      Fit blackfin uart over sport driver into common uart inftrastructure. It · 855d8f84
      sonic zhang authored 
      is based on the early platform interfaces to get the platform data early
when the console is initilized.

1. Enable sport uart driver to change uart baud, data bit, stop bit at
   runtime.  Bind the index of uart device nodes to physical index of
   sports.

2. Move all platform data into arch specific board files.  Register
   and probe platform device data in both early and normal stages.

3. Console is registered in sport uart driver as well.

4. Remove 500 us block waiting in sport tx stop code by putting a
   dummy data into tx fifo to make sure the sport tx stops when all bytes
   are shifted out except for the dummy data.

5. clean up a bit and fix up coding style.

      Work around one problem with my Acer Bluetooth Optical Rechargeable Mouse · 2f89b8bd
      Lamarque Vieira Souza authored 
      where the cursor gets stuck at screen's upper-left corner.

Even my notebook's touchpad is not able to move cursor when the bluetooth
mouse is connected to my Acer Ferrari 4005 notebook.

Using input session instead of hid session solves this problem although
the cursor still moves a little sluggishly with the bluetooth mouse,
cursor moves correctly using the touchpad.

My bluetooth mouse used to work well (no sluggish) until kernel 2.6.21,
since then the problems are getting worse with each kernel release (it got
sluggish in 2.6.22 and this this upper-left corner problem appeared in
2.6.28 or 2.6.27).

The patch adds a general quirk handling framework to the HIDP core and
then uses this framework to implement a quirk for this device.

      -- even if it was passed an MMIO address.  Fix this by claiming/releasing
all PCI resources in the PCI driver probe/remove handlers instead and get
rid of the must_free_region flag weirdness (why would Cardbus claim
anything for us?).

Also, the remove handler was trying to talk to the chip after having
disabled its address decoders (at least on x86) -- fix this and get rid of
useless VORTEX_PCI() calls.

While at it, fix some cases of the overly indented code...

      Implement memory accessor interface in the MTD layer which enables the · fdfaf855

      kernel to access flash data.

This patch adds two new members to the mtd_partition structure, a function
handler which will be called during setup of the partition and an argument
to be passed to this setup function.

Example:
+static struct mtd_partition spi_flash_partitions[] = {
+       [0] = {
+               .name       = "U-Boot",
+               .offset     = 0,
+               .size       = SZ_256K,
+               .mask_flags = MTD_WRITEABLE,
+       },
+       [1] = {
+               .name       = "U-Boot Environment",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_64K,
+               .mask_flags = MTD_WRITEABLE,
+       },
+       [2] = {
+               .name       = "Linux",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_7M,
+               .mask_flags = 0,
+       },
+       [3] = {
+               .name       = "MAC Address",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_64K,
+               .mask_flags = 0,
+               .setup      = davinci_get_mac_addr,
+               .context    = (void *)0,
+       },
+};

The davinci_get_mac_addr function reads the MAC address from
offset ZERO of last MTD partition.

      This adds CROSS_COMPILE as a kconfig string so you can store it in · 68134294
      Roland McGrath authored 
      .config.  Then you can use plain "make" in the configured kernel build
directory to do the right cross compilation without setting the
command-line or environment variable every time.

With this, you can set up different build directories for different kernel
configurations, whether native or cross-builds, and then use the simple:

	make -C /build/dir M=module-source-dir

idiom to build modules for any given target kernel, indicating which one
by nothing but the build directory chosen.

I tried a version that defaults the string with env="CROSS_COMPILE" so
that in a "make oldconfig" with CROSS_COMPILE in the environment you can
just hit return to store the way you're building it.  But the kconfig
prompt for strings doesn't give you any way to say you want an empty
string instead of the default, so I punted that.

      With the recent system-wide improvements on suspend/resume and EFI booting · 9c2e137f
      Henrik Rydberg authored 
      the suspend_resume method of the bcm5974 has broken.  When waking up from
the S3 state on the MacBookAir, the trackpad is found in a yet unknown
state, unable to switch to the proper multitouch mode.  The result is a
frozen touchpad, and a flood of errors of the kind

bcm5974: bad trackpad package, length: 8.

This patch retracts the reset_resume method altogether, falling back on
the generic unbind/rebind functionality of the usb layer until further
investigations can be made as how to reset the device when booting from
efi.

      The Collaborative Memory Manager (CMM) module allocates individual pages · 4991cbe3
      Robert Jennings authored 
      over time that are not migratable.  On a long running system this can
severely impact the ability to find enough pages to support a hotplug
memory remove operation.

This patch adds a memory isolation notifier and a memory hotplug notifier.
The memory isolation notifier will return the number of pages found in
the range specified.  This is used to determine if all of the used pages
in a pageblock are owned by the balloon (or other entities in the notifier
chain).  The hotplug notifier will free pages in the range which is to be
removed.  The priority of this hotplug notifier is low so that it will be
called near last, this helps avoids removing loaned pages in operations
that fail due to other handlers.

CMM activity will be halted when hotplug remove operations are active and
resume activity after a delay period to allow the hypervisor time to
adjust.

      Memory balloon drivers can allocate a large amount of memory which is not · b141d0ae
      Robert Jennings authored 
      movable but could be freed to accomodate memory hotplug remove.

Prior to calling the memory hotplug notifier chain the memory in the
pageblock is isolated.  Currently, if the migrate type is not
MIGRATE_MOVABLE the isolation will not proceed, causing the memory removal
for that page range to fail.

Rather than failing pageblock isolation if the migrateteype is not
MIGRATE_MOVABLE, this patch checks if all of the pages in the pageblock,
and not on the LRU, are owned by a registered balloon driver (or other
entity) using a notifier chain.  If all of the non-movable pages are owned
by a balloon, they can be freed later through the memory notifier chain
and the range can still be isolated in set_migratetype_isolate().
