    VIDEO: Correct use of request_region/request_mem_region

    JuliaLawall authored ralfbaechle committed
    request_region should be used with release_region, not request_mem_region.
    
    Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c,
    the problem is actually the other way around; request_mem_region should be
    used instead of request_region.
    
    The semantic patch that finds/fixes this problem is as follows:

      [PATCH] rc32434_wdt: fix compilation failure
      [WATCHDOG] rc32434_wdt.c: use resource_size()
  9. modules: don't export section names of empty sections via sysfs

    Helge Deller authored committed
    On the parisc architecture we face for each and every loaded kernel module
    this kernel "badness warning":
      sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text'
      Badness at fs/sysfs/dir.c:487
    
    Reason for that is, that on parisc all kernel modules do have multiple
    .text sections due to the usage of the -ffunction-sections compiler flag
    which is needed to reach all jump targets on this platform.
    
    An objdump on such a kernel module gives:
    Sections:
    Idx Name          Size      VMA       LMA       File off  Algn
      0 .note.gnu.build-id 00000024  00000000  00000000  00000034  2**2
                      CONTENTS, ALLOC, LOAD, READONLY, DATA
      1 .text         00000000  00000000  00000000  00000058  2**0
                      CONTENTS, ALLOC, LOAD, READONLY, CODE
      2 .text.ac97_bus_match 0000001c  00000000  00000000  00000058  2**2
                      CONTENTS, ALLOC, LOAD, READONLY, CODE
      3 .text         00000000  00000000  00000000  000000d4  2**0
                      CONTENTS, ALLOC, LOAD, READONLY, CODE
    ...
    Since the .text sections are empty (size of 0 bytes) and won't be
    loaded by the kernel module loader anyway, I don't see a reason
    why such sections need to be listed under
    /sys/module/<module_name>/sections/<section_name> either.
    
    The attached patch does solve this issue by not exporting section
    names which are empty.

    [ARM] pxamci: call mmc_remove_host() before freeing resources

    zonque authored ericmiao committed
    mmc_remove_host() will cause the mmc core to switch off the bus power by
    eventually calling pxamci_set_ios(). This function uses the regulator or
    the GPIO which have been freed already.
    
    This causes the following Oops on module unload.

  20. rtc-x1205: fix rtc_time to y2k register value conversion

    Johannes Weiner authored committed
    The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's
    tm_year is in years since 1900.
    
    The function translating rtc_time to register values assumes tm_year to be
    years since first christmas, though, and we end up storing 0 or 1 in the
    CCR_Y2K register, which the hardware does not refuse to do.
    
    A subsequent probing of the clock fails due to the invalid value range in
    the register, though.
    
    [ And if it didn't, reading the clock would yield a bogus year because
      the function translating registers to tm_year is assuming a register
      value of 19 or 20. ]
    
    This fixes the conversion from years since 1900 in tm_year to the
    corresponding CCR_Y2K value of 19 or 20.

    a. Screen misalignment during booting when frame buffer console is
       enabled.
    
    b. Driver was configured always in PSEUDOCOLOR mode.  This patch
       dynamically configures the driver either in PSEUDOCOLOUR or TRUECOLOR
       mode depending on bpp.
    
    c. The RED and BLUE offsets were interchanged resulting in wrong
       bootup logo colour.
    
    This patch has been tested on DA830/OMAP-L137 and DA850/OMAP-L138 EVMs.

    MIPS: Loongson: Switch from flatmem to sparsemem

    lzufalcon authored ralfbaechle committed
    With flatmem hibernation for Loongson will fail, and there are also some
    other problems such as broken files when using NFS or CIFS / Samba.
    
    The config help of sparsemem says:
    
    "This option provides some potential performance benefits, along with
    decreased code complexity."
    
    So to avoid the potential problems of FLATMEM, we disable FLATMEM directly
    and use SPARSEMEM instead.

    MIPS: Loongson: Disallow 4kB pages

    lzufalcon authored ralfbaechle committed
    Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on:
    
    Kernel panic - not syncing: Attempted to kill init!
    
    The possible reason is the cache aliases problem:
    
    Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger
    then 4kb. so, If using 4kb page size, there is cache aliases problem.
    To avoid this kind of problem, extra cache flushing.  The 2nd possible
    solution is 16kb page size which avoids cache aliases without the need for
    extra cache flushes.  So we disable 4kB pages until the aliasing issue is
    solved.

    MIPS: Fix build error if __xchg() is not getting inlined.

    ralfbaechle authored
    If __xchg() is not getting inlined the outline version of the function
    will have a reference to __xchg_called_with_bad_pointer() which does not
    exist remaining.  Fixed by using BUILD_BUG_ON() to check for allowable
    operand sizes.
