The default reader spining threshold is current set to 4096. However,
the right reader spinning threshold may vary from one system to
another and among the different architectures. This patch adds a new
kernel boot parameter to modify the threshold value. This enables
better tailoring to the needs
This patch enables readers to optimistically spin when the
rspin_threshold is non-zero. That threshold value should only
be set when the lock owners of the rwsem are unlikely to go to
sleep. Otherwise enabling reader spinning may make the performance
worse in some cases.

Hi!
This is what I came up with. Changes:
- drop the explicit type marking (u32/u64) - depend on the type
of the mask instead;
- only allow compilation time constant masks;
- barf at "type of register too small to ever match mask" on get;
- rename PUT -> PREP.

Hi Linus,
Can you please pull the fixes from the tag list below? This update
contains fixes for most of the outstanding regressions introduced
with the 4.8-rc1 XFS and iomap infrastructure merge.
The only regression that isn't addressed by this pullreq is the aim7
write regression. I'm still tes
Andrew,
Thanks for picking up this patch series in -mm. Please drop it.
After discussions with Vegard, I have something better now.
Cheers,

Yes, but this actually *removes a bug* in the Linux kernel; if any memory
resource is left to be set up later, it is currently not set up on x86 machines
which don't have PCI busses. That's not very many x86 systems, I'll agree, but
I'm sure some enterprising person is busy creating an SoC whic

Recently we have a new report that, the harddisk can not
resume on time due to firmware issues, and got a kernel
panic because of DPM watchdog timeout. So adjust the
default timeout from 60 to 120 to survive on this platform,
and make DPM_WATCHDOG depending on EXPERT.

As of now linux kernel has late-init call infrastructure which make a

init call at late-init.it is not specific to a platform device.

The 8xx has two special registers called EID (External Interrupt
Disable) and EIE (External Interrupt Enable) for clearing/setting
EE in MSR. It avoids the three instructions set mfmsr/ori/mtmsr or
mfmsr/rlwinm/mtmsr.
We just have to write something in the register to change MSR EE

Hi all,
Changes since 20160818:
The netfilter-next tree lost its build failure.
The jc_docs tree gained a conflict against the drm-misc tree.
The kbuild tree still had its build warnings for PowerPC, for which I
reverted a commit.
