      kbuild: fix false section mismatch warnings · 5ecdd0f6
      由 Sam Ravnborg 提交于 
      Darren Jenkins <darrenrjenkins@gmail.com> pointed out a
number of false positives where we referenced variables
from a _driver variable.
Fix it by check for that pattern and ignore it.

Randy.Dunlap <rdunlap@xenotime.net> pointed out a similar
set of warnings for a number of scsi drivers.
In scsi world they misname their variables *_template or
*_sht so add these to list of variables that may have references
to .init.text with no warning.

Randy.Dunlap <rdunlap@xenotime.net> also pointed out a scsi driver
with many references to .exit.text from .rodata. This is compiler
generated references and we already ignore these for .init.text, so
ignore them for .exit.text also.

      [PATCH] kbuild: fix buffer overflow in modpost · 7670f023
      由 Sam Ravnborg 提交于 
      Jiri Benc <jbenc@suse.cz> reported that modpost would stop with SIGABRT if
used with long filepaths.
The error looked like:
>   Building modules, stage 2.
>   MODPOST
> *** glibc detected *** scripts/mod/modpost: realloc(): invalid next size:
+0x0809f588 ***
> [...]

Fix this by allocating at least the required memory + SZ bytes each time.
Before we sometimes ended up allocating too little memory resuting in the
glibc detected bug above.  Based on patch originally submitted by: Jiri

      kbuild: do not warn when unwind sections references .init/.exit sections · 6e10133f
      由 Sam Ravnborg 提交于 
      Andrew Morton reported a number of false positives for ia64 - like these:
WARNING: drivers/acpi/button.o - Section mismatch: reference to .init.text: from .IA_64.unwind.init.text after '' (at offset 0x0)
WARNING: drivers/acpi/button.o - Section mismatch: reference to .exit.text: from .IA_64.unwind.exit.text after '' (at offset 0x0)
WARNING: drivers/acpi/processor.o - Section mismatch: reference to .init.text: from .IA_64.unwind after '' (at offset 0x1e8)

They are all false positives - or at least the .c code looks OK.
It is not known why sometimes a section name is appended and sometimes not.

Fix is to accept references from all sections that includes "unwind." in the name.

      kbuild: check for section mismatch during modpost stage · b39927cf
      由 Sam Ravnborg 提交于 
      Section mismatch is identified as references to .init*
sections from non .init sections. And likewise references
to .exit.* sections outside .exit sections.

.init.* sections are discarded after a module is initialized
and references to .init.* sections are oops candidates.
.exit.* sections are discarded when a module is built-in and
thus references to .exit are also oops candidates.

The checks were possible to do using 'make buildcheck' which
called the two perl scripts: reference_discarded.pl and
reference_init.pl. This patch just moves the same functionality
inside modpost and the scripts are then obsoleted.
They will though be kept for a while so users can do double
checks - but note that some .o files are skipped by the perl scripts
so result is not 1:1.
All credit for the concept goes to Keith Owens who implemented
the original perl scrips - this patch just moves it to modpost.

Compared to the perl script the implmentation in modpost will be run
for each kernel build - thus catching the error much sooner, but
the downside is that the individual .o file are not always identified.

      kbuild: improved modversioning support for external modules · 040fcc81
      由 Sam Ravnborg 提交于 
      With following patch a second option is enabled to obtain
symbol information from a second external module when a
external module is build.
The recommended approach is to use a common kbuild file but
that may be impractical in certain cases.
With this patch one can copy over a Module.symvers from one
external module to make symbols (and symbol versions) available
for another external module.

      kbuild: set correct KBUILD_MODNAME when using well known kernel symbols as module names · f83b5e32
      由 Ustyugov Roman 提交于 
      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: Fix crc-error warning on modules · 9572b28f
      由 Luke Yang 提交于 
         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.
