Hi Linus,
please pull the following set of fixes and enhancements for the
parisc architecture for 6.1-rc1:
Fixes:
- When we added basic vDSO support in kernel 5.18 we introduced a bug
which prevented a mmap() of graphic card memory. This is because we
used the DMB (data memory break trap bit) page flag as special-bit, but
missed to clear that bit when loading the TLB.
- Graphics card memory size was not correctly aligned
- Spelling fixes (from Colin Ian King)
Enhancements:
- PDC console (which uses firmware calls) now rewritten as early console
- Reduced size of alternative tables
Thanks,
Helge
