Update the in-kernel hotplug example script to work
properly with recent kernels. Without this fix the
script may load the firmware twice - both at "add"
and "remove" time.
The second load only triggers in the case when multiple
firmware images are used. A good example is the b43
driver which does not work properly without this fix.

There is little rationale for marking bus_for_each_drv() __must_check.
It is more of an iteration helper than a real function. You don't know
in advance which callback it will be used on, so you have no clue how
important it can be to check the returned value. In practice, this
helper function can be used for best-effort tasks.
As a matter of fact, bus_for_each_dev() is not marked __must_check.
So remove it from bus_for_each_drv() as well. This is the same that
was done back in October 2006 by Russell King for
device_for_each_child(), for exactly the same reasons.

The kernel/hotplug sysctl variable (/proc/sys/kernel/hotplug file) was
made conditional on CONFIG_NET by commit
f743ca5e10f4145e0b3e6d11b9b46171e16af7ce (applied in 2.6.18) to fix
problems with undefined references in 2.6.16 when CONFIG_HOTPLUG=y &&
!CONFIG_NET, but this restriction is no longer needed.
This patch makes the kernel/hotplug sysctl variable depend only on
CONFIG_HOTPLUG.

If the bitmap block on disk is bad, ext4_mb_load_buddy() returns an
error. This error is returned to the caller,
ext4_mb_regular_allocator() and then to ext4_mb_new_blocks(). But
ext4_mb_new_blocks() did not check for the return value of
ext4_mb_regular_allocator() and would repeatedly try to load the
bitmap block. The fix simply catches the return value and exits out of
the 'repeat' loop after cleanup.
We also take the opportunity to clean up the error handling in
ext4_mb_new_blocks().

The main motivation of this patch changing strcpy() to strlcpy().
We strcpy() to copy a 48 byte buffers into a 49 byte buffers. So at
best the last byte has leaked information, or maybe there is an
overflow? Anyway, this patch closes the information leaks by zeroing
the memory and the calls to strlcpy() prevent overflows.

I'm trying to generate a <set> of <book>s in docbook for wireless to

However, docbook will generate "re01.html" anew for each book for the

An effective workaround is to use IDs for the filenames, which makes
them more descriptive as well, e.g. API-enum-ieee80211-band.html.

Fix this leftover TODO from the cfg80211 conversion by doing a scan
if cfg80211 didn't pass in the BSSID for us. Since the scan code
uses so much of the cfg80211_scan_request structure to build up the
firmware command, we just fake one when the scan request is triggered
internally. But we need to make sure that internal 'fake' cfg82011
scan request does not get back to cfg82011 via cfg80211_scan_done().

In data=journal mode, we still use block_write_begin() to prepare page for
writing. This function can occasionally mark buffer dirty which violates
journalling assumptions - when a buffer is part of a transaction, it should be
dirty and a buffer can be already part of a forget list of some transaction
when block_write_begin() gets called. This violation of journalling assumptions
then results in "JBD: Spotted dirty metadata buffer..." warnings.
In fact, temporary dirtying the buffer while the page is still locked does not
really cause problems to the journalling because we won't write the buffer
until the page gets unlocked. So we just have to make sure to clear dirty bits
before unlocking the page.

Add DNS query support for AFS so that it can get the IP addresses of Volume

description.

Separate out the DNS resolver key type from the CIFS filesystem into its own
module so that it can be made available for general use, including the AFS
filesystem module.
This facility makes it possible for the kernel to upcall to userspace to have
it issue DNS requests, package up the replies and present them to the kernel
in a useful form. The kernel is then able to cache the DNS replies as keys
can be retained in keyrings.
Resolver keys are of type "dns_resolver" and have a case-insensitive
description that is of the form "[<type>:]<domain_name>". The optional <type>
indicates the particular DNS lookup and packaging that's required. The
<domain_name> is the query to be made.
If <type> isn't given, a basic hostname to IP address lookup is made, and the
result is stored in the key in the form of a printable string consisting of a
comma-separated list of IPv4 and IPv6 addresses.
This key type is supported by userspace helpers driven from /sbin/request-key
and configured through /etc/request-key.conf. The cifs.upcall utility is
invoked for UNC path server name to IP address resolution.
The CIFS functionality is encapsulated by the dns_resolve_unc_to_ip() function,
which is used to resolve a UNC path to an IP address for CIFS filesystem. This
part remains in the CIFS module for now.
See the added Documentation/networking/dns_resolver.txt for more information.

It turns out that not all directory inodes with dentries on the
i_dentry list are unusable here. We only consider them unusable if they
are still hashed or if they have a root dentry attached.
Full disclosure -- this check is inherently racy. There's nothing that
stops someone from slapping a new dentry onto this inode just after
this check, or hashing an existing one that's already attached. So,
this is really a "best effort" thing to work around misbehaving servers.

In denali driver, wTotalBlocks variable is useless, so just
remove them in get_toshiba_nand_para and get_hynix_nand_para
first. Other wTotalBlocks in denali.c and other variables in
dev_info struct are also useless, will remove them later.
Also add a parameter in get_hynix_nand_para to prepare to
remove dev_info struct. This parameter comes by reading NAND
ID directly. Reading register will report wrong value for
some NAND chips, e.g. some Micron MT29F32G08QAA chips.
So update NAND_CMD_READID method as well.

Current EDMA driver is not taking care of EDMA channels/slots
which are allocated from other processor, say DSP. If a
channel/slot is allocated from DSP, the existing EDMA driver
can still allocate the same resource on ARM.
This patch enables the user to pass the channel/slots reserved
for DSP as platform data. EDMA driver scans this list during
probe and prepares a bitmap of channel/slots which can be used
on ARM side.
Trying to reserve channels by doing a 'pre-allocate' using
edma_alloc_{slot|channel}() API does not work because
1) The reservation should be done in probe() to avoid race
with other ARM side driver trying to use EDMA
2) The alloc channel API sets up the access through shadow region
0 which will be incorrect for DSP usage. It also sets up the
channel <-> queue number mapping which is not required as DSP
will likely do its own mapping anyway.
3) (minor) There is no API to allocate channels in bulk.
