crtools uses a parasite code for dumping processes. The parasite code is
injected into a process with help PTRACE_SEIZE.
Currently crtools blocks signals from a parasite code. If a process has
pending signals, crtools wait while a process handles these signals.
This method is not suitable for stopped tasks. A stopped task can have a
few pending signals, when we will try to execute a parasite code, we will
need to drop SIGSTOP, but all other signals must remain pending, because a
state of processes must not be changed during checkpointing.
This patch adds two ptrace commands to set/get signal-blocked mask.
I think gdb can use this commands too.

Yet one more pull request for wireless updates intended for 3.11...
For the mac80211 bits, Johannes says:
"Here we have a few memory leak fixes related to BSS struct handling
mostly from Ben, including a fix for a more theoretical problem
(associating while a BSS struct times out) from myself, a compilation
warning fix from Arend, mesh fixes from Thomas, tracking the beacon
bitrate (Alex), a bandwidth change event fix (Ilan) and some initial
work for 5/10 MHz channels from Simon."
Regarding the iwlwifi bits, Johannes says:
"Emmanuel removed some unneeded/unsupported module parameters and adds a
Bluetooth 1x1 lookup-table for some upcoming products. From Alex I have
an older patch to add low-power receive support, this depended on a
mac80211 commit that only just came in with the merge from wireless-next
I did. Ilan made beacon timings better, and Eytan added some debug
statements for thermal throttling. I have a few cleanups, a fix for a
long-standing but rare warning, and, arguably the most important patch
here, the firmware API version bump for the 7260/3160 devices."
Also included is a Bluetooth pull -- Gustavo says:
"Here goes a set of patches to 3.11. The biggest work here is from Andre Guedes
on the move of the Discovery to use the new request framework. Other than that
Johan provided a bunch of fixes to the L2CAP code. The rest are just small
fixes and clean ups."
On top of all that, there are a variety of updates and fixes to
brcmfmac, rt2x00, wil6210, ath9k, ath10k, and a few others here and
there. This also includes a pull of the wireless tree, in order to
prevent some merge conflicts.

The common case is that TCP/IP checksums have already been
verified, e.g. by hardware (rx checksum offload), or conntrack.
Userspace can use this flag to determine when the checksum
has not been validated yet.
If the flag is set, this doesn't necessarily mean that the packet has
an invalid checksum, e.g. if NIC doesn't support rx checksum.
Userspace that sucessfully enabled NFQA_CFG_F_GSO queue feature flag can
infer that IP/TCP checksum has already been validated if either the
SKB_INFO attribute is not present or the NFQA_SKB_CSUM_NOTVERIFIED
flag is unset.

So it looks like for virtual hw cursors on QXL we need to inform
the "hw" device what the cursor hotspot parameters are. This
makes sense if you think the host has to draw the cursor and interpret
clicks from it. However the current modesetting interface doesn't support
passing the hotspot information from userspace.
This implements a new cursor ioctl, that takes the hotspot info as well,
userspace can try calling the new interface and if it gets -ENOSYS it means
its on an older kernel and can just fallback.
