account_steal_time called for idle doesn't work correctly:
1) steal time while idle needs to be added to the system time of idle
   to get correct uptime numbers
3) if there is an i/o request outstanding the steal time should be
   added to iowait, even if the hypervisor scheduled another virtual
   cpu since we are still waiting for i/o.
2) steal time while idle without an i/o request outstanding has to
   be added to cpustat->idle and not to cpustat->system.

Use a "pipe_buf_operations" structure to describe the ops that
can be done on a pipe buffer, so that pipe buffers from different
sources can have their own rules.

Right now the rules are just about how you map the buffers into
kernel virtual memory space, and how to release them (and whether
you can append new data to the end of an existing buffer).

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)

With 2.6.10-mm2 (or even with -mm1) some structures in struct psb_s have been
renamed in powernow-k8.h, but the renaming has not been done properly for all
occurences in powernow-k8.c.
This prevents cpufreq from accepting the BIOS PST-tables.

in powernow-k8.c, following the definition in the powernow-k8.h header file.

dbs_timer_init() will schedule_work(&dbs_work) so that do_dbs_timer()
is likely called very early at same time slice scheduler, and
for each cpu, dbs_check_cpu(cpu) will be called, likely at the same time
slice than dbs_timer_init().
So far, we will get total_idle_ticks == idle_ticks == 0 unconditonaly,
and the processor will be put at full speed even though it's not needed
at startup.
