Pull powerpc fixes from Michael Ellerman: - A fix for unrecoverable SLB faults in the interrupt exit path, introduced by the recent rewrite of interrupt exit in C. - Four fixes for our KUAP (Kernel Userspace Access Prevention) support on 64-bit. These are all fairly minor with the exception of the change to evaluate the get/put_user() arguments before we enable user access, which reduces the amount of code we run with user access enabled. - A fix for our secure boot IMA rules, if enforcement of module signatures is enabled at runtime rather than build time. - A fix to our 32-bit VDSO clock_getres() which wasn't falling back to the syscall for unknown clocks. - A build fix for CONFIG_PPC_KUAP_DEBUG on 32-bit BookS, and another for 40x. Thanks to: Christophe Leroy, Hugh Dickins, Nicholas Piggin, Aurelien Jarno, Mimi Zohar, Nayna Jain. * tag 'powerpc-5.7-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/40x: Make more space for system call exception powerpc/vdso32: Fallback on getres syscall when clock is unknown powerpc/32s: Fix build failure with CONFIG_PPC_KUAP_DEBUG powerpc/ima: Fix secure boot rules in ima arch policy powerpc/64s/kuap: Restore AMR in fast_interrupt_return powerpc/64s/kuap: Restore AMR in system reset exception powerpc/64/kuap: Move kuap checks out of MSR[RI]=0 regions of exit code powerpc/64s: Fix unrecoverable SLB crashes due to preemption check powerpc/uaccess: Evaluate macro arguments once, before user access is allowed
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.
