      kconfig: add symbol value to help find the real depend · 544e433a
      Cheng Renquan authored
      Sometimes when configuring need to disable some unused item, but the item is
      selected by many other items, it's hard to find the real dependency which
      selected it, This patch add every symbol's value accompanied to make it
      possible to find the real dependency easily.
      
      An example is CONFIG_RFKILL,

      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.
