[PROPOSAL - FIRST POST] NMI & register clash handling infrastructure
Hi, This is my first post to the group, please excuse me, If I unknowingly miss to follow writing ethics. Proposal/Need: I was working on providing accurate process usage support, and writing a kernel module, I configured cpu-core-unhalted-event and configured LVT (local vector table) with NMI (non-maskab... 8 Jun 2010 05:50
[PATCH 0/5] ACPI / ACPICA: Fix problems related to GPE reference counting
Hi, I decided to split this big patch into a series of smaller ones addressing one issue each. I think all of the issues addressed by [2-5/5] may be regarded as regressions from 2.6.33, because that kernel didn't have these problems. [1/5] - Not really a fix, but [2/5] depends on it and I don't see a reason to... 8 Jun 2010 05:50
[PATCH 3/6] tracing, vmscan: Add trace event when a page is written
This patch adds a trace event for when page reclaim queues a page for IO and records whether it is synchronous or asynchronous. Excessive synchronous IO for a process can result in noticeable stalls during direct reclaim. Excessive IO from page reclaim may indicate that the system is seriously under provisioned for... 8 Jun 2010 05:50
[PATCH 4/5] ACPI / ACPICA: Fix GPE initialization
From: Rafael J. Wysocki <rjw(a)sisk.pl> While developing the GPE reference counting code we overlooked the fact that acpi_ev_update_gpes() could have enabled GPEs before acpi_ev_initialize_gpe_block() was called. As a result, some GPEs are enabled twice during the initialization. To fix this issue avoid calling... 8 Jun 2010 05:50

[RFC PATCH 0/6] Do not call ->writepage[s] from direct reclaim and use a_ops->writepages() where possible
I finally got a chance last week to visit the topic of direct reclaim avoiding the writing out pages. As it came up during discussions the last time, I also had a stab at making the VM writing ranges of pages instead of individual pages. I am not proposing for merging yet until I want to see what people think of th... 8 Jun 2010 05:50
[PATCH 3/5] ACPI / ACPICA: Avoid writing full enable masks to GPE registers
From: Rafael J. Wysocki <rjw(a)sisk.pl> ACPICA uses acpi_hw_write_gpe_enable_reg() to re-enable a GPE after an event signaled by it has been handled. However, this function writes the entire GPE enable mask to the GPE's enable register which may not be correct. Namely, if one of the other GPEs in the same regist... 8 Jun 2010 05:50
