a885c8c431 [PATCH] Add block_device_operations.getgeo block device method
HDIO_GETGEO is implemented in most block drivers, and all of them have to
duplicate the code to copy the structure to userspace, as well as getting
the start sector.  This patch moves that to common code [1] and adds a
->getgeo method to fill out the raw kernel hd_geometry structure.  For many
drivers this means ->ioctl can go away now.

[1] the s390 block drivers are odd in this respect.  xpram sets ->start
    to 4 always which seems more than odd, and the dasd driver shifts
    the start offset around, probably because of it's non-standard
    sector size.

de25968cc8 [PATCH] fix more missing includes
Include fixes for 2.6.14-git11.  Should allow to remove sched.h from
module.h on i386, x86_64, arm, ia64, ppc, ppc64, and s390.  Probably more
to come since I haven't yet checked the other archs.

0fec53a24a [ARM] Remove EPXA10DB machine support
EPXA10DB seems to be uncared for:
- the "PLD" code has never been merged
- no one has reported that this platform has been broken since
  at least 2.6.10
- interest seems to have dried up around March 2003.

Therefore, remove EPXA10DB support.

f8cfa618dc [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback
Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:

        int (*probe)            (struct pcmcia_device *dev);
        void (*remove)          (struct pcmcia_device *dev);

        int (*suspend)          (struct pcmcia_device *dev);
        int (*resume)           (struct pcmcia_device *dev);

987d24018d [MTD] CFI: Use 16-bit access to autoselect/read device id data
Recent models of Intel/Sharp and Spansion CFI flash now have significant
bits in the upper byte of device ID codes, read via what Spansion calls
"autoselect" and Intel calls "read device identifier".  Currently these
values are truncated to the low 8 bits in the mtd data structures, as
all CFI read query info has previously been read one byte at a time.
Add a new method for reading 16-bit info, currently just manufacturer
and device codes; datasheets hint at future uses for upper bytes in
other fields.

This patch removes almost all inclusions of linux/version.h.  The 3
#defines are unused in most of the touched files.

A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.

There are also lots of #ifdef for long obsolete kernels, this was not
touched.  In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

b95f9609c7 [MTD] chips cfi_cmdset_0002: Prevent timeout race
We've noticed that sometimes "MTD do_write_buffer(): software timeout"
message was printed out when writing to a Fujitsu NOR flash.
It turned out that this was because of a race in the timeout handling
do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and
sometimes if the timer interrupt handling takes more than one or even two
jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just
after chip_ready() call, the driver bails out from a ready polling loop
despite the chip has actually become ready while all those interrupts were
handled. To deal with this issue, extra check for chip ready is neccessary on
timeout expiration (and the checks should better be reordered).
As do_write_oneword() uses the same approach, it needs to also be changed.
