The umem driver issues two warnings on boot, due to blk_plug_device() and
blk_remove_plug() being called without q->queue_lock held. Starting with
e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions
warn if q->queue_lock doesn't appear to be locked. In fact, q->queue_lock
is NULL (though that apparently isn't otherwise a problem as the driver is
using card->lock for everything).
Although blk_init_queue() with take a request_fn_proc and spinlock_t*,
there isn't a corresponding init helper that takes a make_request_fn.
Setting queue_lock to &card->lock explicitly seems to work fine for me.
The warning goes away and the device appears to behave.

Bugfixes noted by checking the code against the controller
documentation (TI document number SPRUE21):
- Remove declarations for eight non-existent registers (!);
and remove accesses to two of them.
- Remove access to various non-existent bitfields in some of
the registers which *do* exist (those fields must-be-zero).
- Provide comment to replace bogus reset logic (removed above,
it relied on non-existent bitfields). Resets require GPIO
help; this driver doesn't currently know about that.
With some minor cleanup: relocate a comment, avoid an extra
lookup of the PIO timings.

mediabay shouldn't include <linux/ide.h> unconditionally so
remove the superfluous include from mediabay.c (<asm/mediabay.h>

This crash seems to happen due to an uninitialized variable "rc".
The compiler even warns about that:

After applying the trivial patch below, which just initializes
the variable to zero, the kernel doesn't crash any longer:

Fix UDMA throughput bug: tCYC averages t2CYCTYP/2, but the code
previously assumed it was the same as t2CYCTYP. (That is, it was
using just one clock edge, not both.) Move the table's type
declaration so it's adjacent to the table, making it more clear
what those numbers mean.
On one system this change increased throughput by almost 4x: UDMA/66
sometimes topped 23 MB/sec (on a drive known to do much better). On
another system it was around a 10% win (UDMA/66 up to 7+ MB/sec).
The difference might be caused by the ratio between memory and IDE
clocks. In the system with large speedup, this was exactly 2 (as a
workaround for a rev 1.1 silicon bug). The other system used a more
standard ratio of 1.63 (and rev 2.1 silicon) ... clock domain synch
might have some issues, they're not unheard-of.

While ifconfig eth0 up kernel calls open() of 8139 driver(8139too.c).
In rtl8139_hw_start() of rtl8139_open(), 8139 driver enable RX before
setting up the DMA buffer address. In this interval where RX was
enabled and DMA buffer address is not yet set up, any incoming
broadcast packet would be send to a strange physical address:
0x003e8800 which is the default value of DMA buffer address.
Unfortunately, this address is used by Linux kernel. So kernel panics.
This patch fix it by setting up DMA buffer address before RX enabled
and everything is fine even under broadcast packets attack.

Now that the powermac IDE host driver can be modular, we need to
export check_media_bay_by_base() and media_bay_set_ide_infos()
from drivers/macintosh/mediabay.c for it.
This fixes the following build error:

There is currently only one way for userspace to say "wait for my storage
device to get ready for the modules I just loaded": to load the
scsi_wait_scan module. Expectations of userspace are that once this
module is loaded, all the (storage) devices for which the drivers
were loaded before the module load are present.
Now, there are some issues with the implementation, and the async
stuff got caught in the middle of this: The existing code only
waits for the scsy async probing to finish, but it did not take
into account at all that probing might not have begun yet.
(Russell ran into this problem on his computer and the fix works for him)
This patch fixes this more thoroughly than the previous "fix", which
had some bad side effects (namely, for kernel code that wanted to wait for
the scsi scan it would also do an async sync, which would deadlock if you did
it from async context already.. there's a report about that on lkml):
The patch makes the module first wait for all device driver probes, and then it
will wait for the scsi parallel scan to finish.

go7007: Convert to the new i2c device binding model
|

A few issues wrt DMA were uncovered when using the driver with swiotlb.
- driver should not use memory after it has been mapped
- iwl3945's RX queue management cannot use all of iwlagn because
the size of the RX buffer is different. Revert back to using
iwl3945 specific routines that map/unmap memory.
- no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single,
we can just call pci_unmap_single initially
- only map the memory area that will be used by device. this is especially
relevant to the mapping of iwl_cmd. we should not map the entire
structure because the meta data at the beginning of structure contains
the address to be used later for unmapping. If the address to be used for
unmapping is stored in mapped data it creates a problem.
- ensure that _if_ memory needs to be modified after it is mapped that we
call _sync_single_for_cpu first, and then release it back to device with
_sync_single_for_device
- we mapped the wrong length of data for host commands, with mapped length
differing with length provided to device, fix that.
Thanks to Jason Andryuk <jandryuk@gmail.com> for significant bisecting

When debugging TX issues it is helpful to know the seq nr of the
frame being transmitted. The seq nr is printed as part of ucode's
log informing us which frame is being processed. Having this information
printed in driver log makes it easy to match activities between driver
and firmware.
Also make possible to print TX flags directly. These are already printed
as part of entire TX command, but having it printed directly in cpu format
makes it easier to look at.

This patch fixes a build warning in mwl8.c.
(Marvell TOPDOG wireless driver)
The warning it fixes is: "large integer implicitly truncated to unsigned type."
The rx_ctrl member of the mwl8k_rx_desc struct is 8 bit (__u8 ), whereas trying
to assign it a 32 bit value (which is returned from cpu_to_le32())
causes the compiler to issue
a truncation warning.

On parisc machines, which don't have HIL, removing the hp_sdc module
panics the kernel. Fix this by returning early in hp_sdc_exit() if no HP
SDC controller was found.
Add functionality to probe for the hp_sdc_mlc kernel module (which takes
care of the upper layer HIL functionality on parisc) after two seconds.
This is needed to get all the other HIL drivers (keyboard / mouse/ ..)
drivers automatically loaded by udev later as well.
