Merge branch 'parisc-5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller:
"A change to increase the default maximum stack size on parisc to 100MB
and the ability to further increase the stack hard limit size at
runtime with ulimit for newly started processes.
The other patches fix compile warnings, utilize the Kbuild logic and
cleanups the parisc arch code"
* 'parisc-5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: pci-dma: fix warning unused-function
parisc/uapi: Use Kbuild logic to provide <asm/types.h>
parisc: Make user stack size configurable
parisc: Use _TIF_USER_WORK_MASK in entry.S
parisc: Drop loops_per_jiffy from per_cpu struct
