This adds printk messages with basic information about the driver being loaded.
This information includes a summary of the compiled-in features, which
simplifies bug-reporting and debugging a lot.
Also a firmware ID is printed. This is a unique identifier blob for a specific
version of the firmware. This ID is attached to a specific version of the firmware
blob in b43-fwcutter (see fwcutter git).
This helps users to select the right firmware for their device.
This also makes it possible to use automated scripts to fetch and extract the right
firmware for the driver. (the script will grep the .ko for the "Firmware-ID: xxx" string.
While the driver might still support other versions of the firmware for backward
compatibility, this will always print out the officially supported version, which
people _should_ use.

This checks if the DMA address is bigger than what the controller can manage.
It will reallocate the buffers in the GFP_DMA zone in that case.

Value of count is used to decide when to replenish rx buffers. If it is
equal or above 8 we replenish the buffers. Ensure there is no starvation
by initializing count to 8 - thus forcing replenish at first iteration.
This is helpful when rx receives batches of buffers smaller than 8.

when setting up the tx descriptors for the hardware we must account for any
padding between the header and the data we might have added previously. frame
len is the length of the frame in the air (including FCS but no padding) and
buffer len is the length of the buffer (including padding, but without FCS).
changing the way ah_setup_tx_desc is called: now excluding the FCS, since it's
easier to add that in the function where we need it.
before this fix we sent trailing zero bytes after the packet (because frame len
included the padding) which was not a big problem without WEP, but with WEP
this resultes in a wrong WEP checksum and the packet is discarded - which is
how i noticed at all ;)
an easy way to run into header padding problems, btw, is to connect to a QoS
(WME) enabled access point (eg. madwifi) - QoS data frames are 2 byte longer
and will require padding.

When a directory inode is allocated in the last group and the last group
contains less than s_blocks_per_group blocks, the initial block allocated
for the directory is not always allocated in the same group as the
directory inode, but in one of the first groups of the filesystem (group 1
for example).
Depending on the current process's pid, ext4_find_near() and
ext4_ext_find_goal() can return a block number greater than the maximum
blocks count in the filesystem and in that case the block will be not
allocated in the same group as the inode.
The following patch fixes the problem.
Should the modification also be done in ext2/3 code?

With the flex_bg feature enabled, a large file creation oopses the
kernel. The BUG_ON is:
BUG_ON(len >= EXT4_BLOCKS_PER_GROUP(sb));
As the allocation of the bitmaps and the inode table can be done
outside the block group with flex_bg, this allows to allocate up to
EXT4_BLOCKS_PER_GROUP blocks in a group.

Two call sites used list_del() instead of list_del_init(). AFAIK the
