This patch has no any functionality changes but refactors hist entry

It renames function "valid_hitm_or_store()" to "is_valid_hist_entry()",
changes return type from integer type to bool type. In the function,
it uses switch-case instead of ternary operators,

Previously, we rounded down the number of sectors just before calling

are not split in the middle of a data unit, it makes it possible

This patch adds several local variables:

The macro DISPLAY_HITM() is used to calculate HITM percentage introduced
by every node and it's shown for the node info.

This patch series is for several minor code refactoring, which is
extracted from the patch series "perf c2c: Sort cacheline with all

the only consumer for soring with all loads, this is the reason in this

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.
This is the second (and last) of 2 sets.
v3:
- Make use of 'ret' instead of removing it
- Use __always_unused instead of removing unused

Add a kernel option SYSTEM_BLACKLIST_AUTH_UPDATE to enable the root user
to dynamically add new keys to the blacklist keyring. This enables to

from being trusted in a PKCS#7 certificate chain. This also

Before exposing this new key type to user space, make sure that only

Factor out the blacklist hash creation with the get_raw_hash() helper.
This also centralize the "tbs" and "bin" prefixes and make them private,
which help to manage them consistently.

Hello,
there are no known active users of the efm32 platform. Given that the
only machine that is supported has only 4 MiB of RAM its use is also
quite limited.
Back then it served as the platform to develop ARMv7-M support in Linux
which was quite fun and still is a
Support for this machine was just removed, so drop the now unused timer
