This reverts commit 68c4a4f8ab, with
various conflict clean-ups.
With the default root directory mode set to 0750 now, the capability
check was redundant.

Currently only DMESG and CONSOLE record types are protected, and it isn't
obvious that they are using a capability check. Instead switch to explicit
root directory mode of 0750 to keep files private by default. This will
allow the removal of the capability check, which was non-obvious and
forces a process to have possibly too much privilege when simple post-boot
chgrp for readers would be possible without it.

defined features. To disable these compiler options use
cc-option instead of disabling directly. Without using
cc-options upsteam clang would complain about
undefined-optimized and tautological options.

* When wlan_mac.bin is missing for whatever reason, qcacld will fall
back to loading mac address from firmware. The OnePlus firmware can
provide a correct mac address, but it is in reverse, breaking the
qcacld logic.
* Just reverse it back in qcacld. Although wlan_mac.bin should not be
missing at all, we have seen some rare cases where it could not be
generated properly for some reason, and the qcacld fallback is broken
because of byte-ordering. Let's at least make the fallback path work.

This method of building qcacld isn't meant to be used and
causes conflicts with the new OEM profile configuration.
Configuration is now done with drivers/staging/qcacld-3.0/configs.

Android has been benefiting quicker boot from bigger readahead during
boottime than runtime. However, the boottime readahead setting is set
when init is established after treble early mount. This patch will make
readahead bigger by default so early boot can benefit from it. Readahead
will be reset by init on boot_complete.

This option enables a transparent branch optimization
that makes certain almost-always-true or almost-always-false
branch conditions even cheaper to execute within the kernel.
Certain performance-sensitive kernel code, such as trace points,
scheduler functionality, networking code and KVM have such
branches and include support for this optimization technique.
If it is detected that the compiler has support for "asm goto",
the kernel will compile such branches with just a nop instruction.
When the condition flag is toggled to true, the nop will be
converted to a jump instruction to execute the conditional
block of instructions.
This technique lowers overhead and stress on the branchprediction
of the processor and generally makes the kernel faster.
The update of the condition is slower, but those are always
very rare.
