This patch (as1087d) fixes a long-standing problem in usbcore: Device,
interface, and endpoint attributes aren't added until _after_ the
creation uevent has already been broadcast.

Unfortunately there are a few attributes which cannot be created that
early.  The "descriptors" attribute is binary and so must be created
separately.  The power-management attributes can't be created until
the dev/power/ group exists.  And the interface string can vary from
one altsetting to another, so it has to be created dynamically.

The qla1280 driver was ANDing the output value of mailbox register
0 with (1 << target-number) to determine whether to enable queueing
on the target in question.

But mailbox register 0 has the status code for the mailbox command
(in this case, Set Target Parameters).  Potential values are:
/*
 * ISP mailbox command complete status codes
 */

So clearly that is in error.  I can't think what the author of that
line was looking for in a mailbox register, so I just eliminated the
AND.  flag is used later in the function, and I think that the later
usage was also wrong, though it was used to set values that aren't
used.  Oh well, an overhaul of this driver is not what I want to do
now -- just a bugfix.

After the fix, I found that my disks were getting a queue depth of
255, which is far too many.  Most SCSI disks are limited to 32 or
64.  In any case, there's no point, queueing up a bunch of commands
to the adapter that will just result in queue full or starve other
targets from being issued commands due to running out of internal
memory.  So I dropped default queue depth to 32 (from which 1 is
subtracted elsewhere, giving net of 31).

I tested with a Seagate ST336753LC, and results look good, so
I'm satisfied with this patch.

Some versions of X used the mprotect workaround to change caching type from UC
to WB, so that it can then use mtrr to program WC for that region [1].  Change
the mmap of pci space through /sys or /proc interfaces from UC to UC_MINUS.
With this change, X will not need to use mprotect workaround to get WC type
since the MTRR mapping type will be honored.

The bug in mprotect that clobbers PAT bits is fixed in a follow on patch. So,
this X workaround will stop working as well.

That patch is buggy. We had an implicit assumption that
dev = NULL for ISA devices that require 24bit DMA.

The recent work on x86 dma_alloc_coherent() breaks the ISA DMA buffer
allocation, which is represented by "dev = NULL" and requires 24bit
DMA implicitly.

Fix uninitialized variable in __pci_osc_support_set().

If the ACPI namespace doesn't have any device object corresponding to
the specified hid, 'retval' in __pci_osc_support_set() is not changed
by the acpi_query_osc() callback. Since 'retval' is not initizlized in
the current implementation, the contents of 'retval' is undefined in
this case. This causes a mis-handling of ctrlset_buf[OSC_SUPPORT_TYPE]
and will cause an unexpected result in the subsequent
pci_osc_control_set() call as a result.

fbcon still was not doing the right thing (read: continued to do old

the previous one only (where "foo" appears).  So just temporarily set the

nothing in the API to prevent it.  Unfortunately there's a known case in
NTFS-3G where big writes cause filesystem corruption.  There could also be
other filesystems, where the lack of testing with big write requests would

To prevent such problems on a kernel upgrade, disable big writes by default,

The current driver may cause glitches on SPI CLK line since one must disable
the SPI controller before changing any HW settings.  Fix this by implementing
a local spi_transfer function that won't change speed and/or word size while
CS is active.

While doing that heavy lifting a few other issues were addressed too:
 - Make word size 16 and 32 work too.
 - Honor bits_per_word and speed_hz in spi transaction.
 - Optimize the common path.

This also stops using the "bitbang" framework (except for a few constants).

The input argument to rtc_time_to_tm() is unsigned as well as are members of
the output structure.  However signed arithmetic is used within for
calculations leading to incorrect results for input values outside the signed
positive range.  If this happens the time of day returned is out of range.

Found the problem when fiddling with the RTC and the driver where year was set
to an unexpectedly large value like 2070, e.g.:

rtc0: setting system clock to 2070-01-01 1193046:71582832:26 UTC (3155760954)

while it should be:

rtc0: setting system clock to 2070-01-01 00:15:54 UTC (3155760954)

Changing types to unsigned fixes the problem.
