      kbuild: check asm symlink when building a kernel · fc333b2d
      Sam Ravnborg authored
      We often hit the situation where the asm symlink
      in include/ points to the wrong architecture.
      In 9 out of 10 cases thats because we forgot to set
      ARCH but sometimes we just reused the same tree
      for another ARCH. For the merged x86 tree we need
      to create a new symlink but this is not obvious.
      So with the following patch we check if the symlink
      points to the correct architecture and error
      out if this is not the case.

      kbuild: enable 'make CFLAGS=...' to add additional options to CC · a0f97e06
      Sam Ravnborg authored
      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.

      kbuild: call make once for all targets when O=.. is used · 0b35786d
      Milton Miller authored
      Change the invocations of make in the output directory Makefile and the
      main Makefile for separate object trees to pass all goals to one $(MAKE)
      via a new phony target "sub-make" and the existing target _all.
      
      When compiling with separate object directories, a separate make is called
      in the context of another directory (from the output directory the main
      Makefile is called, the Makefile is then restarted with current directory
      set to the object tree).  Before this patch, when multiple make command
      goals are specified, each target results in a separate make invocation.
      With make -j, these invocations may run in parallel, resulting in multiple
      commands running in the same directory clobbering each others results.
      
      I did not try to address make -j for mixed dot-config and no-dot-config
      targets.  Because the order does matter, a solution was not obvious.
      Perhaps a simple check for MAKEFLAGS having -j and refusing to run would
      be appropriate.

      kbuild: pass -g to assembler under CONFIG_DEBUG_INFO · cf851aa7
      Roland McGrath authored
      The assembler for a while now supports -gdwarf to generate source line info
      just like the C compiler does.  Source-level assembly debugging sounds like an
      oxymoron, but it is handy to be able to see the right source file and read its
      comments rather than just the disassembly.  This patch enables -gdwarf for
      assembly files when CONFIG_DEBUG_INFO=y and the assembler supports the option.

      kbuild: fix infinite make recursion · 4f1127e2
      Sam Ravnborg authored
      Jan Engelhardt <jengelh@computergmbh.de> reported:
      You can cause a recursion in kbuild/make with the following:
      
      make O=$PWD kernel/time.o
      make mrproper
      
      Of course no one would use O=$PWD (that's just the testcase),
      but this happened too often:
      
      /ws/linux/linux-2.6.23$ make O=/ws/linux/linux-2.6.23 kernel/time.o
      (Oops - should have been O=/ws/linux/obj-2.6.23!)
      
      Fixed by an explicit test for this case - we error
      out if output directory and source directory are the same.

      kbuild: clean Modules.symvers in external module dirs · c34114f4
      Mike Frysinger authored
      At the moment, running `make clean` in an external module directory does a
      nice job of cleaning up with one exception: it leaves behind Modules.symvers.
      Attached patch adds this file to the clean list for external modules.

      Use --build-id ld option · 18991197
      Roland McGrath authored
      This change passes the --build-id when linking the kernel and when linking
      modules, if ld supports it.  This is a new GNU ld option that synthesizes an
      ELF note section inside the read-only data.  The note in this section contains
      unique identifying bits called the "build ID", which are generated so as to be
      different for any two linked ELF files that aren't identical.  The build ID
      can be recovered from stripped files, memory dumps, etc.  and used to look up
      the original program built, locate debuginfo or other details or history
      associated with it.  For normal program linking, the compiler passes
      --build-id to ld by default, but the option is needed when using ld directly
      as we do.
