  • c5ec6fb08   [CRIS] Remove links from CRIS build ... Browse Code »

    Remove the links to architecture and machine dependent directories
    (boot, lib, drivers, arch, mach)

    The links were created and used mostly from the arch/cris/Makefile,
    so why not dispense with them altogether?
    Changed $(ARCH) to "cris" in Makefile, it is easier to read this way.

    The CRISv32 head.S common files for the kernel and compressed images
    needed to be modified to use ifdefs instead of using the now removed
    mach link. Since there are only two versions, this is not a huge loss
    in readability.

    The link to vmlinux.lds.S is also replaced with a merged version
    which uses ifdefs to select the correct layout.
    System.map before and after are identical.

  • 64ac24e73   Generic semaphore implementation ... Browse Code »
    46

    Semaphores are no longer performance-critical, so a generic C
    implementation is better for maintainability, debuggability and
    extensibility. Thanks to Peter Zijlstra for fixing the lockdep
    warning. Thanks to Harvey Harrison for pointing out that the
    unlikely() was unnecessary.

  • 7b275523a   cris build fixes: corrected and improved NMI and IRQ handling ... Browse Code »

    Corrects compile errors and the following:

    - Remove oldset parameter from do_signal and do_notify_resume.

    - Modified to fit new consolidated IRQ handling code.

    - Reverse check order between external nmi and watchdog nmi to avoid false
    watchdog oops in case of a glitch on the nmi pin.

    - Return from an pin-generated NMI the same way as for other interrupts.

    - Moved blocking of ethernet rx/tx irq from ethernet interrupt handler to
    low-level asm interrupt handlers. Fixed in the multiple interrupt
    handler also.

    - Add space for thread local storage in thread_info struct.

    - Add NO_DMA to Kconfig, and include arch specific Kconfig using arch
    independent path. Include subsystem Kconfigs for pcmcia, usb, i2c,
    rtc and pci.

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

    And then drop a few hunks which conflicted with outstanding work.

  • 8ef386092   [PATCH] kill wall_jiffies ... Browse Code »

    With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies.
    So we can kill wall_jiffies completely.

    This is just a cleanup and logically should not change any real behavior
    except for one thing: RTC updating code in (old) ppc and xtensa use a
    condition "jiffies - wall_jiffies == 1". This condition is never met so I
    suppose it is just a bug. I just remove that condition only instead of
    kill the whole "if" block.

    screen_info.h doesn't have anything to do with the tty layer and shouldn't be

    directly include screen_info.h. struct screen_info is mainly used to
    communicate with the console drivers in drivers/video/console. Note that this
    patch touches every arch and I have no way of testing it. If there is a
    mistake the worst thing that will happen is a compile error.

  • d1bef4ed5   [PATCH] genirq: rename desc->handler to desc->chip ... Browse Code »

    This patch-queue improves the generic IRQ layer to be truly generic, by adding
    various abstractions and features to it, without impacting existing
    functionality.

    While the queue can be best described as "fix and improve everything in the
    generic IRQ layer that we could think of", and thus it consists of many
    smaller features and lots of cleanups, the one feature that stands out most is
    the new 'irq chip' abstraction.

    The irq-chip abstraction is about describing and coding and IRQ controller
    driver by mapping its raw hardware capabilities [and quirks, if needed] in a
    straightforward way, without having to think about "IRQ flow"
    (level/edge/etc.) type of details.

    This stands in contrast with the current 'irq-type' model of genirq
    architectures, which 'mixes' raw hardware capabilities with 'flow' details.
    The patchset supports both types of irq controller designs at once, and
    converts i386 and x86_64 to the new irq-chip design.

    As a bonus side-effect of the irq-chip approach, chained interrupt controllers
    (master/slave PIC constructs, etc.) are now supported by design as well.

    The end result of this patchset intends to be simpler architecture-level code
    and more consolidation between architectures.

    We reused many bits of code and many concepts from Russell King's ARM IRQ
    layer, the merging of which was one of the motivations for this patchset.

    This patch:

    rename desc->handler to desc->chip.

    Originally i did not want to do this, because it's a big patch. But having
    both "desc->handler", "desc->handle_irq" and "action->handler" caused a
    large degree of confusion and made the code appear alot less clean than it
    truly is.

    I have also attempted a dual approach as well by introducing a
    desc->chip alias - but that just wasnt robust enough and broke
    frequently.

    So lets get over with this quickly. The conversion was done automatically
    via scripts and converts all the code in the kernel.

    This renaming patch is the first one amongst the patches, so that the
    remaining patches can stay flexible and can be merged and split up
    without having some big monolithic patch act as a merge barrier.

  • 894b5779c   [PATCH] No arch-specific strpbrk implementations ... Browse Code »

    While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't
    being exported from lib/string.c. Investigating further, I noticed a
    changeset that removed its export and added it to _ksyms.c on a few more
    architectures. The justification was that "other arches do it."

    I think this is wrong, since no architecture currently defines
    __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it
    themselves. Therefore, consolidate the export to lib/string.c.
