SPRN_M_TWB contains the address of task PGD minus an offset which compensates the offset required when accessing the kernel PGDIR. However, since commitac9f97ff8b("powerpc/8xx: Inconditionally use task PGDIR in DTLB misses") and commit33c527522f("powerpc/8xx: Inconditionally use task PGDIR in ITLB misses") kernel PGDIR is not used anymore in hot paths. Remove this offset which was added by commitfde5a9057f("powerpc/8xx: Optimise access to swapper_pg_dir") Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> [maddy: Fixed checkpatch.pl warning for "pathes"] Signed-off-by: Madhavan Srinivasan <maddy@linux.ibm.com> Link: https://patch.msgid.link/9710d960b512996e64beebfd368cfeaadb28b3ba.1755509047.git.christophe.leroy@csgroup.eu
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.
