  • 824122a31   MIPS: DEC/SNI: O32 wrapper stack switching fixes ... Browse Code »

    Commit 231a35d37293ab88d325a9cb94e5474c156282c0 [[MIPS] RM: Collected
    changes] broke DECstation support by introducing an incompatible copy of
    arch/mips/dec/prom/call_o32.S in arch/mips/fw/lib/, built unconditionally.
    The copy happens to land earlier of the two among the modules used in the
    link and is therefore chosen for the DECstation rather than the intended
    original. As a result random kernel data is corrupted because a pointer
    to the "%s" formatted output template is used as a temporary stack pointer
    rather than being passed down to prom_printf. This also explains why
    prom_printf still works, up to a point -- the next argument is the actual
    string to output so it works just fine as the output template until enough
    kernel data has been corrupted to cause a crash.

    This change adjusts the modified wrapper in arch/mips/fw/lib/call_o32.S to
    let callers request no stack switching by passing a null temporary stack
    pointer in $a1, reworks the DECstation callers to work with the updated
    interface and removes the old copy from arch/mips/dec/prom/call_o32.S. A
    few minor readability adjustments are included as well, most importantly
    O32_SZREG is now used throughout where applicable rather than hardcoded
    multiplies of 4 and $fp is used to access the argument save area as a more
    usual register to operate the stack with rather than $s0.

    Finally an update is made to the temporary stack space used by the SNI
    platform to guarantee 8-byte alignment as per o32 requirements.

  • 3b2663ca8   mips: delete non-required instances of include <linux/init.h> ... Browse Code »

    None of these files are actually using any __init type directives
    and hence don't need to include . Most are just a
    left over from __devinit and __cpuinit removal, or simply due to
    code getting copied from one driver to the next.

    The write() prototype expects a const char * as argument so declare
    it as such.

    Fixes the following build problem:

    arch/mips/sibyte/common/cfe_console.c:23:5: error: passing argument 2 of
    'cfe_write' discards 'const' qualifier from pointer target type [-Werror]

  • 0e2794b0b   MIPS: Kconfig: Rename several firmware related config symbols. ... Browse Code »

    With the upcoming merge of the ARC architecture there is a small likelyhood
    of conflicting use for the CONFIG_ARC config symbol. Rename it to
    CONFIG_FW_ARC. Also rename CONFIG_ARC32 to CONFIG_FW_ARC32, CONFIG_ARC64
    to CONFIG_FW_ARC64.

    For consistence also rename CONFIG_SNIPROM to CONFIG_FW_SNIPROM and
    CONFIG_CFE to CONFIG_FW_CFE.

    Using a cross-compiler to fix another issue, the following build error
    occurred for mips defconfig:

    arch/mips/fw/arc/misc.c: In function 'ArcHalt':
    arch/mips/fw/arc/misc.c:25:2: error: implicit declaration of function 'local_irq_disable'

    Fix it up by including irqflags.h.

    Pull "Disintegrate and delete asm/system.h" from David Howells:
    "Here are a bunch of patches to disintegrate asm/system.h into a set of
    separate bits to relieve the problem of circular inclusion
    dependencies.

    I've built all the working defconfigs from all the arches that I can
    and made sure that they don't break.

    The reason for these patches is that I recently encountered a circular
    dependency problem that came about when I produced some patches to
    optimise get_order() by rewriting it to use ilog2().

    This uses bitops - and on the SH arch asm/bitops.h drags in
    asm-generic/get_order.h by a circuituous route involving asm/system.h.

    The main difficulty seems to be asm/system.h. It holds a number of
    low level bits with no/few dependencies that are commonly used (eg.
    memory barriers) and a number of bits with more dependencies that
    aren't used in many places (eg. switch_to()).

    These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

    Move memory barriers here. This already done for MIPS and Alpha.

    (2) asm/switch_to.h

    Move switch_to() and related stuff here.

    (3) asm/exec.h

    Move arch_align_stack() here. Other process execution related bits
    could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

    Move xchg() and cmpxchg() here as they're full word atomic ops and
    frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

    Move die() and related bits.

    (6) asm/auxvec.h

    Move AT_VECTOR_SIZE_ARCH here.

    Other arch headers are created as needed on a per-arch basis."

    Fixed up some conflicts from other header file cleanups and moving code
    around that has happened in the meantime, so David's testing is somewhat
    weakened by that. We'll find out anything that got broken and fix it..
