fully functional.

Thanks to Jake Crimmins from EVGA for providing the correct GPIO info.
Thanks to Alan Hagge for doing all the device testing.
Thanks to Greg Williamson for providing hardware for testing.

V4L/DVB (12100): em28xx: make sure the analog GPIOs are set if we used a card hint

In cases where the board had a default USB ID, we would not indentify the
board until after the call to em28xx_set_mode().  As a result, for those
boards the analog GPIOs were not being set before probing the i2c bus for
devices (the probe would occur with the GPIOs being all high).

Make a call to em28xx_set_mode() so that the GPIOs are set properly before
probing the i2c bus for devices.

This problem was detected with the EVGA inDtube, where the tvp5150 is not
powered on unless GPIO1 is pulled low.

Trond Myklebust [Mon, 22 Jun 2009 19:09:14 +0000 (15:09 -0400)]
NFSv4: Replace nfs4_path_walk() with VFS path lookup in a private namespace

As noted in the previous patch, the NFSv4 client mount code currently
has several limitations. If the mount path contains symlinks, or
referrals, or even if it just contains a '..', then the client code in
nfs4_path_walk() will fail with an error.

This patch replaces the nfs4_path_walk()-based lookup with a helper
function that sets up a private namespace to represent the namespace on the
server, then uses the ordinary VFS and NFS path lookup code to walk down the
mount path in that namespace.

VFS: Add VFS helper functions for setting up private namespaces

The purpose of this patch is to improve the remote mount path lookup
support for distributed filesystems such as the NFSv4 client.

When given a mount command of the form "mount server:/foo/bar /mnt", the
NFSv4 client is required to look up the filehandle for "server:/", and
then look up each component of the remote mount path "foo/bar" in order
to find the directory that is actually going to be mounted on /mnt.
Following that remote mount path may involve following symlinks,
crossing server-side mount points and even following referrals to
filesystem volumes on other servers.

Since the standard VFS path lookup code already supports walking paths
that contain all these features (using in-kernel automounts for
following referrals) we would like to be able to reuse that rather than
duplicate the full path traversal functionality in the NFSv4 client code.

This patch therefore defines a VFS helper function create_mnt_ns(), that
sets up a temporary filesystem namespace and attaches a root filesystem to
it. It exports the create_mnt_ns() and put_mnt_ns() function for use by
filesystem modules.

[ARM] idle: clean up pm_idle calling, obey hlt_counter

pm_idle is used by infrastructure (eg, cpuidle) which expects architectures
to call it in a certain way.  Arrange for ARM to follow x86's lead on this
and call pm_idle() with interrupts already disabled.  However, we expect
pm_idle() to enable interrupts before it returns.

Also, OMAP wants to be able to disable hlt-ing, so allow hlt_counter to
prevent all calls to pm_idle.

bfin_jtag_comm: clean up printk usage

The original patch garned some feedback and a v2 was posted, but that
version seems to have been missed when merging the driver.

At any rate, this cleans up the printk usage as suggested by Jiri Slaby.

15 years agoparport_pc: set properly the dma_mask for parport_pc device

parport_pc: set properly the dma_mask for parport_pc device

parport_pc_probe_port() creates the own 'parport_pc' device if the
device argument is NULL. Then parport_pc_probe_port() doesn't
initialize the dma_mask and coherent_dma_mask of the device and calls
dma_alloc_coherent with it. dma_alloc_coherent fails because
dma_alloc_coherent() doesn't accept the uninitialized dma_mask:

http://lkml.org/lkml/2009/6/16/150

Long ago, X86_32 and X86_64 had the own dma_alloc_coherent
implementations; X86_32 accepted a device having dma_mask that is not
initialized however X86_64 didn't. When we merged them, we chose to
prohibit a device having dma_mask that is not initialized. I think
that it's good to require drivers to set up dma_mask (and
coherent_dma_mask) properly if the drivers want DMA.

15 years agoparport_pc: after superio probing restore original register values

parport_pc: after superio probing restore original register values

CONFIG_PARPORT_PC_SUPERIO probes for various superio chips by writing
byte sequences to a set of different potential I/O ranges.  But the
probed ranges are not exclusive to parallel ports.  Some of our boards
just happen to have a watchdog in one of them.  Took us almost a week
to figure out why some distros reboot without warning after running
flawlessly for 3 hours.  For exactly 170 = 0xAA minutes, that is ...

Fixed by restoring original values after probing.  Also fixed too small
request_region() in detect_and_report_it87().
