h8300: remove stale bindings and symlink (2022-05-20 22:40:56 +0200)
----------------------------------------------------------------
asm-generic changes for 5.19
The asm-generic tree contains three separate changes for linux-5.19:
- The h8300 architecture is retired after it has been effectively
unmaintained for a number of years. This is the last architecture we
supported that has no MMU implementation, but there are still a few
architectures (arm, m68k, riscv, sh and xtensa) that support CPUs with
and without an MMU.
- A series to add a generic ticket spinlock that can be shared by most
architectures with a working cmpxchg or ll/sc type atomic, including
the conversion of riscv, csky and openrisc. This series is also a
prerequisite for the loongarch64 architecture port that will come as
a separate pull request.
- A cleanup of some exported uapi header files to ensure they can be
included from user space without relying on other kernel headers.
----------------------------------------------------------------
Arnd Bergmann (4):
Merge branch 'remove-h8300' of
git://git.infradead.org/users/hch/misc into asm-generic
Merge tag 'generic-ticket-spinlocks-v6' of
git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux into
asm-generic
Merge branch 'asm-generic-headers-cleanup' into asm-generic
h8300: remove stale bindings and symlink
Christoph Hellwig (1):
remove the h8300 architecture
