34e7dc6ca4 hwmon: (lm85) Implement the standard PWM frequency interface
Implement the standard PWM frequency interface: pwm[1-*]_freq in
units of 1 Hz, instead of the non-standard pwm[1-*]_auto_pwm_freq
in units of 0.1 Hz. The old naming was not only non-standard, it was
also confusing, because it suggested that the frequency value only
applied in automatic fan speed mode, which isn't true.

810ad7b62c hwmon: (ams) Convert to a new-style i2c driver
The legacy i2c binding model is phasing out, so the ams driver needs
to be converted to a new-style i2c driver. Here is a naive approach of
this conversion. Basically it is moving the i2c device creation from
the ams driver to the i2c-powermac driver. This should work, but I
suspect we could come up with something cleaner by declaring the i2c
device as part of the platform setup. This could be done later by
someone more familiar with openfirmware-based platforms than I am
myself.

One nice thing brought by this conversion is that the ams driver
should be loaded automatically on systems where is is needed (at
least when the I2C interface to the chip is used) providing
coldplug-aware user-space environment.

8677142710 block: fix nr_phys_segments miscalculation bug
This fixes the bug reported by Nikanth Karthikesan <knikanth@suse.de>:

http://lkml.org/lkml/2008/10/2/203

The root cause of the bug is that blk_phys_contig_segment
miscalculates q->max_segment_size.

blk_phys_contig_segment checks:

req->biotail->bi_size + next_req->bio->bi_size > q->max_segment_size

But blk_recalc_rq_segments might expect that req->biotail and the
previous bio in the req are supposed be merged into one
segment. blk_recalc_rq_segments might also expect that next_req->bio
and the next bio in the next_req are supposed be merged into one
segment. In such case, we merge two requests that can't be merged
here. Later, blk_rq_map_sg gives more segments than it should.

We need to keep track of segment size in blk_recalc_rq_segments and
use it to see if two requests can be merged. This patch implements it
in the similar way that we used to do for hw merging (virtual
merging).

0fc71e3d65 block: add partition attribute for partition number
With extended devt, finding out the partition number becomes a bit
more challenging as subtracting the minor number from that of the
parent device doesn't work anymore.  The only thing left is parsing
the partition name which is brittle and not exactly universal (some
have '-' between the device name and partition number while others
don't).  This patch introduced partition attribute which contains the
partition number of the device.  This should make finding partitions
and its index easier.

This problem and solution were suggested by H. Peter Anvin.

70a3075d40 FRV: Eliminate NULL test and memset after alloc_bootmem
As noted by Akinobu Mita in patch b1fceac2b9,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory.  Thus a NULL test or memset after calls to these
functions is unnecessary.

This was fixed using the following semantic patch.

cb76d5a4c4 FRV: Switch unaligned access to the packed-struct implementation
Switch unaligned access to the packed-struct implementation for BE accesses as
this reduces the size of the kernel a little.  LE still uses the byte shift.

Provide dma_map_page() for the NOMMU-mode FRV arch.

Also do some fixing on the comments attached to the various DMA functions for
both MMU and NOMMU mode FRV code.
