parisc architecture updates for v4.9-rc1
Hi Linus,
please pull the updates for 4.9-rc1 for the parisc architecture from:
git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.9-1
Changes include:
- Fix boot of 32bit SMP kernel (initial kernel mapping was too small)
- Added hardened usercopy checks
- Drop bootmem and switch to memblock and NO_BOOTMEM implementation
- Drop the BROKEN_RODATA config option (and thus remove the relevant code from the generic headers and files because parisc was the last architecture which used this config option)
- Improve segfault reporting by printing human readable error strings
- Various smaller changes, e.g. dwarf debug support for assembly code, update comments regarding copy_user_page_asm, switch to kmalloc_array()
Thanks,
Helge
