When requesting all prl entries (kprl.addr == INADDR_ANY) and there are
more prl entries than there is space passed from userspace, the existing
code would always copy cmax+1 entries, which is more than can be handled.
This patch makes the kernel copy only exactly cmax entries.

Commit 2b85a34e91
(net: No more expensive sock_hold()/sock_put() on each tx)
opens a window in sock_wfree() where another cpu
might free the socket we are working on.
A fix is to call sk->sk_write_space(sk) while still
holding a reference on sk.

The move away from having drivers assign wireless handlers,
in favour of making cfg80211 assign them, broke the sysfs
registration (the wireless/ dir went missing) because the
handlers are now assigned only after registration, which is
too late.
Fix this by special-casing cfg80211-based devices, all
of which are required to have an ieee80211_ptr, in the
sysfs code, and also using get_wireless_stats() to have
the same values reported as in procfs.

Multiple problems were reported due to interaction
between wpa_supplicant and the wext compat code in
cfg80211, which appear to be due to it not getting
any bss pointer here when wpa_supplicant sets all

bss after doing an extra scan, but that appears to
increase the time we need for connecting enough to

When hardware or uCode problem occurs driver captures significant
information from device to enable debugging. The format of this information
is different between 3945 and 4965 and later devices, yet currently the
3945 uses the 4965 and later format. Fix this by adding a new library call
that is initialized to the correct formatting routine based on device.
This moves the iwlagn event and error log handling back to iwl-agn.c to
make it part of iwlagn module.
Also remove the 3945 sysfs file that triggers dump of event log - there is
already a debugfs file that can do it for all drivers.

We keep track of where to write into a buffer by keeping a count of how
much has been written so far. When writing to the buffer we thus take the
buffer pointer and adding the count of what has been written so far.
Keeping track of what has been written so far is done by incrementing
this number every time something is written to the buffer with how much has
been written at that time.
Currently this number is incremented incorrectly when using the
"hex_dump_to_buffer" call to add data to the buffer. Fix this by only
adding what has been added to the buffer in that call instead of what has
been added since beginning of buffer.

The sys_socketcall() function has a very clever system for the copy

This is because the driver manages interrupts without checking for
netif_running().
Though, there are few other issues with suspend/resume in this driver.
The intention of calling free_irq() in suspend() was to avoid any
possible spurious interrupts (see commit 5b039e681b
"3c59x PM fixes"). But,
- On resume, the driver was requesting IRQ just after pci_set_master(),
but before vortex_up() (which actually resets 3c59x chips).
- Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy
HW won't trigger spurious interrupts in another driver that
requested the same interrupt. So, if we want to protect from
unexpected interrupts, then on suspend we should issue disable_irq(),
not free_irq().

recursion prevention is done at the upper level (in dev_queue_xmit()),

If we ever implement this, then we can stop returning an error.

Allocating a port number to a socket and hashing that socket shall be
an atomic operation with regards to other port allocation. Otherwise,
we could allocate a port that is already being allocated to another
socket.

Previous update did not resched in inner loop causing watchdogs.
Rewrite inner loop to:
* account for delays better with less clock calls
* more accurate timing of delay:
- only delay if packet was successfully sent
- if delay is 100ns and it takes 10ns to build packet then
account for that
* use wait_event_interruptible_timeout rather than open coding it.
