This patch fixes several problems in the call path of
netpoll_send_skb_on_dev():
1. We already disable IRQ's before calling netpoll_send_skb_on_dev(),
so we don't need to disable IRQ's again.
2. All the callees of netpoll_send_skb_on_dev() should use
rcu_dereference_bh() to dereference
The logic of the code is same, just call netpoll_rx_on().

Like the previous patch, slave_disable_netpoll() and __netpoll_cleanup()

So,
This is a proposition to handle the cputime accounting without the
tick to prepare for stopping the tick further idle.
I have managed to reuse and generalize the kernel/user boundary
hooks used by RCU. This way we can minimize the changes in archs
that don't support virtual cputime and we
Create a new subsystem that handles the hooks on kernel/user
boundaries currently used by RCU for its userspace extended
quiescent state.
We need to pull this up from RCU into this new level of indirection
because these hooks are also going to be used to implement an "on
demand" generic virtual
We may soon be able to run both at the same time. But we need
to rework a bit the irq finegrained accounting before that.
Just do a mutual exclusion for now.

account_system_vtime() can be called from random places:
hard/softirq entry/exit, kvm guest entry/exit, and even
context switches on powerpc.
Rename it to the even more generic account_vtime() name,
this reflect well that we are in a random place in the
kernel where we have either system, idle or
If we want to stop the tick further idle, we need to be
able to account the cputime without using the tick.
Virtual based cputime accounting solves that problem by
hooking into kernel/user boundaries.
However implementing CONFIG_VIRT_CPU_ACCOUNTING requires
to set low level hooks and involves
Allow to dynamically switch between tick and virtual based cputime accounting.
This way we can provide a kind of "on-demand" virtual based cputime
accounting. In this mode, the kernel will rely on the user hooks
subsystem to dynamically hook on kernel boundaries.
This is in preparation for beeing

has provided invalid information. However, on some machines the overrides
may do more harm than good due to configuration differences between machines

migrate_pages() can return positive value while at the same time emptying
the list of pages it was called with. Such situation means that it went
through all the pages on the list some of which failed to be migrated.
If that happens, __alloc_contig_migrate_range()'s loop may finish without
An Andre To Remember
July 2012
Linux lost a friend and advocate this month. Though never a household
name, Andre Hedrick had a positive impact on everyone today running
Linux, or using a website, with any form of IDE (ATA) or SCSI storage
-- that means millions upon millions of
migrate_pages() should return number of pages not migrated or error code.
When unmap_and_move return -EAGAIN, outer loop is re-execution without
initialising nr_failed. This makes nr_failed over-counted.
So this patch correct it by initialising nr_failed in outer loop.
migrate_huge_pages() is
do_migrate_pages() can return the number of pages not migrated.
Because migrate_pages() syscall return this value directly,
migrate_pages() syscall may return the number of pages not migrated.
In fail case in migrate_pages() syscall, we should return error value.
So change err to -EBUSY
move_pages() syscall may return success in case that
do_move_page_to_node_array return positive value which means migration failed.
This patch changes return value of do_move_page_to_node_array
for not returning positive value. It can fix the problem.

The behavior of the SMC has changed several times over the years,
causing read failures in the driver. It seems the problem can be
explained by a shift in SMC speed combined with improper action on
status codes.
We should first wait for the SMC to settle, which was the most
frequent response on

Ah, also, as per the documentation in the kernel (go look, it's there),

Hi James,
Please pull from this new branch and ignore the 7-25-12 branch. This
new branch includes fixes for comments by hpa. I've also included one
additional patch from [1] to close a race and prevent possibly sensitive
data from being free'd before being zeroed. I'm attaching this entire

This patch adds the support to use power supply attributes registration
mechanism for battery properties. This will be useful if the platform
has a main/primary battery and it relies on smb347 driver to get
some critical battery attributes.
Anton, I have to rework on this patch once we get an
This patch adds the support to report the battery power supply attributes
STATUS and CHARGE_TYPE. This patch makes use of power_supply_get_external_attr()
API to get these attributes through power supply core.

This patchset promtes the zcache driver from staging to drivers/mm/.
zcache captures swap pages via frontswap and pages that fall
out of the page cache via cleancache and compress them in RAM,
providing a compressed RAM swap and a compressed second-chance
page cache.

This patchset creates a new driver class under drivers/ for
memory management related drivers, like zcache.
This driver class would be for drivers that don't actually enabled
a hardware device, but rather augment the memory manager in some
way.
In-tree candidates for this driver class are

This patch promotes the slab-based zsmalloc memory allocator
from the staging tree to mm/
zcache depends on this allocator for storing compressed RAM pages
in an efficient way under system wide memory pressure where
high-order (greater than 0) page allocation are very likely to
fail.
