  • 7ddc83997   hexagon: delete __cpuinit usage from all hexagon files ... Browse Code »

    The __cpuinit type of throwaway sections might have made sense
    some time ago when RAM was more constrained, but now the savings
    do not offset the cost and complications. For example, the fix in
    commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
    is a good example of the nasty type of bugs that can be created
    with improper use of the various __init prefixes.

    After a discussion on LKML[1] it was decided that cpuinit should go
    the way of devinit and be phased out. Once all the users are gone,
    we can then finally remove the macros themselves from linux/init.h.

    Note that some harmless section mismatch warnings may result, since
    notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
    are flagged as __cpuinit -- so if we remove the __cpuinit from
    arch specific callers, we will also get section mismatch warnings.
    As an intermediate step, we intend to turn the linux/init.h cpuinit
    content into no-ops as early as possible, since that will get rid
    of these warnings. In any case, they are temporary and harmless.

    This removes all the arch/hexagon uses of the __cpuinit macros from
    all C files. Currently hexagon does not have any __CPUINIT used in
    assembly files.

  • 0c9885347   mm: concentrate modification of totalram_pages into the mm core ... Browse Code »

    Concentrate code to modify totalram_pages into the mm core, so the arch
    memory initialized code doesn't need to take care of it. With these
    changes applied, only following functions from mm core modify global
    variable totalram_pages: free_bootmem_late(), free_all_bootmem(),
    free_all_bootmem_node(), adjust_managed_page_count().

    With this patch applied, it will be much more easier for us to keep
    totalram_pages and zone->managed_pages in consistence.

    Pull removal of GENERIC_GPIO from Grant Likely:
    "GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any
    valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it
    is possible to do so which has been causing confusion and breakage.
    This branch does the work to completely eliminate GENERIC_GPIO."
