5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

c4a3987fa0 drivers/serial/sunsu.c: Correct use after free
The of_iounmap is at the out_unmap label, but at that point up has already
been freed.  The free cannot be moved to the out_unmap label, because that
label is reachable from cases where up should not be freed.  So the call to
of_iounmap is just duplicated, and the goto converted to a return.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

8d099d4446 serial: sh-sci: fix SH-Mobile SH breakage
The follwing commit breaks SH-Mobile on non-ARM platforms:
"8a77b8d serial: sh-sci: Support ARM-based SH-Mobile CPUs."

The commit assumed that CONFIG_ARCH_SHMOBILE only was set
on ARM platforms, but it turns out that this kconfig is also
set by all SH-based SoCs. Sh7724 and other older SH-Mobile
SoCs are all broken without this fix.

This patch converts the "defined(CONFIG_ARCH_SHMOBILE)" into
one "defined()" per SoC model - similar to existing SH code.

935050daad drivers/serial/sunsab.c: adjust the constant used to initialize the interrupt_mask0 fields
From: Julia Lawall <julia@diku.dk>

SAB82532_ISR0_TCD is declared in drivers/serial/subsab.h as relating to a
status register, while SAB82532_IMR0_TCD is declared in the same file as
relating to a mask register.  The latter seems more appropriate for the
interrupt_mask0 field, and follows the strategy for initializing this field
elsewhere in the same file.

Both SAB82532_ISR0_TCD and SAB82532_IMR0_TCD have the same value.

cdc592d5d4 serial: bfin_5xx: kgdboc should accept gdb break only when it is active
If we always check for gdb breaks even when it isn't active, we get false
positives on normal code and the system panics.

7ed43f6af8 serial: bfin_5xx: need to disable DMA TX interrupt too
If we don't disable the DMA TX channel, an inopportune timeout will
trigger the interrupt handler and may cause a dead lock with the spin_lock.

bbcd18d1b3 serial: imx: fix NULL dereference Oops when pdata == NULL
The platform code doesn't have to provide platform data to get sensible
default behaviour from the imx serial driver.

This patch does not handle NULL dereference in the IrDA case, which still
requires a valid platform data pointer (in imx_startup()/imx_shutdown()),
since I don't know whether there is a sensible default behaviour, or
should the operation just fail cleanly.

ac6ec5b1de serial: 8250_pci: add support for MCS9865 / SYBA 6x Serial Port Card
This patch is heavily based on an earlier patch found on the linux-serial
mailing list [1], written by Darius Augulis.

The previous incarnation of this patch only supported a 2x serial port
card.  I have added support for my SYBA 6x serial port card, and tested on
x86.

b5d228cc4f serial: copy UART properties of UPF_FIXED_TYPE ports provisioned using early_serial_setup
Augment the UPF_FIXED_TYPE logic, which currently applies to UART ports
provisioned using platform_device_register.

The suggested patch applies same logic into 'serial8250_register_ports',
making UART ports provisioned using early_serial_setup inherit their
properties from the uart_config entry.

ccf68e59e9 serial: fit blackfin uart over sport driver into common uart infrastructure
Fit blackfin uart over sport driver into common uart inftrastructure.  It
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.
