arch/sh/include/asm/io.h: provide prototypes for PCI I/O mapping in asm/io.h

2018-12-14T23:05:45+00:00

Most architectures provide prototypes for the PCI I/O mapping operations
when asm/io.h is included but SH doesn't currently do that, leading to
for example warnings in sound/pci/hda/patch_ca0132.c when pci_iomap() is
used on current -next.  Make SH more consistent with other architectures
by including asm-generic/pci_iomap.h in asm/io.h.

treewide: remove current_text_addr

2018-10-31T15:54:12+00:00

Prefer _THIS_IP_ defined in linux/kernel.h.

Most definitions of current_text_addr were the same as _THIS_IP_, but
a few archs had inline assembly instead.

This patch removes the final call site of current_text_addr, making all
of the definitions dead code.

hugetlb: introduce generic version of huge_ptep_get

2018-10-26T23:26:34+00:00

ia64, mips, parisc, powerpc, sh, sparc, x86 architectures use the same
version of huge_ptep_get, so move this generic implementation into
asm-generic/hugetlb.h.
