Merge branch 'parisc-4.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller: "Major changes include: - Full support of the firmware Page Deallocation Table with MADV_HWPOISON and MADV_SOFT_OFFLINE. A kernel thread scans regularily for new bad memory pages. - Full support for self-extracting kernel. - Added UBSAN support. - Lots of section mismatch fixes across all parisc drivers. - Added examples for %pF and %pS usage in printk-formats.txt" * 'parisc-4.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: (28 commits) printk-formats.txt: Add examples for %pF and %pS usage parisc: Fix up devices below a PCI-PCI MegaRAID controller bridge parisc/core: Fix section mismatches parisc/ipmi_si_intf: Fix section mismatches on parisc platform parisc/input/hilkbd: Fix section mismatches parisc/net/lasi_82596: Fix section mismatches parisc/serio: Fix section mismatches in gscps2 and hp_sdc drivers parisc: Fix section mismatches in parisc core drivers parisc/parport_gsc: Fix section mismatches parisc/scsi/lasi700: Fix section mismatches parisc/scsi/zalon: Fix section mismatches parisc/8250_gsc: Fix section mismatches parisc/mux: Fix section mismatches parisc/sticore: Fix section mismatches parisc/harmony: Fix section mismatches parisc: Wire up support for self-extracting kernel parisc: Make existing core files reuseable for bootloader parisc: Add core code for self-extracting kernel parisc: Enable UBSAN support parisc/random: Add machine specific randomness ...
