Add unlikely() hint to the _TIF_MTE_ASYNC_FAULT flag check in el0_svc_common() since asynchronous MTE faults are expected to be rare occurrences during normal system call execution. This optimization helps the compiler to improve instruction caching and branch prediction for the common case where no asynchronous MTE faults are pending, while maintaining correct behavior for the exceptional case where such faults need to be handled prior to system call execution.

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 reStructuredText 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.
