drm: add separate drm debugging levels
Now all the DRM debug info will be reported if the boot option of
"drm.debug=1" is added. Sometimes it is inconvenient to get the debug
info in KMS mode. We will get too much unrelated info.
This will separate several DRM debug levels and the debug level can be used
to print the different debug info. And the debug level is controlled by the
module parameter of drm.debug
In this patch it is divided into four debug levels;
drm_core, drm_driver, drm_kms, drm_mode.
At the same time we can get the different debug info by changing the debug
level. This can be done by adding the module parameter. Of course it can
be changed through the /sys/module/drm/parameters/debug after the system is
booted.
Four debug macro definitions are provided.
DRM_DEBUG(fmt, args...)
DRM_DEBUG_DRIVER(prefix, fmt, args...)
DRM_DEBUG_KMS(prefix, fmt, args...)
DRM_DEBUG_MODE(prefix, fmt, args...)
When the boot option of "drm.debug=4" is added, it will print the debug info
using DRM_DEBUG_KMS macro definition.
When the boot option of "drm.debug=6" is added, it will print the debug info
using DRM_DEBUG_KMS/DRM_DEBUG_DRIVER.
Sometimes we expect to print the value of an array.
For example: SDVO command,
In such case the following four DRM debug macro definitions are added:
DRM_LOG(fmt, args...)
DRM_LOG_DRIVER(fmt, args...)
DRM_LOG_KMS(fmt, args...)
DRM_LOG_MODE(fmt, args...)

drm/i915: Change GEM throttling to be 20ms like the comment says.
keithp didn't like the original 20ms plan because a cooperative client could
be starved by an uncooperative client. There may even have been problems
with cooperative clients versus cooperative clients. So keithp changed
throttle to just wait for the second to last seqno emitted by that client.
It worked well, until we started getting more round-trips to the server
due to DRI2 -- the server throttles in BlockHandler, and so if you did more
than one round trip after finishing your frame, you'd end up unintentionally
syncing to the swap.
Fix this by keeping track of the client's requests, so the client can wait
when it has an outstanding request over 20ms old. This should have
non-starving behavior, good behavior in the presence of restarts, and less
waiting. Improves high-settings openarena performance on my GM45 by 50%.

net_cls: fix unconfigured struct tcf_proto keeps chaining and avoid kernel panic when we use cls_cgroup
This patch fixes a bug which unconfigured struct tcf_proto keeps
chaining in tc_ctl_tfilter(), and avoids kernel panic in
cls_cgroup_classify() when we use cls_cgroup.
When we execute 'tc filter add', tcf_proto is allocated, initialized
by classifier's init(), and chained. After it's chained,
tc_ctl_tfilter() calls classifier's change(). When classifier's
change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto.
In addition, cls_cgroup is initialized in change() not in init(). It
accesses unconfigured struct tcf_proto which is chained before
change(), then hits Oops.

e1000: add missing length check to e1000 receive routine
Patch to fix bad length checking in e1000. E1000 by default does two
things:
1) Spans rx descriptors for packets that don't fit into 1 skb on recieve
2) Strips the crc from a frame by subtracting 4 bytes from the length prior to
doing an skb_put
Since the e1000 driver isn't written to support receiving packets that span
multiple rx buffers, it checks the End of Packet bit of every frame, and
discards it if its not set. This places us in a situation where, if we have a
spanning packet, the first part is discarded, but the second part is not (since
it is the end of packet, and it passes the EOP bit test). If the second part of
the frame is small (4 bytes or less), we subtract 4 from it to remove its crc,
underflow the length, and wind up in skb_over_panic, when we try to skb_put a
huge number of bytes into the skb. This amounts to a remote DOS attack through
careful selection of frame size in relation to interface MTU. The fix for this
is already in the e1000e driver, as well as the e1000 sourceforge driver, but no
one ever pushed it to e1000. This is lifted straight from e1000e, and prevents
small frames from causing the underflow described above

The phy power state persists across reboots; Windows, some BIOSes, and

users to remove all power to get the interface working (see
http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy

ACPI: sanity check _PSS frequency to prevent cpufreq crash
When BIOS SETUP is changed to disable EIST, some BIOS
hand the OS an un-initialized _PSS:
Name (_PSS, Package (0x06)
{
Package (0x06)
{
0x80000000, // frequency [MHz]
0x80000000, // power [mW]
0x80000000, // latency [us]
0x80000000, // BM latency [us]
0x80000000, // control
0x80000000 // status
},
...
These are outrageous values for frequency,
power and latency, raising the question where to draw
the line between legal and illegal. We tend to survive
garbage in the power and latency fields, but we can BUG_ON
when garbage is in the frequency field.
Cpufreq multiplies the frequency by 1000 and stores it in a u32 KHz.
So disregard a _PSS with a frequency so large
that it can't be represented by cpufreq.
