      tracing: Rename FTRACE_SYSCALLS for tracepoints · 66700001
      Josh Stone authored
      The syscall enter/exit tracing is no longer specific to just ftrace, so
      they now have names that reflect their tie to tracepoints instead.

      x86: remove the Voyager 32-bit subarch · 965c7eca
      Ingo Molnar authored
      Impact: remove unused/broken code
      The Voyager subarch last built successfully on the v2.6.26 kernel
      and has been stale since then and does not build on the v2.6.27,
      v2.6.28 and v2.6.29-rc5 kernels.
      No actual users beyond the maintainer reported this breakage.
      Patches were sent and most of the fixes were accepted but the
      discussion around how to do a few remaining issues cleanly
      fizzled out with no resolution and the code remained broken.
      In the v2.6.30 x86 tree development cycle 32-bit subarch support
      has been reworked and removed - and the Voyager code, beyond the
      build problems already known, needs serious and significant
      changes and probably a rewrite to support it.
      CONFIG_X86_VOYAGER has been marked BROKEN then. The maintainer has
      been notified but no patches have been sent so far to fix it.
      While all other subarchs have been converted to the new scheme,
      voyager is still broken. We'd prefer to receive patches which
      clean up the current situation in a constructive way, but even in
      case of removal there is no obstacle to add that support back
      after the issues have been sorted out in a mutually acceptable
      So remove this inactive code for now.

      x86: additional defconfig updates · 5b7e41ff
      H. Peter Anvin authored
      Additional updates to the x86 defconfigs.  The goals are, as before:
      - Make them usable to testers, more so than distributors or end users,
        both of which are likely to have their own config already.
      - Keep 32 and 64 bits as similar as is practical.
      - Use a more generic CPU type (ppro and generic, respectively).
      - Bump number of CPUs to 64 (few if any NR_CPUS arrays left).
      - Enable PAT.
      - Enable OPTIMIZE_INLINE.
      - Enable microcode update support.
      - Build SMT scheduler support (in addition to MC).

      Subject: devmem, x86: fix rename of CONFIG_NONPROMISC_DEVMEM · d092633b
      Ingo Molnar authored

      Date: Sat, 19 Jul 2008 15:47:17 -0700
      CONFIG_NONPROMISC_DEVMEM was a rather confusing name - but renaming it
      to CONFIG_PROMISC_DEVMEM causes problems on architectures that do not
      support this feature; this patch renames it to CONFIG_STRICT_DEVMEM,
      so that architectures can opt-in into it.
      ( the polarity of the option is still the same as it was originally; it
        needs to be for now to not break architectures that don't have the
        infastructure yet to support this feature)

      x86: add optimized inlining · 60a3cdd0
      Ingo Molnar authored
      allow gcc to optimize the kernel image's size by uninlining
      functions that have been marked 'inline'. Previously gcc was
      forced by Linux to always-inline these functions via a gcc
       #define inline	inline __attribute__((always_inline))
      Especially when the user has already selected
      CONFIG_OPTIMIZE_FOR_SIZE=y this can make a huge difference in
      kernel image size (using a standard Fedora .config):
         text    data     bss     dec           hex filename
         5613924  562708 3854336 10030968    990f78 vmlinux.before
         5486689  562708 3854336  9903733    971e75 vmlinux.after
      that's a 2.3% text size reduction (!).

      x86: move defconfig files for i386 and x86_64 to x86 · 2266cfd5
      Sam Ravnborg authored
      With some small changes to kconfig makefile we can now
      locate the defconfig files for i386 and x86_64 in
      the configs/ subdirectory under x86.
      make ARCH=i386 defconfig and make defconfig
      works as expected also after this change.
      But arch maintainers shall now update a defconfig file in
      the configs/ directory.

      i386: Allow KVM on i386 nonpae · 2d9ce177
      Avi Kivity authored
      Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of
      the cmpxchg64b feature and enables compilation of the set_64bit() family.
      Since the option is dependent on PAE, and since KVM depends on set_64bit(),
      this effectively disables KVM on i386 nopae.
      Simplify by removing the config option altogether: the boot check is made
      dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed
      without constraints.  It is up to users to check for the feature flag (KVM
      does not as virtualiation extensions imply its existence).

      libata/IDE: remove combined mode quirk · 8cdfb29c
      Jeff Garzik authored
      Both old-IDE and libata should be able handle all controllers and
      devices found using normal resource reservation methods.
      This eliminates the awful, low-performing split-driver configuration
      where old-IDE drove the PATA portion of a PCI device, in PIO-only mode,
      and libata drove the SATA portion of the /same/ PCI device, in DMA mode.
      Typically vendors would ship SATA hard drive / PATA optical
      configuration, which would lend itself to slow (PIO-only) CD-ROM
      For Intel users running in combined mode, it is now wholly dependent on
      your driver choice (potentially link order, if you compile both drivers
      in) whether old-IDE or libata will drive your hardware.
      In either case, you will get full performance from both SATA and PATA
      ports now, without having to pass a kernel command line parameter.

      i386: turn on CONFIG_PNP in defconfig · 10fccf5f
      Bjorn Helgaas authored
      I'm trying to remove drivers/acpi/motherboard.c, which is mostly
      redundant with drivers/pnp/system.c.  So make sure that we include the
      PNP driver in the default config.  Most distros enable this already.
      Turning on CONFIG_PNP also causes the following options to be enabled:
      CONFIG_SERIAL_8250_PNP causes legacy serial ports to be discovered
      twice, which is ugly but harmless:
          serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
