The r4k variant of local_flush_tlb_mm() wraps its call to drop_mmu_context() with a preempt_disable() & preempt_enable() pair, but this is redundant since drop_mmu_context() disables interrupts and from Documentation/preempt-locking.txt: Note that you do not need to explicitly prevent preemption if you are holding any locks or interrupts are disabled, since preemption is implicitly disabled in those cases. Remove the redundant preempt_disable() & preempt_enable() calls. Signed-off-by: Paul Burton <paul.burton@mips.com> Cc: linux-mips@vger.kernel.org
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
