One patch from John David Anglin which reworks the parisc cache flushing routines with the aim to fix the random segmentation faults on machines with PA8800 and PA8900 processors. We have faced those segfaults since many years, but with this patch no single segfault could be triggered any longer. The patch was tested by 3 people on 5 different machines with various stable kernels (6.6, 6.8 and 6.9). -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQS86RI+GtKfB8BJu973ErUQojoPXwUCZm7t1gAKCRD3ErUQojoP X5KaAQCNbzn2jRVOJnWS2MaoMXikDOT1Mc45++M/BQVKFCd0EAEAhGvLFlmwJA6X h03pyiJ08/8dga/qCBgP8sAEucNP8Ag= =r3iu -----END PGP SIGNATURE----- Merge tag 'parisc-for-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull parisc fix from Helge Deller: "On parisc we have suffered since years from random segfaults which seem to have been triggered due to cache inconsistencies. Those segfaults happened more often on machines with PA8800 and PA8900 CPUs, which have much bigger caches than the earlier machines. Dave Anglin has worked over the last few weeks to fix this bug. His patch has been successfully tested by various people on various machines and with various kernels (6.6, 6.8 and 6.9), and the debian buildd servers haven't shown a single random segfault with this patch. Since the cache handling has been reworked, the patch is slightly bigger than I would like in this stage, but the greatly improved stability IMHO justifies the inclusion now" * tag 'parisc-for-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Try to fix random segmentation faults in package builds |

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.
