  • Remove the now empty arch_reset() from all the mach/system.h includes,
    and remove its callsite. Remove arm_machine_restart() as this function
    no longer does anything useful.

    For samsung platforms, remove the include of mach/system-reset.h and
    plat/system-reset.h from their respective mach/system.h headers as these
    just define their arch_reset functions. As a result, the s3c2410 and
    plat-samsung system-reset.h files are no longer referenced, so remove
    these files entirely.

  • Some platforms (like OMAP not to name it) are doing rather complicated
    hacks just to determine the base UART address to use. Let's give their
    addruart macro some slack by providing an extra work register which will
    allow for much needed cleanups.

    This is basically a no-op as this commit is only adding the extra argument
    to the macro but no one is using it yet.

  • Aside of the usual motivation for constification, this function has a
    history of being abused a hook for interrupt and other fixups so I turned
    this function const ages ago in the MIPS code but it should be done
    treewide.

    Due to function pointer passing in varous places a few other functions
    had to be constified as well.

  • Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow
    multi-platform builds. This also removes the requirement for a platform to
    have a mach/hardware.h.

    The default values for i/o and mem are 0x1000 and 0x01000000, respectively.
    Per Arnd Bergmann, other values are likely to be incorrect, but this commit
    does not try to address that issue.

  • Since we're now using addruart to establish the debug mapping, we can
    remove the io_pg_offst and phys_io members of struct machine_desc.

    The various declarations were removed using the following script:

    grep -rl MACHINE_START arch/arm | xargs \
    sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

  • Rather than checking the MMU status in every instance of addruart, do it
    once in kernel/debug.S, and change the existing addruart macros to
    return both physical and virtual addresses. The main debug code can then
    select the appropriate address to use.

    This will also allow us to retreive the address of a uart for the MMU
    state that we're not current in.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • OMAP wishes to pass state to the boot loader upon reboot in order to
    instruct it whether to wait for USB-based reflashing or not. There is
    already a facility to do this via the reboot() syscall, except we ignore
    the string passed to machine_restart().

    This patch fixes things to pass this string to arch_reset(). This means
    that we keep the reboot mode limited to telling the kernel _how_ to
    perform the reboot which should be independent of what we request the
    boot loader to do.

  • When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
    so there's no point in publishing the prototypes via asm/dma.h, nor
    including the machine dependent parts of that API.

    This allows us to remove a lot of mach/dma.h files which don't contain
    any useful code. Unfortunately though, some platforms put their own
    private non-ISA definitions into mach/dma.h, so we leave these behind
    and fix the appropriate #include statments.

  • Let's provide an overridable default instead of having every machine
    class define __virt_to_bus and __bus_to_virt to the same thing. What
    most platforms are using is bus_addr == phys_addr so such is the default.

    One exception is ebsa110 which has no DMA what so ever, so the actual
    definition is not important except only for proper compilation. Also
    added a comment about the special footbridge bus translation.

    Let's also remove comments alluding to set_dma_addr which is not
    (and should not) be commonly used.
