      kbuild: Fix genksyms handling of DEFINE_PER_CPU(struct foo_s *, bar); · a89a0a23
      Robin Holt authored 
      This is a one-line change to parse.y.
To take advantage of this the scripts/genksyms/*_shipped files needs to
be rebuild - this is the next patch.

When a .c file contains:
DEFINE_PER_CPU(struct foo_s *, bar);

the .cpp output looks like:
__attribute__((__section__(".data.percpu"))) __typeof__(struct foo_s *) per_cpu__bar;

With the existing parse.y, the value inside the paranthesis of
__typeof__() does not evaluate as a type_specifier and therefore
per_cpu__bar does not get assigned a type for genksyms which results in
the EXPORT_PER_CPU_SYMBOL() not generating a CRC value.

I have compared the Modules.symvers with and without this
patch and for ia64's defconfig, the only change is:
Before 0x00000000    per_cpu____sn_nodepda   vmlinux
After  0x9d3f3faa    per_cpu____sn_nodepda   vmlinux

per_cpu____sn_nodepda was the original source of my problems.

      kbuild: set correct KBUILD_MODNAME when using well known kernel symbols as module names · f83b5e32
      Ustyugov Roman authored 
      This patch fixes a problem when we use well known kernel symbols as module
names.

For example, if module source name is current.c, idle_stack.c or etc.,
we have a bad KBUILD_MODNAME value.
For example, KBUILD_MODNAME will be "get_current()" instead of "current", or
"(init_thread_union.stack)" instead of "idle_task".

The trick is to define a stringify macro on the commandline - named
KBUILD_STR for namespace reasons - and then to stringify the module
name.

There are a few uses of KBUILD_MODNAME throughout the tree but the usage
is for debug and will not be harmed by this change so left untouched for now.

While at it KBUILD_BASENAME was changed too. Any spinlock usage in the
unix module would have created wrong section names without it.
Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME.

Original patch from Ustyogov Roman - all bugs introduced by me.

      kbuild: escape '#' in .target.cmd files · 4d99f93b
      Sam Ravnborg authored 
      Commandlines are contained in the .<target>.cmd files and in case they
contain a '#' char make see this as start of comment.
Teach fixdep to escape the '#' char so make will assing the full commandline.

      kbuild: Add ctags support for function prototypes and external variable declarations · f6333eb4
      John Kacur authored 
      This patch adds function prototypes and external variable declarations
to the set of tag kinds when running ctags. I find this useful when
perusing the kernel. Please apply.

      kbuild: Fix crc-error warning on modules · 9572b28f
      Luke Yang authored 
         This is the patch for the following issue:

 In include/linux/module.h, "__crc_" and "__ksymtab_" are hard
coded to be the   prefix for some kinds of symbols (CRC symbol and
ksymtab section). But in script /mod/modpost.c,
MODULE_SYMBOL_PREFIX##"__crc_" is used as the prefix to search CRC
symbols. So if an architecture (such as h8300 or Blackfin) defines
MODULE_SYMBOL_PREFIX as not NULL ("_"), modpost will always warn about
"no invalid crc".
  And it is the same with KSYMTAB_PFX.
