* sh: HAVE_IOREMAP_PROT depends on MMU.Paul Mundt2008-09-17
| | | | | | | | | HAVE_IOREMAP_PROT enables an unconditional reference to generic_access_phys(), which remains undefined in the nommu case. As there's no point in supporting this there anyways, simply fix up the dependency. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Derive calibrate_delay lpj from clk fwk.Paul Mundt2008-09-08
| | | | | | | | | | | | All CPUs must have a sensible cpu_clk definition these days, which we can safely use for deriving the preset loops_per_jiffy. The only odd one out is SH-5, which hasn't been hammered in to the framework yet. Based on the ST patch.

* sh: Disable seccomp support by default.Paul Mundt2008-09-07
| | | | | | | This was initially checked in with a stupid default of y, while most everyone is going to want to have this disabled anyways. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add kprobes support.Chris Smith2008-09-07

* sh: Don't enable clockevents broadcasting on UP SH-X3 builds.Paul Mundt2008-09-07
| | | | | | | Fixes up compile errors with missing timer definitions. It's pointless to have this enabled anyways if CONFIG_SMP=n. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: generic clockevent broadcast support.Paul Mundt2008-09-07
| | | | | | | | This hooks up GENERIC_CLOCKEVENTS_BROADCAST and a dummy local timer, which we call in to from the timer IPI when no other local timer is provided. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off ARCH_SUPPORTS_AOUT and remnants of a.out support.Paul Mundt2008-08-04
| | | | | | | | SH never really supported a.out, so this was all just copied over blindly from x86 way back when. As we don't reference linux/a.out.h anywhere in the tree, these can now safely be killed off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: define GENERIC_HARDIRQS_NO__DO_IRQ.Paul Mundt2008-08-04
| | | | | | | We haven't called in to __do_IRQ() in a long time, so it seems like a reasonable time to switch this on by default. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: define GENERIC_LOCKBREAK.Paul Mundt2008-08-04

| * add HAVE_CLK to Kconfig, for driver dependenciesDavid Brownell2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flag platforms as HAVE_CLK (or not) in Kconfig, based on whether they support <linux/clk.h> calls, so that otherwise portable drivers which need those calls can list that dependency. Something like this is a prerequisite for merging the musb_hdrc driver, currently used on platforms including Davinci, OMAP2430, OMAP3xx ... and the discrete TUSB6010 chip, which doesn't have a natural platform dependency.

* sh: trapped io support V2Magnus Damm2008-02-14
| | | | | | | | | | | | | | | | | | | The idea is that we want to get rid of the in/out/readb/writeb callbacks from the machvec and replace that with simple inline read and write operations to memory. Fast and simple for most hardware devices (think pci). Some devices require special treatment though - like 16-bit only CF devices - so we need to have some method to hook in callbacks. This patch makes it possible to add a per-device trap generating filter. This way we can get maximum performance of sane hardware - which doesn't need this filter - and crappy hardware works but gets punished by a performance hit. V2 changes things around a bit and replaces io access callbacks with a simple minimum_bus_width value. In the future we can add stride as well.

| | | | | | | | | | | | | | | | | | | Mark arches that support A.OUT format by including the following in their master Kconfig files: config ARCH_SUPPORTS_AOUT def_bool y This should also be set if the arch provides compatibility A.OUT support for an older arch, for instance x86_64 for i386 or sparc64 for sparc. I've guessed at which arches don't, based on comments in the code, however I'm sure that some of the ones I've marked as 'yes' actually should be 'no'.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linus: On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Changelog: Actually, I know I gave this as the magic incantation, but now that I see it, I realize that I should have told you to just use config ARCH_SUPPORTS_KPROBES def_bool y instead, which is a bit denser. We seem to use both kinds of syntax for these things, but this is really what "def_bool" is there for... Changelog : - Moving to HAVE_*. - Add AVR32 oprofile.
