Currently the driver tries to save context in the suspend path, but
will cause an abort if the device is already runtime suspended. This
happens, for example, if MUSB loaded/compiled-in, in host mode, but no
USB devices are attached. MUSB will be runtime suspended, but then
attempting a system suspend will crash due to the context save
being attempted while the device is disabled.
On OMAP, as of v3.1, the driver's ->runtime_suspend() callback will be
called late in the suspend path (by the PM domain layer) if the driver
is not already runtime suspended, ensuring a full shutdown.
Therefore, the context save is not needed in the ->suspend() method
since it will be called in the ->runtime_suspend() method anyways
(similarily for resume.)
NOTE: this leaves the suspend/resume methods basically empty (with
some FIXMEs and comments, but I'll leave it to the maintainers
to decide whether to remove them.

This quirk sould be reverted. It has the following probems:
1) The quirk was intended to "ASUS MV2-MX SE" motherboards only, but the
ID used matches a much broader range, potentially all boards containing a
VIA chipset model in the family of vendor VIA 0x1106 and audio device ID
0x3288, which encompasses VIA-VT82xx, VIA-VT1xx and VIA-VT20xx chipsets.
2) VIA chipsets rely on azx_via_get_position() to handle correctly dma
transfers during capture. Using POS_FIX_LPIB instead of POS_FIX_VIACOMBO
leads to partially corrupted input buffers during capture. The effects
of this bug are not immediately visible, it took strong DSP expertise,
some expensive signal generator and a spectrum analyzer to identify it
and verify correct behaviour using original default.
3) It's almost certain that the quirk did not fix the real problem,
if there was one. Refer to original submission:

Since 2005 (c1b4a7e695)
tcp_tso_should_defer has been using tcp_max_burst() as a target limit
for deciding how large to make outgoing TSO packets when not using
sysctl_tcp_tso_win_divisor. But since 2008
(dd9e0dda66) tcp_max_burst() returns the
reordering degree. We should not have tcp_tso_should_defer attempt to
build larger segments just because there is more reordering. This
commit splits the notion of deferral size used in TSO from the notion
of burst size used in cwnd moderation, and returns the TSO deferral
limit to its original value.

struct nr_route_struct's mnemonic permits a string of up to 7 bytes to be
used. If userland passes a not zero terminated string to the kernel adding
a node to the routing table might result in the kernel attempting to read
copy a too long string.
Mnemonic is part of the NET/ROM routing protocol; NET/ROM routing table
updates only broadcast 6 bytes. The 7th byte in the mnemonic array exists
only as a \0 termination character for the kernel code's convenience.
Fixed by rejecting mnemonic strings that have no terminating \0 in the first
7 characters. Do this test only NETROM_NODE to avoid breaking NETROM_NEIGH
where userland might passing an uninitialized mnemonic field.

To allow the use of AX.25 for even the most extreme setup (think packet

Tg3 normally gets a performance boost by increasing the PCI Maximum Read
Request Size (MRRS) to 4k. Unfortunately, this is causing some problems
on particular hardware platforms. This patch removes all code that
modifies the MRRS except for one case.
As part of a solution to fix an internal FIFO problem on the 5719, the
driver artificially capped the MRRS to 2k for the entire 5719, and later
5720, ASIC revs. This was overly aggressive and only really needed to
be done for the 5719 A0. In the spirit of the rest of this patch, the
driver will only reprogram the MRRS for this device if the value exceeds
the 2k cap.

On the earliest TSO capable devices, TSO was accomplished through
firmware. The TSO cannot coexist with ASF management firmware though.
The tg3 driver determines whether or not ASF is enabled by calling
tg3_get_eeprom_hw_cfg(), which checks a particular bit of NIC memory.
Commit dabc5c670d, entitled "tg3: Move
TSO_CAPABLE assignment", accidentally moved the code that determines
TSO capabilities earlier than the call to tg3_get_eeprom_hw_cfg(). As a
consequence, the driver was attempting to determine TSO capabilities
before it had all the data it needed to make the decision.
This patch fixes the problem by revisiting and reevaluating the decision
after tg3_get_eeprom_hw_cfg() is called.
