  • a1f42beb8   Makefile: fix up CROSS_COMPILE and READABLE_ASM interaction. ... Browse Code »

    When the READABLE_ASM cc-option tests were added they were done so prior
    to the arch Makefile include, resulting in cc-option being run on the
    host cc instead of the factoring in the cross prefix set up by the
    architecture.

    This bumps the include back up so that cc-option actually runs on the
    compiler that we're building with.

  • 269af9a1a   Merge branch 'x86-extable-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip ... Browse Code »

    Pull exception table generation updates from Ingo Molnar:
    "The biggest change here is to allow the build-time sorting of the
    exception table, to speed up booting. This is achieved by the
    architecture enabling BUILDTIME_EXTABLE_SORT. This option is enabled
    for x86 and MIPS currently.

    On x86 a number of fixes and changes were needed to allow build-time
    sorting of the exception table, in particular a relocation invariant
    exception table format was needed. This required the abstracting out
    of exception table protocol and the removal of 20 years of accumulated
    assumptions about the x86 exception table format.

    While at it, this tree also cleans up various other aspects of
    exception handling, such as early(er) exception handling for
    rdmsr_safe() et al.

    All in one, as the result of these changes the x86 exception code is
    now pretty nice and modern. As an added bonus any regressions in this
    code will be early and violent crashes, so if you see any of those,
    you'll know whom to blame!"

    Fix up trivial conflicts in arch/{mips,x86}/Kconfig files due to nearby
    modifications of other core architecture options.

    - kernel support for AMD IBS PMU hardware features. Notably 'perf

    skid now, like PEBS does on the Intel side, because it takes
    advantage of IBS transparently.

    - the libtracevents library: it is the first step towards unifying
    tracing tooling and perf, and it also gives a tracing library for
    external tools like powertop to rely on.

    - infrastructure: various improvements and refactoring of the UI
    modules and related code

    - infrastructure: cleanup and simplification of the profiling
    targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.)

    - tons of robustness fixes all around

    - various ftrace updates: speedups, cleanups, robustness
    improvements.

    - typing 'make' in tools/ will now give you a menu of projects to

  • 6520fe556   x86, realmode: 16-bit real-mode code support for relocs tool ... Browse Code »
    129

    A new option is added to the relocs tool called '--realmode'.
    This option causes the generation of 16-bit segment relocations
    and 32-bit linear relocations for the real-mode code. When
    the real-mode code is moved to the low-memory during kernel
    initialization, these relocation entries can be used to
    relocate the code properly.

    In the assembly code 16-bit segment relocations must be relative
    to the 'real_mode_seg' absolute symbol. Linear relocations must be
    relative to a symbol prefixed with 'pa_'.

    16-bit segment relocation is used to load cs:ip in 16-bit code.
    Linear relocations are used in the 32-bit code for relocatable
    data references. They are declared in the linker script of the
    real-mode code.

    The relocs tool is moved to arch/x86/tools/relocs.c, and added new
    target archscripts that can be used to build scripts needed building
    an architecture. be compiled before building the arch/x86 tree.

    [ hpa: accelerating this because it detects invalid absolute
    relocations, a serious bug in binutils 2.22.52.0.x which currently
    produces bad kernels. ]

  • 1f2bfbd00   kbuild: link of vmlinux moved to a script ... Browse Code »
    86

    Move the final link of vmlinux to a script to improve
    readability and maintainability of the code.

    The Makefile fragments used to link vmlinux has over the
    years seen far too many changes and the logic had become
    hard to follow.

    As the process by nature is serialized there was
    nothing gained including this in the Makefile.

    "um" has special link requirments - and the
    only way to handle this was to hard-code the linking
    of "um" in the script.
    This was better than trying to modularize it only for the
    benefit of "um" anyway.

    The shell script has been improved after input from:

    sparc32 has hardcoded knowledge of kallsyms support. This fix
    include support for EXTRA_KALLSYM_PASS=1.
    The ugly part is that it is hardcoded in the arch/sparc/boot

    If you want to build and install it, do

    $ make tools/_clean

    If you want to clean all in tools, simply do
