fd2f3bddae ieee1394: replace vmalloc by kmalloc in csr1212
The biggest chunk ever allocated by CSR1212_MALLOC is 1024 Bytes +
sizeof(struct csr1212_csr_rom_cache) big.  Most of the time much
smaller data structures are allocated.  Therefore vmalloc is a waste.

The one exception is csr1212_append_new_cache() which is called to
append a chunk of CSR1212_EXTENDED_ROM_SIZE + sizeof(struct
csr1212_csr_rom_cache) if the currently allocated ROM cache is too
small.  CSR1212_EXTENDED_ROM_SIZE is generously defined as 256 kBytes.
In SVN commit 1220, Steve Kinneberg lowered this to 2 kBytes in the
config_rom_2.4 branch.  This same commit also switched CSR1212_MALLOC
from kmalloc to vmalloc in the SVN trunk branch:

(It was actually 2 kB, not 8 kB.)

I am now setting CSR1212_EXTENDED_ROM_SIZE to 2 kB minus the overhead of
struct csr1212_csr_rom_cache.  Note, this code path is not used by the
in-kernel drivers though.  raw1394 could trigger it, but the respective
libraw1394 functions don't exist yet.

Furthermore, userspace programs can replace the entire local ROM via
raw1394.  If kmalloc does not fulfill their needs --- well, tough luck.
I decree that nobody needs such huge extended ROMs.  (Extended ROMs are
defined by IEEE 1212 clause 7.7.18.  The spec does not impose
practically relevant restrictions on the size of extended ROM chunks.)

Another potentially demanding use of CSR1212_MALLOC is if external
FireWire devices come with Extended ROM entries.  If they are too big
for kmalloc (or have been too big for vmalloc) we just fail to read
their ROM.  This is quite unlikely though, to my knowledge.

7fb9addba8 ieee1394: drop csr1212's support for external compilation
csr1212 was written to be compiled either as part of the ieee1394 kernel
driver or of an anticipated IEEE 1212 userspace library.  We now drop
support for the latter.  The costs in terms of code footprint and depth
of abstraction are not countered by any actual benefit.

Also remove some obsolete #includes.

2446a79f4f ieee1394: sbp2: optimize DMA direction of s/g tables
Unlike the name suggests, "cmd->scatter_gather_element" holds only the
s/g table, not the actual s/g elements.  Since the table is only read
but never written by the device, DMA_BIDIRECTIONAL can be replaced by
DMA_TO_DEVICE which may be cheaper on some architectures.

f412bf440b ieee1394: sbp2: remove unnecessary alignments of struct members
The members "dma_addr_t command_orb_dma" and "dma_addr_t sge_dma" of
sbp2.h::sbp2_command_info do not have to be aligned themselves --- only
the memory which they point to has to be.

The member "struct sbp2_command_orb command_orb" has to be aligned on
4 bytes boundary which is guaranteed because it contains u32 members.

The member "struct sbp2_unrestricted_page_table scatter_gather_element",
i.e. the SBP-2 s/g table, has to be aligned on 8 bytes boundary
according to the SBP-2 spec.  This is not a requirement for FireWire
controllers but could be expected by SBP-2 targets.

I see no need to align the members command_orb and
scatter_gather_element on CPU cacheline boundaries.  It could have
performance benefits, but on the other hand sbp2 has a somewhat wasteful
allocation scheme which should be optimized first before further tweaks
like cacheline alignments.  (E.g. don't always allocate SG_ALL s/g table
elements.)

Note, before as well as after the patch, the code relies on the
assumption that memory alignment in the virtual address space is
preserved in the physical address space after DMA mapping.

dc5a144991 sis900: Allocate rx replacement buffer before rx operation
Just found a hole in my last patch.  It was reported to me that shortly after we
integrated this patch.  The report was of an oops that took place inside of
netif_rx when using the sis900 driver.  Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame.  The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring.  So if you receive frames fast enough the skb being processed by
the network stack can get corrupted.  The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP.  I'll post test results when I hear
them, but I think this is a pretty straightforward fix.  It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.

147c5a1733 USB: iowarrior.c: timeouts too small in usb_control_msg calls
The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.

The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.

The patch also removes a useless debug statement, which was left over
from testing a broken firmware version

1b101ceb91 USB: remove ancient/broken CRIS hcd
Remove the old crisv10 HCD ... it can't have built for some time,
doesn't even have a Kconfig entry, was the last driver not to have
been converted to the "hcd" framework, and considering the usbcore
changes since its last patch was merged, has just got to buggy as
all get-out.

I'm told Axis has a new driver, and will be submitting it soon.

b8d297c93a usb ethernet gadget, workaround network stack API glitch
Another workaround for the glitch in the network layer, whereby one call
ignores the (otherwise kernel-wide) convention that free() calls should
not oops when passed nulls.  This code already handles that API glitch in
most other paths.

6a02c996bc USB: cxacru: ADSL state management
The device has commands to start/stop the ADSL function, so this adds a
sysfs attribute to allow it to be started/stopped/restarted.  It also stops
polling the device for status when the ADSL function is disabled.

There are no problems with sending multiple start or stop commands, even
with a fast loop of them the device still works.  There is no need to
protect the restart process from further user actions while it's waiting
for 1.5s.

7d5e1dd40b usbatm: Detect usb device shutdown and ignore failed urbs
Detect usb device shutdown and ignore failed urbs.  This happens when the
driver is unloaded or the device is unplugged.

I'm not sure what other urb statuses should be ignored, and the warning
message doesn't need to be shown when the module is unloaded or the device
is removed.
