      __initdata. The only caller of dmar_ir_support() is
intr_remapping_supported() also annotated with __init.

WARNING: drivers/pci/built-in.o(.text+0xa110): Section mismatch in
reference from the function dmar_ir_support() to the variable
.init.data:dmar_tbl
The function dmar_ir_support() references
the variable __initdata dmar_tbl.
This is often because dmar_ir_support lacks a __initdata
annotation or the annotation of dmar_tbl is wrong.

      When controlling an industrial radio modem it can be necessary to · 489cb7ee
      Dick Hollenbeck authored 
      manipulate the handshake lines in order to control the radio modem's
transmitter, from userspace.

The transmitter should not be turned off before all characters have been
transmitted.  serial8250_tx_empty() was reporting that all characters were
transmitted before they actually were.

===

Discovered in parallel with more testing and analysis by Kees Schoenmakers
as follows:

I ran into an NetMos 9835 serial pci board which behaves a little
different than the standard.  This type of expansion board is very common.

"Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together
with the "UART_LSR_THRE" bit when writing data to the device.

The NetMos device does it slightly different

I believe that the TEMT bit is coupled to the shift register.  The problem
is that after writing data to the device and very quickly after that one
does call serial8250_tx_empty, it returns the wrong information.

My patch makes the test more robust (and solves the problem) and it does
not affect the already correct devices.


Alan:

  We may yet need to quirk this but now we know which chips we have a
  way to do that should we find this breaks some other 8250 clone with
  dodgy THRE.

      Fit blackfin uart over sport driver into common uart inftrastructure. It · 98fa22a0
      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 · 1c096f53
      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.

      Implement memory accessor interface in the MTD layer which enables the · 6fb11f9e
      Sudhakar Rajashekhara authored 
      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.

      With the recent system-wide improvements on suspend/resume and EFI booting · 389ae644
      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.
