[PATCH 18/25] powerpc,kgdb: Introduce low level trap catching
The only way the debugger can handle a trap in inside rcu_lock, notify_die, or atomic_notifier_call_chain without a recursive fault is to allow the kernel debugger to handle the exception first in program_check_exception(). The other change here is to make sure that kgdb_handle_exception() is called with correct... 18 May 2010 22:31

[PATCH 6/7] earlyprintk,vga,kdb: Fix \b and \r for earlyprintk=vga with kdb
Allow kdb to work properly with with earlyprintk=vga by interpreting the backspace and carriage return output characters. These interpretation of these characters is used for simple line editing provided in the kdb shell. CC: Thomas Gleixner <tglx(a)linutronix.de> CC: Ingo Molnar <mingo(a)redhat.com> CC: H.

[PATCH 0/4] Enable cpu frequency and power tracking for cpuacct cgroup
Rebased onto linux-next. This patch series introduces cpu frequency and power tracking for cpuacct cgroups. A similar patch set was discussed a while back and it was concluded that due to varying architectures (ppc, x86 with overboot) you cannot account for frequencies and their power consumption generically in ... 18 May 2010 22:31

Does anyone care about gcc 3.x support for *x86* anymore?
[Reposting as a separate thread] Recently, we have seen an increasing number of problems with gcc 3.4 on x86; mostly due to poor constant propagation producing not just bad code but failing to properly eliminate what should be dead code. I'm wondering if there is any remaining real use of gcc 3.4 on x86 for co... 20 May 2010 16:07

Yes, it basically says "don't make this handler threaded". That is a good fix for EHEA, but the threaded handling is still ... 20 May 2010 18:18

mm: remove all rcu head initializations
Hi Hello! Would you guys like to carry this patch, or should I push it up -tip? If I don't hear otherwise from you, I will push it up -tip. The INIT_RCU_HEAD() primitive is going away in favor of debugobjects. Thanx, Paul Personally, I don't think this patch can make major conflict. ... 18 May 2010 22:31
