Hi Linus,
Please pull the parisc architecture fixes and updates for 6.12-rc1, which
includes:
- On parisc we now use the generic clockevent framework for timekeeping.
- Although there is no 64-bit glibc/userspace for parisc yet, for testing
purposes one can run statically linked 64-bit binaries. This patchset
contains two patches which fix 64-bit userspace which has been broken since
kernel 4.19.
- Fix the userspace stack position and size when the ADDR_NO_RANDOMIZE
personality is enabled.
- On other architectures mmap(MAP_GROWSDOWN | MAP_STACK) creates a
downward-growing stack. On parisc mmap(MAP_STACK) is now sufficient
to create an upward-growing stack.
Thanks!
Helge
