The driver takes into account not only the interrupt status bit but
also "FIFO empty" bit in its test_irq() method. This actually is a
superfluous check since for the DMA commands calling the
dma_test_irq() method further in the interrupt handler makes sure FIFO
is emptied.

Port autoselection done by kernel only works when number of bound
sockets is under a threshold (typically 30000).
When this threshold is over, we must check if there is a conflict before
exiting first loop in inet_csk_get_port()
Change inet_csk_bind_conflict() to forbid two reuse-enabled sockets to
bind on same (address,port) tuple (with a non ANY address)
Same change for inet6_csk_bind_conflict()

According to libata-core correctly around line 6572:
/* parse id */
p = strchr(id, '.');
...
the optional device is separated from the port in the libata.force ID
by a point or dot instead of by a colon.
Fix documentation to reflect this.

This adds support for Memory24, Memory32, and Memory32Fixed descriptors in
PCI host bridge _CRS.
I experimentally determined that Windows (2008 R2) accepts these descriptors
and treats them as windows that are forwarded to the PCI bus, e.g., if
it finds any PCI devices with BARs outside the windows, it moves them into
the windows.
I don't know whether any machines actually use these descriptors in PCI
host bridge _CRS methods, but if any exist and they're new enough that we
automatically turn on "pci=use_crs", they will work with Windows but not
with Linux.

Add an SKF_AD_HATYPE field to the packet ancilliary data area, giving
access to skb->dev->type, as reported in the sll_hatype field.
When capturing packets on a PF_PACKET/SOCK_RAW socket bound to all
interfaces, there doesn't appear to be a way for the filter program to
actually find out the underlying hardware type the packet was captured
on. This patch adds such ability.
This patch also handles the case where skb->dev can be NULL, such as on
netlink sockets.

Redirecting directly to lsm, here's the patch discussed on lkml:
http://lkml.org/lkml/2010/4/22/219
The mmap_min_addr value is useful information for an admin to see without
being root ("is my system vulnerable to kernel NULL pointer attacks?") and
its setting is trivially easy for an attacker to determine by calling
mmap() in PAGE_SIZE increments starting at 0, so trying to keep it private
has no value.
Only require CAP_SYS_RAWIO if changing the value, not reading it.
