Subject: [GIT PULL] parisc architecture updates for kernel v5.4

Hi Linus,

please pull the parisc architecture updates for kernel 5.4 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.4-1

Major changes:
* Make the powerpc implementation to read elf files available as a public
  kexec interface so it can be re-used on other architectures (Sven)
* Implement kexec on parisc (Sven)
* Add kprobes on ftrace on parisc (Sven)
* Fix kernel crash with HSC-PCI cards based on card-mode Dino
* Add assembly implementations for memset, strlen, strcpy, strncpy and strcat
* Some cleanups, documentation updates, warning fixes, ...

Thanks,
Helge
