Paul Mackerras points out that doing the _raw_spin_trylock each time
through the loop will generate tons of unnecessary bus traffic.
Instead, after we fail to get the lock we should poll it with simple
loads until we see that it is clear and then retry the atomic op. 
Assuming a reasonable cache design, the loads won't generate any bus
traffic until another cpu writes to the cacheline containing the lock.

Agreed.

We don't set GENHD_FL_REMOVABLE because this flag indicates that
the media may be removed while the block device persists.  Since
MMC destroys the block device when the card (media + on-board
controller) is removed, the block device will never exist without
media present.  Therefore, setting GENHD_FL_REMOVABLE would be
misleading.

Patch from Ben Dooks

Update to the s3c2410/s3c2440 clock code to use
the naming conventions now used throughout the
arch/arm/mach-s3c2410/ directory, as well as
a re-organisation of the initialisation of the
clocks.
The previous method was to initialise the clocks
as part of the function that initialised the
statically mapped IO regions, which was called
from the machine initialisation. This proves
a problem if the machine initialisation needs
to use these IO areas to determine the frequency
of PLL crystal fitted.
This patch makes the following changes:
 - s3c2410_init_clocks renamed s3c24xx_setup_clocks
 - s3c2410_clkcon_enable renamed s3c24xx_clk_enable
 - s3c2410_register_clock renamed s3c24xx_register_clock
 - cpu specific init_clocks to be called from cpu.c
 - add s3c24xx_init_clocks for machine init to call
 - split the cpu specific clock code from xxx_map_io
 - update all machine initialisation methods
and the following changes as cleanup which should
have been caught by previous patches:
 - remove s3c2440_hdiv (unused)
 - remove s3c2440_clock_tick_rate (unused)

Doing some raid testing threw a bug in the scsi mid layer, because the
segment counts wasn't correct.  Initially I worried that we still had
problems in this area, but it turns out that is due to the raid usage of
bio clones.  Currently you have to hold on to the original bio as well,
since the clone only maintains a pointer to the bio_vec inside the
original bio.  If the original bio is freed first, the clone will have
garbage in its bio->bi_io_vec as soon as that memory is scribbled.

I think the best fix is to maintain flexibility and duplicate the io_vec
inside the clone as well. Attached patch does this.

Patch from Lothar Wassmann

Hi,
ioremapping a memory range that ends on the first byte of a page
(e.g. mapping PAGE_SIZE + 1 bytes on a page boundary) results in a
mapping that is one page too short. In particular trying to create a 1
byte mapping at the start of a page results in a BUG_ON() assertion in
remap_area_pages() because the calculated mapping size is zero.
