I no longer work at Bluewater Systems. Update my email address accordingly. I
have deleted my email address from C files rather than change it. This
was suggested by several people, since the commit from my new email
address will cause scripts/get_maintainer.pl to function properly. I
have not added the .mailmap entry as suggested by Joe because I think
it is no longer necessary if I touch all the files which had my name
in them.

The previous section mismatch fix for this driver wasn't entirely correct.
The sst25l_flash_info array is now used in the devinit probe func, but is
marked as initdata, so building results in the warning:
WARNING: drivers/mtd/devices/sst25l.o(.devinit.text): Section mismatch
in reference from the function sst25l_probe()
to the variable .init.data:sst25l_flash_info
Further, the remove func should be devexit rather than exit to match the
probe func.

Building the kernel with 'make CONFIG_DEBUG_SECTION_MISMATCH=y´
resulted in:
WARNING: vmlinux.o(.data+0x15938): Section mismatch in reference from
the variable sst25l_driver to the function .init.text:sst25l_probe()
The variable sst25l_driver references
the function __init sst25l_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
Fix the section mismatch.

The rest of the function assumes that "data" can be null. I don't know
the code well enough to say whether it can actually be null, but there
is no harm in checking here.

Some SPI masters (ep93xx) have limitations when using the SFRMOUT
signal for the spi device chip select. The SFRMOUT signal is
only asserted as long as the spi transmit fifo contains data. As
soon as the last bit is clocked into the receive fifo it gets
deasserted.
The functions sst25l_status and sst25l_match_device use the API
function spi_write_then_read to write a command to the flash then
read the response back. This API function creates a two part spi
message for the write then read. When this message is transferred
the SFRMOUT signal ends up getting deasserted after the command
phase. This causes the command to get aborted by the device so
the read phase returns invalid data.
By changing sst25l_status and sst25l_match_device to use a single
transfer synchronous message, the SFRMOUT signal stays asserted
during the entire message so the correct data always gets returned.
This change will have no effect on SPI masters which use a chip
select mechanism (GPIO's, etc.) which does stay asserted correctly.
As a bonus, the single transfer synchronous messages complete faster
than multi-part messages.

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.

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
