      This patch updates the _shipped files for genksyms.
See previous patch for actual functional changes.

      kbuild: __extension__ support in genksyms (fix unknown CRC warning) · 3550a516
      由 Sam Ravnborg 提交于 
      Recently the __extension__ keyword has been introduced in the kernel.
Teach genksyms about this keyword so it can generate correct CRC for
exported symbols that uses a symbol marked __extension__.
For now only the typedef variant:

	__extension__ typedef ...

is supported.
Later we may add more variants as needed.

This patch contains the actual source file changes. The
following patch will hold modifications to the generated
files (*_shipped) and only after the second patch the fix
has effect.

      kbuild: fix genksyms Makefile · a3a6261a
      由 Sam Ravnborg 提交于 
      When enabling GENERATE_PARSER the genksyms Makefile
failed to create _shipped version of generated files.

Modifying keywords.gperf failed to cause a rebuild
of genksyms.
Fixed by specifying keywowrds .c as explicit prerequisite
of the lexer.

      kbuild: replace abort() with exit(1) · 6803dc0e
      由 Sam Ravnborg 提交于 
      We have had no use of the coredump file for a long time.
So just exit(1) and avoid coredumping.

      kbuild: support for %.symtypes files · 15fde675
      由 Andreas Gruenbacher 提交于 
      Here is a patch that adds a new -T option to genksyms for generating dumps of
the type definition that makes up the symbol version hashes. This allows to
trace modversion changes back to what caused them. The dump format is the
name of the type defined, followed by its definition (which is almost C):

  s#list_head struct list_head { s#list_head * next , * prev ; }

The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef.
The exported symbols do not define types, and thus do not have an x# prefix:

  nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 )

The symbol type defintion of a single file can be generated with:

  make fs/jbd/journal.symtypes

If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that
export symbols are generated.

The single *.symtypes files can be combined into a single file after a kernel
build with a script like the following:

for f in $(find -name '*.symtypes' | sort); do
    f=${f#./}
    echo "/* ${f%.symtypes}.o */"
    cat $f
    echo
done \
| sed -e '\:UNKNOWN:d' \
      -e 's:[,;] }:}:g' \
      -e 's:\([[({]\) :\1:g' \
      -e 's: \([])},;]\):\1:g' \
      -e 's: $::' \
      $f \
| awk '
/^.#/   { if (defined[$1] == $0) {
            print $1
            next
          }
          defined[$1] = $0
        }
        { print }
'

When the kernel ABI changes, diffing individual *.symtype files, or the
combined files, against each other will show which symbol changes caused the
ABI changes. This can save a tremendous amount of time.

      kbuild: Fix genksyms handling of DEFINE_PER_CPU(struct foo_s *, bar); · a89a0a23
      由 Robin Holt 提交于 
      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.

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
