This change will simplifyimplementation by removing duplicated code with generic ioremap_prot() andiounmap(), and has the equivalent functioality.For hexagon, the current ioremap() and iounmap() are the same as genericversion. After taking GENERIC_IOREMAP way, the old ioremap() andiounmap() can be completely removed.Link: https://lkml.kernel.org/r/20230706154520.11257-3-bhe@redhat.comSigned-off-by: Baoquan He Cc: Brian Cain Cc: Alexander Gordeev Cc: Arnd Bergmann Cc: Catalin Marinas Cc: Christian Borntraeger Cc: Christophe Leroy Cc: Christoph Hellwig Cc: Chris Zankel Cc: David Laight Cc: Geert Uytterhoeven Cc: Gerald Schaefer Cc: Heiko Carstens Cc: Helge Deller Cc: "James E.J.

a050ba1e - mm/fault: convert remaining simple cases to lock_mm_and_find_vma()

Sat, 24 Jun 2023 17:55:38 +0000

mm/fault: convert remaining simple cases to lock_mm_and_find_vma()This does the simple pattern conversion of alpha, arc, csky, hexagon,loongarch, nios2, sh, sparc32, and xtensa to the lock_mm_and_find_vma()helper. They all have the regular fault handling pattern without oddspecial cases.The remaining architectures all have something that keeps us from astraightforward conversion: ia64 and parisc have stacks that can growboth up as well as down (and ia64 has special address region checks).And m68k, microblaze, openrisc, sparc64, and um end up having extrarules about only expanding the stack down a limited amount below theuser space stack pointer. That is something that x86 used to do too(long long ago), and it probably could just be skipped, but it stillmakes the conversion less than trivial.Note that this conversion was done manually and with the exception ofalpha without any build testing, because I have a fairly limited cross-building environment. The cases are all simple, and I went through thechanges several times, but...Signed-off-by: Linus Torvalds List of files: /linux-6.15/arch/hexagon/Kconfig

0774a6ed - timekeeping: default GENERIC_CLOCKEVENTS to enabled

Thu, 24 Sep 2020 09:32:40 +0000

timekeeping: default GENERIC_CLOCKEVENTS to enabledAlmost all machines use GENERIC_CLOCKEVENTS, so it feels wrong torequire each one to select that symbol manually.Instead, enable it whenever CONFIG_LEGACY_TIMER_TICK is disabled asa simplification. It should be possible to select bothGENERIC_CLOCKEVENTS and LEGACY_TIMER_TICK from an architecture nowand decide at runtime between the two.For the clockevents arch-support.txt file, this means that additionalarchitectures are marked as TODO when they have at least one machinethat still uses LEGACY_TIMER_TICK, rather than being marked 'ok' whenat least one machine has been converted. This means that both m68k andarm (for riscpc) revert to TODO.At this point, we could just always enable CONFIG_GENERIC_CLOCKEVENTSrather than leaving it off when not needed.
