This patch (as1231) fixes a use-after-free bug in g_file_storage. A
device's name may not be available after the device is unregistered,
even if the device structure itself is still allocated. Since
close_backing_file() prints a LUN's name for debugging, it shouldn't
be called after the LUN has been unregistered.
That whole area needed to be cleaned up; the backing files were
getting closed in a couple of different places. The patch fixes
things so that they get closed in just one place, as part of the
unbind procedure, immediately before the LUN is unregistered.

Without this patch, the driver won't check that the last fully-occupied
uframe for a new split transaction was vacant beforehand. This can
lead to a situation in which the first 188 bytes of a 192-byte
isochronous transfer are scheduled in the same uframe as an existing
interrupt transfer. The resulting schedule looks like this:
uframe 0: 188-byte isoc-OUT SSPLIT, 8-byte int-IN SSPLIT
uframe 1: 4-byte isoc-OUT SSPLIT
The SSPLITs are intermingled, causing an error in the downstream hub's
TT.
If you are having problems with devices or hub ports resetting, or failed
interrupt transfers, when you start using a USB audio or video (Isochronous)
device, this patch may help.

This patch (as1229) fixes a few lifetime and locking problems in the
usb-serial driver. The main symptom is that an invalid kevent is
created when the serial device is unplugged while a connection is
active.
Ports should be unregistered when device is disconnected,
not when the parent usb_serial structure is deallocated.
Each open file should hold a reference to the corresponding
port structure, and the reference should be released when
the file is closed.
serial->disc_mutex should be acquired in serial_open(), to
resolve the classic race between open and disconnect.
serial_close() doesn't need to hold both serial->disc_mutex
and port->mutex at the same time.
Release the subdriver's module reference only after releasing
all the other references, in case one of the release routines
needs to invoke some code in the subdriver module.
Replace a call to flush_scheduled_work() (which is prone to
deadlocks) with cancel_work_sync(). Also, add a call to
cancel_work_sync() in the disconnect routine.
Reduce the scope of serial->disc_mutex in serial_disconnect().
The only place it really needs to protect is where the
"disconnected" flag is set.
This fixes the bug reported in

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.

Linux-2.6.29 deleted the legacy ACPI idle handler, leaving
the CPU_IDLE handler, which does not track bus master activity.
So delete the unused bm_activity field -- it is confusing to
print an always zero value.
This patch could break programs that parse
/proc/acpi/processor/*/power, since it deletes this
line from that file:
bus master activity: 00000000

The c2 and c3 idle handlers check tsc_halts_in_c()
after every time they return from idle. Um, when?:-)
Move this check to init-time to remove the unnecessary
run-time overhead, and also to have the check complete before
the first entry into the idle handler.
ff69f2bba67bd45514923aaedbf40fe351787c59
(acpi: fix of pmtimer overflow that make Cx states time incorrect)
replaced the hard-coded use of the PM-timer inside idle,
with ktime_get_readl(), which possibly uses the TSC --
so it is now especially prudent to detect a broken TSC
before entering idle.

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

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.

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.

* 'i2c-for-linus' of git://jdelvare.pck.nerim.net/jdelvare-2.6:
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.

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.

declared on the stack and thus the &pCfg->timer is always on the stack I
changed init_timer() to init_timer_on_stack() and it seems to have shut
up.....

For an upcoming distro release, we need to have the xp kernel module
loadable even when not on UV equipment. The xpc module will not load.
This will allow one set of modules dependent upon xp to work on either UV
or non-UV equipment.

With no IRQ available/defined, RTC-CMOS driver prints something like:
rtc0: alarms up to one no, y3k, 114 bytes nvram
^^^^
I guess the following is a bit easier to understand:
rtc0: no alarms, y3k, 114 bytes nvram

On line 944 the return value of flush() is considered as a boolean,
but limit reaches -1 upon timeout which evaluates to true.
On 540, 594, 720 the same occurs for wait_ssp_rx_stall()
On 536 the same occurs for wait_dma_channel_stop()

If DMA is enabled, any spi_sync call after suspend/resume would block
forever, because DRCMR is lost on suspend. This patch restores DRCMR to
the same values set by probe.

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.

Bela Lubkin noticed that the statistics for send IPMB and LAN commands
in the IPMI driver could be incremented even if an error occurred. Move
the increments to the proper place to avoid this.
Also add some statistics for retransmissions that failed, and some little
helper functions to neaten up the code a little.

The IPMI driver would attempt to use the event buffer even if that
didn't exist on the BMC. This patch modified the IPMI driver to check
for the event buffer's existence before trying to use it.

Move the go7007 driver away from the legacy i2c binding model, which
is going away really soon now.
The I2C addresses of the audio and video chips in s2250-board didn't
look quite right, apparently they were left-aligned values when Linux
wants right-aligned values, so I fixed them too.
