[CPUFREQ] Geode register fixes.
From: Hiroshi Miura <miura at da-cha.org>
I mistook a Geode chipset's register meanings. (-.-;
ON is not 'CPU is ON' but 'cpu modulation is ON' that is stops cpu.
this causes a bad freq setting.
This patch fixes this and minor bug that is,
if (new_khz == stock_freq) { /* if new khz == 100% of CPU speed, it is special case */
local_irq_save(flags);
cpufreq_notify_transition(&freqs, CPUFREQ_PRECHANGE);
cpufreq_notify_transition() called after local_irq_save();
this makes not update cpu_khz.

[PATCH] dm: block size bug with 64 bit devs
With 32 bit sector_t the block device size _in bytes_ is also cut to
32 bit in __set_size when the block device is mount (a filesystem
mounted). The argument should be cast to loff_t before expanding the
sector count to a byte count and calling i_size_write.

[PATCH] DVD-R capability flag set incorrectly, /proc formatting fix
From John McKell <mckellj@iomega.com>:
This patch for scsi/sr.c and cdrom/cdrom.c persuades
/proc/sys/dev/cdrom/info to report that connecting a drive via USB
rather than ATAPI in fact does not make it able to write DVD-R.
Without this patch, when sr0 and hdd are the same type of device
connected via USB and ATAPI respectively, I see:
$ cat /proc/sys/dev/cdrom/info:
drive name: sr1 sr0 hdd
...
Can write CD-R: 1 0 0
Can write CD-RW: 1 0 0
Can read DVD: 0 0 0
Can write DVD-R: 1 1 0
Can write DVD-RAM: 0 0 0
Can read MRW: 0 0 0
Can write MRW: 0 0 0
With this patch applied, instead I see:
$ cat /proc/sys/dev/cdrom/info:
drive name: sr1 sr0 hdd
...
Can write CD-R: 1 0 0
Can write CD-RW: 1 0 0
Can read DVD: 0 0 0
Can write DVD-R: 0 0 0
Can write DVD-RAM: 0 0 0
Can read MRW: 0 0 0
Can write MRW: 0 0 0
The sr1 device in particular is an ordinary CD-RW that in fact cannot
write DVD-R.
While messing with this code, I also thought to tweak the /proc
formatting to align the tabbed columns.
Here's a new version of the patch according to our discussion.
This allows the platform to add its own platform files to the
sysfs PCI device node through a "pcibios_add_platform_entries()"
call.
I added an empty pcibios_add_platform_entries() inline to all
archs that apparently have PCI and implemented the OF stuff for
ppc and ppc64. The name is still "devspec" for now, I doubt
it will conflict and that's consistent with our use of the
"devspec" name in other places.

[PATCH] getxattr error checking fix
From: Nathan Scott <nathans@sgi.com>,
Andreas Gruenbacher <agruen@suse.de>
XFS regression tests tripped a couple of problems with the recent xattr fix.
When a size of 0 is passed in, the getxattr and listxattr syscalls return the
size that would be required for the value or list of names, without actually
returning the value. The previous patch accidentally removed this test, and
so querying the required size broke.

This is a new ported driver, fscher, which supports the FSC Hermes chip.
The original driver was written by Reinhard Nissl, who also ported it to
Linux 2.6, as discussed on the lm_sensors mailing list during the last
two weeks. I reviewed the code and we made the necessary changes, so
that what we have now looks good to me. Please apply on top of your i2c

[PATCH] USB: re-factor enumeration/reset paths
This patch starts dis-entangling some of the enumeration logic by
moving initialization code into the usb_alloc_dev() constructor.
Some call signatures changed; a usbcore-internal declaration was
moved in <linux/usb.h> to a more appropriate location.
With the driver model init now more centralized, it's safer to
use driver model calls (including dev_info) a lot earlier, so
the "new device at address N" message now does that. It also
reports the device speed, which may not be evident otherwise.
PC300 MLPPP support is currently marked broken in 2.6.x.
To fix that, attached patch implements tiocmset/tiocmget methods on the
pc300_tty.c driver, which is the new method tty drivers are supposed to
use instead ioctl.
This fixes two related issues in the ioctl handler:
- ioctl requesting RTS signal would affect DTR signal
- The RTS signal is now handled.
[PATCH] fix OOPS for multiple IDE PCI modules and CONFIG_PROC_FS=y
The problem is that when loading next IDE PCI module memory used by
previously registered ide_pci_host_proc_list entry is already unmapped
(because of __{dev}initdata). This doesn't happen in built-in case
because this memory is freed after all drivers are initialized.
Fix it by removing __{dev}initdata from all ide_pci_host_proc_t.
Thanks to Andre Tomt <andre@tomt.net> for help in debugging this.
