  • The current h8300 GPIO implementation doesn't provide the standard GPIO
    API, and in fact provides only direction control rather than normal GPIO
    functionality. Currently this is only used by the platform interrupt
    implementation rather than by a range of drivers so in preparation for
    moving over to gpiolib move the header out of the way of the gpiolib
    header, allowing a default GPIO implementation to be provided.

    For actual use of these GPIOs with gpiolib a real driver would still need
    to be written but there appears to be no current need for this.

  • After changing all consumers of atomics to include , we
    ran into some compile time errors due to this dependency chain:

    linux/atomic.h
    -> asm/atomic.h
    -> asm-generic/atomic-long.h

    where atomic-long.h could use funcs defined later in linux/atomic.h
    without a prototype. This patches moves the code that includes
    asm-generic/atomic*.h to linux/atomic.h.

    Archs that need need to select
    CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it
    unconditionally).

    Compile tested on i386 and x86_64 with allnoconfig.

  • All these are instances of
    #define NAME value;
    or
    #define NAME(params_opt) value;

    These of course fail to build when used in contexts like
    if(foo $OP NAME)
    while(bar $OP NAME)
    and may silently generate the wrong code in contexts such as
    foo = NAME + 1; /* foo = value; + 1; */
    bar = NAME - 1; /* bar = value; - 1; */
    baz = NAME & quux; /* baz = value; & quux; */

    Reported on comp.lang.c,
    Message-ID:
    Initial analysis of the dangers provided by Keith Thompson in that thread.

    There are many more instances of more complicated macros having unnecessary
    trailing semicolons, but this pile seems to be all of the cases of simple
    values suffering from the problem. (Thus things that are likely to be found
    in one of the contexts above, more complicated ones aren't.)

  • * setns:
    ns: Wire up the setns system call

    Done as a merge to make it easier to fix up conflicts in arm due to
    addition of sendmmsg system call

    Linus Torvalds
     
  • 32bit and 64bit on x86 are tested and working. The rest I have looked
    at closely and I can't find any problems.

    setns is an easy system call to wire up. It just takes two ints so I
    don't expect any weird architecture porting problems.

    While doing this I have noticed that we have some architectures that are
    very slow to get new system calls. cris seems to be the slowest where
    the last system calls wired up were preadv and pwritev. avr32 is weird
    in that recvmmsg was wired up but never declared in unistd.h. frv is
    behind with perf_event_open being the last syscall wired up. On h8300
    the last system call wired up was epoll_wait. On m32r the last system
    call wired up was fallocate. mn10300 has recvmmsg as the last system
    call wired up. The rest seem to at least have syncfs wired up which was
    new in the 2.6.39.

    v2: Most of the architecture support added by Daniel Lezcano
    v3: ported to v2.6.36-rc4 by: Eric W. Biederman
    v4: Moved wiring up of the system call to another patch
    v5: ported to v2.6.39-rc6
    v6: rebased onto parisc-next and net-next to avoid syscall conflicts.
    v7: ported to Linus's latest post 2.6.39 tree.

  • minix bit operations are only used by minix filesystem and useless by
    other modules. Because byte order of inode and block bitmaps is different
    on each architecture like below:

    m68k:
    big-endian 16bit indexed bitmaps

    h8300, microblaze, s390, sparc, m68knommu:
    big-endian 32 or 64bit indexed bitmaps

    m32r, mips, sh, xtensa:
    big-endian 32 or 64bit indexed bitmaps for big-endian mode
    little-endian bitmaps for little-endian mode

    Others:
    little-endian bitmaps

    In order to move minix bit operations from asm/bitops.h to architecture
    independent code in minix filesystem, this provides two config options.

    CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k.
    CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use
    native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu,
    m32r, mips, sh, xtensa). The architectures which always use little-endian
    bitmaps do not select these options.

    Finally, we can remove minix bit operations from asm/bitops.h for all
    architectures.

  • The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
    is used to configure any non-standard kernel with a much larger scope than
    only small devices.

    This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
    references to the option throughout the kernel. A new CONFIG_EMBEDDED
    option is added that automatically selects CONFIG_EXPERT when enabled and
    can be used in the future to isolate options that should only be
    considered for embedded systems (RISC architectures, SLOB, etc).

    Calling the option "EXPERT" more accurately represents its intention: only
    expert users who understand the impact of the configuration changes they
    are making should enable it.
