In a later patch we want to introduce a syntax that allows updating
attribute fields by an index pointing to a certain u64 entry of struct
perf_event_attr. We need this to expose any event via sysfs that is

This series cleans up non-portable 'echo -e' usage.
I haven't replaced all instances of 'echo -e' though:

- those that invoke echo by full path (/bin/echo) probably know what they do;
- those that output user help don't affect build.

Hi all,
I'm running Linux 3.10.7 and have encountered the following NULL pointer
dereference. So far it has only occurred once, so I cannot reproduce the
circumstances that cause the problem.
Please keep me on CC: as I'm not subscribed to LKML.
Cheers,

The patch consists of two parts. The first part introduces higher degree of
parallelism to the usages of the mb_cache and mb_cache_entries and impacts
all ext filesystems.
The second part of the patch further increases the scalablity of an ext4
filesystem by having each ext4 fielsystem allocate a

I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
that it is much cleaner to have this in the core. This also removes a
circular dependency between the helpers and the core, and so we can
finally register child nodes in the core instead of doing this manually
in each driver. S

If the WAKEUP_INT is asserted at wakeup and not cleared, we'll end up
looping around forever. This has been seen to happen on exynos5420
silicon despite the fact that we haven't enabled any wakeup events due
to a silicon errata. It is safe to do on all exynos variants.
