      kbuild: introduce ccflags-y, asflags-y and ldflags-y · f77bf014
      由 Sam Ravnborg 提交于 
      Introduce ccflags-y, asflags-y and ldflags-y so we soon can
deprecate use of EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS.
This patch does not touch any in-tree users - thats next round.
Lets get this committed first and then fix the users of the
soon to be deprecated variants next.

The rationale behind this change is to introduce support for
makefile fragments like:

ccflags-$(CONFIG_WHATEVER_DEBUG) := -DDEBUG

As a replacement for the uglier:
ifeq ($(CONFIG_WHATEVER_DEBUG),y)
        EXTRA_CFLAGS := -DDEBUG
endif

      kbuild: enable 'make CPPFLAGS=...' to add additional options to CPP · 06c5040c
      由 Sam Ravnborg 提交于 
      The variable CPPFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.

This patch replace use of CPPFLAGS with KBUILD_CPPFLAGS all over the
tree and enabling one to use:
make CPPFLAGS=...
to specify additional CPP commandline options.

Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390

      kbuild: check for wrong use of CFLAGS · 0c53c8e6
      由 Sam Ravnborg 提交于 
      External modules have in a few cases modifed gcc option
by modifying CFLAGS. This has never been documented and
was a bad practice.
With the check to use KBUILD_CFLAGS it will no longer work
so we better error out and tell what was wrong as a service
to the external module users.

This check can be overruled if
KBUILD_NOPEDANTIC is set to something.
Addid this possibility may allow older external
module to build without any code modifications but potentially
only loosing some un-important gcc options.

      kbuild: enable 'make CFLAGS=...' to add additional options to CC · a0f97e06
      由 Sam Ravnborg 提交于 
      The variable CFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.
On top of that several people over time has asked for a way to
pass in additional flags to gcc.

This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
tree and enabling one to use:
make CFLAGS=...
to specify additional gcc commandline options.

One usecase is when trying to find gcc bugs but other
use cases has been requested too.

Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k

Test was simple to do a defconfig build, apply the patch and check
that nothing got rebuild.

      update checkpatch.pl to version 0.09 · 22f2a2ef
      由 Andy Whitcroft 提交于 
      This version brings a number of new checks, and a number of bug
fixes.  Of note:

  - checks for spacing on round and square bracket combinations
  - loosening of the single statement brace checks, to allow
    them when they contain comments or where other blocks in a
    compound statement have them.
  - parks the multple declaration support
  - allows architecture defines in architecture specific headers

Andy Whitcroft (21):
      Version: 0.09
      loosen single statement brace checks
      fix up multiple declaration to avoid function arguments
      add some function space parenthesis check exceptions
      handle EXPORT_'s with parentheses in their names
      clean up some warnings in multi-line macro bracketing support
      park the multiple declaration checks
      make block brace checks count comments as a statement
      __volatile__ and __extension__ are not functions
      allow architecture specific defined within architecture includes
      check spacing on square brackets
      check spacing on parentheses
      ensure we apply checks to the part before start comment
      check #ifdef conditional spacing
      handle __init_refok and __must_check
      add noinline to inline checks
      prevent email addresses from tripping spacing checks
      handle typed initialiser spacing
      handle line contination as end of line
      add bool to the type matcher
      refine EXPORT_SYMBOL checks to handle pointers

      kbuild: fix modpost warnings for xtensa · cb7e51d8
      由 Sam Ravnborg 提交于 
      The Xtensa architecture places literal pools in sections separate
from the instructions. The corresponsing text sections, therefore,
reference the .literal section, and we have to suppress those
warnings.

The naming convention defines the name for a literal
section as .SECTION.literal, unless .SECTION is .text. In that case
the name is only .literal. Using strncmp() instead of strcmp()
to compare the from-section with .SECTION.init.refok in pattern 0
should not cause any regressions for other architectures.

We also need to suppress warnings for two informational
sections (.xt.lit and .xt.prop) used by the Xtensa architecture.

      kbuild: be more foregiving on init section naming · 83cda2bb
      由 Sam Ravnborg 提交于 
      In the whitelist function of modpost now use the same
check to identify init_section as in other places of modpost.
This has the effect that we now recognize sections named
.init.text.19 as init sections and we no longer warn
when we see these.

At the same time make surrounding code readable by dropping
use of temporary flags.
