      tracing: Only print objcopy version warning once from recordmcount · 638adb05
      Steven Rostedt authored
      If the user has an older version of objcopy, that can not handle
      converting local symbols to global and vice versa, then some
      functions will not be part of the dynamic function tracer. The current
      code in recordmcount.pl will print a warning in this case. Unfortunately,
      there exists lots of files that may have this issue with older objcopys
      and this will cause a warning for every file compiled with this
      issue.
      
      This patch solves this overwhelming output by creating a
      .tmp_quiet_recordmcount file on the first instance the warning is
      encountered. The warning will not print if this file exists.
      
      The temp file is deleted at the beginning of the compile to ensure that
      the warning will happen once again on new compiles (because the issue
      is still present).

      kbuild: revert "save ARCH & CROSS_COMPILE ..." · 2331d1a6
      Sam Ravnborg authored
      Revert commit 57554334
      
      It caused following issues:
      
      - On architectures where ARCH= setting is used to select between
        32 and 64 bit this was no longer possible without "make mrproper"
      - If ARCH was changed then kbuild refused to run "make mrproper"
        because ARCH had changed
      - When CROSS_COMPILE was changed people were asked to run "make mrproper"
        but kbuild refused to run "make mrproper" because CROSS_COMPILE changed.
      - Spaces in CROSS_COMPILE was not 'supported'
      - If an non-existing ARCH= was used kbuild could get stuck
      
      Lessons learned:
      . Despite being simple and straghtforward people uses very different
        approaches when building the kernel.
      
      . CROSS_COMPILE is sometimes used for ccache despite cache being
        only a CC frontend so one would have expected CC to be
        used for this purpose.
      
      . And obviously this was not tested widely enough.

      I'm skipping -rc2 because the -rc1 Makefile mistakenly said -rc2, so in
      order to avoid confusion, I'm jumping from -rc1 to -rc3.  That way, when
      'uname' (or an oops report) says 2.6.32-rc2, there's no confusion about
      whether people perhaps meant -rc1 or -rc2.

      arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0 · 51b563fc
      Sam Ravnborg authored
      Albin Tonnerre <albin.tonnerre@free-electrons.com> reported:
      
          Bash 4 filters out variables which contain a dot in them.
          This happends to be the case of CPPFLAGS_vmlinux.lds.
          This is rather unfortunate, as it now causes
          build failures when using SHELL=/bin/bash to compile,
          or when bash happens to be used by make (eg when it's /bin/sh)
      
      Remove the common definition of CPPFLAGS_vmlinux.lds by
      pushing relevant stuff to either Makefile.build or the
      arch specific kernel/Makefile where we build the linker script.
      
      This is also nice cleanup as we move the information out where
      it is used.
      
      Notes for the different architectures touched:
      
      arm - we use an already exported symbol
      cris - we use a config symbol aleady available
             [Not build tested]
      mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
             Added a few variables to CPPFLAGS - they are only used by
             the linker script.
             [Not build tested]
      powerpc - removed assignment that is not needed
                [not build tested]
      sparc - simplified it using $(BITS)
      um - introduced a few new exported variables to deal with this
      xtensa - added options to CPP invocation
               [not build tested]

      The upcomming gcc 4.5 has a new -fconserve-stack option that tells the
      inliner to take stack frame size in account.  Set it if the compiler

      Andi Kleen authored
      The new alternative `gold' linker in recent binutils doesn't support
      the -X option. This breaks allyesconfig builds that have
      CONFIG_STRIP_ASM_SYMS enabled. Check if the linker really supports
      the option using ld-option.

      kbuild: save ARCH & CROSS_COMPILE when building a kernel · 57554334
      Sam Ravnborg authored
      When building a kernel for a different architecture
      kbuild requires the user always to specify ARCH and
      CROSS_COMPILE on the command-line.
      
      We use the asm symlink to detect if user forgets to
      specify the correct ARCH value - but that symlink
      is about to die. And we do now want to loose this check.
      
      This patch save the settings of ARCH and CROSS_COMPILE
      in two files named:
      
          include/generated/kernel.arch
          include/generated/kernel.cross
      
      The settings are saved during "make *config" time
      and always read.
      
      If user try to change the settings we error out.
      
      This works both for plain builds and for O=...
      builds.
      
      So now you can do:
      $ mkdir sparc64
      $ make O=sparc64 ARCH=sparc64 CROSS_COMPILE=sparc64-linux- defconfig
      $ cd sparc64
      $ make
      
      Notice that you no longer need to tell kbuild
      the settings of ARCH and CROSS_COMPILE when you type make
      in the output directory.
      
      Likewise for plain builds where you do not use O=...

      kbuild: use INSTALLKERNEL to select customized installkernel script · caa27b66
      Sam Ravnborg authored
      Replace the use of CROSS_COMPILE to select a customized
      installkernel script with the possibility to set INSTALLKERNEL
      to select a custom installkernel script when running make:
      
          make INSTALLKERNEL=arm-installkernel install
      
      With this patch we are now more consistent across
      different architectures - they did not all support use
      of CROSS_COMPILE.
      
      The use of CROSS_COMPILE was a hack as this really belongs
      to gcc/binutils and the installkernel script does not change
      just because we change toolchain.
      
      The use of CROSS_COMPILE caused troubles with an upcoming patch
      that saves CROSS_COMPILE when a kernel is built - it would no
      longer be installable.
      [Thanks to Peter Z. for this hint]
      
      This patch undos what Ian did in commit:
      
        0f8e2d62
        ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")
      
      The patch has been lightly tested on x86 only - but all changes
      looks obvious.
