Subject: [GIT PULL] parisc architecture fixes and updates for v6.19-rc1

Hi Linus,

please pull a few fixes and updates for the parisc architecture for 6.19-rc1.

A fix which allows booting on the very old 710 workstations, and two fixes in
the syscall entry/exit path which allow to execute 64-bit userspace binaries.
Note that although we currently have a 64-bit (static) kernel to allow more
than 4 GB physical RAM, there is no support for 64-bit userspace for
parisc-linux yet, but Dave and Sven are making slowly progress to port and fix
glibc and gcc.

Thanks!
Helge
