+
+[ Upstream commit 899a42f836678a595f7d2bc36a5a0c2b03d08cbc ]
+
+Move lookup_processor_type() out of the __init section so it is callable
+from (eg) the secondary startup code during hotplug.

+Subject: arm64: remove no-op -p linker flag
+
+(commit 1a381d4a0a9a0f999a13faaba22bf6b3fc80dcb9 upstream)
+
+Linking the ARM64 defconfig kernel with LLVM lld fails with the error:
+
+ ld.lld: error: unknown argument: -p
+ Makefile:1015: recipe for target 'vmlinux' failed
+
+Without this flag, the ARM64 defconfig kernel successfully links with
+lld and boots on Dragonboard 410c.
+
+After digging through binutils source and changelogs, it turns out that
+-p is only relevant to ancient binutils installations targeting 32-bit
+ARM. binutils accepts -p for AArch64 too, but it's always been
+undocumented and silently ignored. A comment in
+ld/emultempl/aarch64elf.em explains that it's "Only here for backwards
+compatibility".
+
+Since this flag is a no-op on ARM64, we can safely drop it.

+When VPHN function is not supported and during cpu hotplug event,

+ offset
+
+[ Upstream commit 1a413646931cb14442065cfc17561e50f5b5bb44 ]
+
+Other filesystems such as ext4, f2fs and ubifs all return ENXIO when
+lseek (SEEK_DATA or SEEK_HOLE) requests a negative offset.
+
+man 2 lseek says
+
+: EINVAL whence is not valid. Or: the resulting file offset would be
+: negative, or beyond the end of a seekable device.
+:
+: ENXIO whence is SEEK_DATA or SEEK_HOLE, and the file offset is beyond
+: the end of the file.
+
+Make tmpfs return ENXIO under these circumstances as well. After this,
+tmpfs also passes xfstests's generic/448.
