[Announce] Kernel RHEL6 testing 042stab062.22

[Kir Kolyshkin]

OpenVZ project has released an updated RHEL6 based
testing kernel. Read below for more information.

NOTE that this is a *testing* kernel, not recommended for production.


Changes
=======
Since 042stab62.1:
* [netfilter] iptables inability to handle > 2000 rules inside 32bit CT 
on 64bit node (PCLIN-31246)
* [cpuinfo] cpuflags are reported empty inside a CT on a node with 
single physical cpu. In particular this breaks yum (#2373)
* [cpt] fix raising kernel BUG() on cpt/rst of a ptraced task
* [cpt/delayfs] NFS remote locks handling has been fixed (PSBM-14815)
* [fairsched] a lot of scheduler enhancements mostly intended to improve 
performance on NUMA nodes, now tries to run CT processes on no more than 
vcpus configured for the CT (PSBM-14332)
* [framebuffer] Draw Parallels logo if node is booted in graphical mode 
and "psbm" kernel boot option is provided (PSBM-15257)
* [debug] added the ability to dump slab entries
* [mm debug] added an ability to catch double free in per-cpu page 
lists. Triggers BUG() if double free detected.
* [net] netlink messages handling code has been fixed (env context 
corrected). In particular this fixes network configuration using Network 
Manager (#2353, #2354)
* [fuse] trim 'count' of bytes to read to avoid reading beyond eof when 
racing with writeback (PSBM-15340)
* [fuse] one more race fixed in writeback (PSBM-15008)
* [cpt] ipv6 module detection error message has been improved
* [cpt] online migration failure between 2 nodes without ipv6 modules 
loaded/enabled has been fixed (PSBM-15431)
* [cpt] fixed tty struct leak (PSBM-15373)
* [mm] new sysctl has been introduced: vm.strict_mem_cpuset (=0 by 
default). If 0, mem cpuset will work as a hint, i.e. if allocation from 
allowed NUMA nodes fails, cpuset constraints will be ignored (PSBM-15613)
* [ploop] hang on fsync() on ro mount has been fixed (PSBM-15435)
* [fuse] a page-cache corruption has been eliminated
* [kstat] fixed a kernel panic due to cpu hard lockup caused by a 
deadlock in gathering statistics code (PCLIN-31259)
