  • After experimenting with kexec with the last merges after 2.6.29, I've
    had some problems when probing e100. It would not read the eeprom. After
    some bisects, I realized this has been like that since forever (at least
    2.6.18). The problem is that shutdown is doing the same thing that
    suspend does and puts the device in D3 state. I couldn't find a way to
    get the device back to a sane state in the probe function. So, based on
    some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe,
    I wrote this one for e100.

  • The x_tables are organized with a table structure and a per-cpu copies
    of the counters and rules. On older kernels there was a reader/writer
    lock per table which was a performance bottleneck. In 2.6.30-rc, this
    was converted to use RCU and the counters/rules which solved the performance
    problems for do_table but made replacing rules much slower because of
    the necessary RCU grace period.

    This version uses a per-cpu set of spinlocks and counters to allow to
    table processing to proceed without the cache thrashing of a global
    reader lock and keeps the same performance for table updates.

  • Commit edada399 broke the build on 64-bit powerpc because it moved the
    __ftr_alt_* sections of a file away from the .text section, causing
    link failures due to relative conditional branch targets being too far
    away from the branch instructions. This happens on pretty much all
    64-bit powerpc configs.

    This change reverts commit edada399 while preserving the update from
    the *.refok sections to .ref.text that has happened since.

  • st driver uses blk_rq_map_user() in order to just build a request out
    of page frames. In this case, map_data->offset is a non zero value and
    iov[0].iov_base is NULL. We need to increase nr_pages for that.

  • hd dance around local irq and HD_IRQ enable without achieving much.
    It ends up transferring data from irq handler with both local irq and
    HD_IRQ disabled. The only place it actually does something is while
    transferring the first block of a request which it does with HD_IRQ
    disabled but local irq enabled.

    Unfortunately, the dancing is horribly broken from locking POV. IRQ
    and timeout handlers access block queue without grabbing the queue
    lock and running the driver in SMP configuration crashes the whole
    machine pretty quickly.

    Remove meaningless irq enable/disable dancing and add proper locking
    in issue, irq and timeout paths.

  • Default voltage constraints were being provided for fixed voltage
    regulator where board constraints were not provided but these constraints
    used INT_MIN as the default minimum voltage which is not a valid value
    since it is less than zero. Use 1uV instead.

    Also set the default values we set in the constraints themselves since
    otherwise the max_uV constraint we determine will not be stored in the
    actual constraint strucutre and will therefore not be used.

  • During regulator registration, any error after device_register() will
    cause a double-free on the struct regulator_dev 'rdev'. The bug is in
    drivers/regulator/core.c:regulator_register():

  • I removed the extra semi-colon and indented the return statement.

    The unreachable code was found by smatch (http://repo.or.cz/w/smatch.git).
    The patch was compile tested.
