I'd move this up to the top of the function, and just return 0 - there's

This series follows the same approach as taken on Tegra and
OMAP DT files to use the C preprocessor in order to improve
readability. Since bcm281xx does not yet have gpio and pinctrl
support, this series just enables the C preprocessor and removes
the magic constants from existing irq properties.
Use the standard interrupt-controller and ARM GIC constants to
improve the readability of bcm281xx DT irq properties.

Since '1c0fe6e mm: invoke oom-killer from page fault', page fault
handlers should not directly kill faulting tasks in an out of memory
condition. Instead, they should be invoking the OOM killer to pick
the right task. Convert the remaining architectures.

In mmp pdma, phy channels are allocated/freed dynamically.
The mapping from DMA request to DMA channel number in DRCMR
should be cleared when a phy channel is freed. Otherwise
conflicts will happen when:
1. A is using channel 2 and free it after finished, but A
still maps to

The patch I tested on OVMF,
From: Xiang Wang
This patch set deals with the issues that 1) phy channels are not protected
in mmp_pdma. 2) dma request<->channel mapping is not cleared when a phy chan
is freed.

dma: mmp_pdma: add protect when alloc/free phy channels

Hi guys,
I noticed the following warning in a linux-next build:
fs/ext4/inode.c: In function 'ext4_da_writepages':
fs/ext4/inode.c:2212:6: warning: 'err' may be used uninitialized in this
function [-Wmaybe-uninitialized]
In tracking this down, I followed the call chains and discovered that
When a PCI host bridge device receives a Bus Check notification, we
must re-enumerate starting with the bridge to discover changes (devices
that have been added or removed).
Prior to 668192b678 ("PCI: acpiphp: Move host bridge hotplug to
pci_root.c"), this happened in
This patch-set try to support physically hot-plug/unplug
a cpu automatically, that is:
if you offline a cpu, it will automatically actually remove
a cpu, and if you hot-plug a cpu, then it will online this
cpu automatically.
so, offline is just like eject, but eject attribute seems not
available
