Pull parisc architecture updates from Helge Deller: - add vDSO support (allows us to use non-executable stacks) - many TLB and cache flush optimizations (by Dave Anglin) - fix handling of probe non-access faults (by Dave Anglin) - fix invalidate/flush vmap routines (by Dave Anglin) - avoid using hardware single-step in kprobes - enable ARCH_HAS_DEBUG_VM_PGTABLE - many cleanups in unaligned handlers, e.g. rewrite of existing assembly code - always use the self-extracting kernel feature - big refacturing and code reductions regarding space-register usage in get_user() and put_user() - add fillrect() support to stifb graphics driver * tag 'for-5.18/parisc-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: (23 commits) parisc: Fix invalidate/flush vmap routines parisc: Avoid flushing cache on cache-less machines parisc: Avoid using hardware single-step in kprobes parisc: Improve CPU socket and core bootup info text parisc: Enable ARCH_HAS_DEBUG_VM_PGTABLE parisc: Avoid calling SMP cache flush functions on cache-less machines parisc: Increase parisc_cache_flush_threshold setting parisc/unaligned: Enhance user-space visible output parisc/unaligned: Rewrite 32-bit inline assembly of emulate_sth() parisc/unaligned: Rewrite 32-bit inline assembly of emulate_ldd() parisc/unaligned: Rewrite inline assembly of emulate_ldw() parisc/unaligned: Rewrite inline assembly of emulate_ldh() parisc/unaligned: Use EFAULT fixup handler in unaligned handlers parisc: Reduce code size by optimizing get_current() function calls parisc: Use constants to encode the space registers like SR_KERNEL parisc: Use SR_USER and SR_KERNEL in get_user() and put_user() parisc: Add defines for various space register parisc: Always use the self-extracting kernel feature video/fbdev/stifb: Implement the stifb_fillrect() function parisc: Add vDSO support ...
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.
