Alexandre Ghiti b64d23d1b9 riscv: Use an atomic xchg in pudp_huge_get_and_clear() 
commit 546e42c8c6d9498d5eac14bf2aca0383a11b145a upstream.

Make sure we return the right pud value and not a value that could
have been overwritten in between by a different core.

[pjw@kernel.org: use xchg rather than atomic_long_xchg; avoid atomic op for !CONFIG_SMP like x86]

README

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.
