08a8014 0xffffffffc08a8004: 04 00 00 10 b 0xffffffffc08a8018 0xffffffffc08a8008: 2d 08 e0 03 move at,ra ... The second branch is in the delay slot of the first, which is defined to be unpredictable - on the platform on which this bug was encountered, it triggers a reserved instruction exception. Fix by initializing old_r_offset to ~0 and using that instead of 0 to determine whether the current relocation is the first seen.

builddeb: fix missing headers in linux-headers package

2014-06-18T19:36:36Z

The kernel headers package (linux-headers) doesn't include several header files required to build out-of-tree modules. It makes the package unusable on e.g. ARM architecture: /usr/src/linux-headers-3.14.0/arch/arm/include/asm/memory.h:24:25: fatal error: mach/memory.h: No such file or directory #include ^ compilation terminated.

kbuild: Fix tar-pkg with relative $(objtree)

2014-06-18T15:34:59Z

Commit 7e1c0477 (kbuild: Use relative path for $(objtree)) assumes that the build process does not change its working directory. make tar-pkg was a couterexample, fix this by changing directory only for the tar command and not for the whole script, which at one point references the now relative $(objtree).

deb-pkg: Fix for relative paths

2014-06-18T14:01:58Z

When $srctree or $objtree are relative paths, we cannot change directory and refer to them in the same subshell. Do the redirection outside of the subshell to fix this. Reported-and-tested-by: Ilya Dryomov Signed-off-by: Michal Marek
