Hi Linus,

please pull fixes and updates for the parisc architecture for kernel 4.19 from:

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.19-1

Changes include:
- parisc now uses the generic dma_noncoherent_ops implementation, by Christoph Hellwig.
- further memory barrier and spinlock improvements, by John David Anglin.
- prepare removal of current_text_addr() functions, by Nick Desaulniers.
- improve kernel stack unwinding on parisc, by me.
- drop ENOTSUP which was defined on parisc only, by me.

Thanks,
Helge
