alpha: no need to include asm/xchg.h twice

2024-08-19T07:45:27Z

We used to generate different helpers for local and full {cmp,}xchg(); these days the barriers are in arch_{cmp,}xchg() instead and generated helpers are identical for local and full cases. No need for those parametrized includes of asm/xchg.h - we might as well insert its contents directly in asm/cmpxchg.h and do it only once. Signed-off-by: Al Viro

alpha: fix ioread64be()/iowrite64be() helpers

2024-08-01T13:48:03Z

Compile-testing the crypto/caam driver on alpha showed a pre-existing problem on alpha with iowrite64be() missing: ERROR: modpost: "iowrite64be" [drivers/crypto/caam/caam_jr.ko] undefined! The prototypes were added a while ago when we started using asm-generic/io.h, but the implementation was still missing. At some point the ioread64/iowrite64 helpers were added, but the big-endian versions are still missing, and the generic version (using readq/writeq) is would not work here. Change it to wrap ioread64()/iowrite64() instead. Fixes: beba3771d9e0 ("crypto: caam: Make CRYPTO_DEV_FSL_CAAM dependent of COMPILE_TEST") Fixes: e19d4ebc536d ("alpha: add full ioread64/iowrite64 implementation") Fixes: 7e772dad9913 ("alpha: Use generic ") Closes: https://lore.kernel.org/all/CAHk-=wgEyzSxTs467NDOVfBSzWvUS6ztcwhiy=M3xog==KBmTw@mail.gmail.com/ Tested-by: Guenter Roeck Reviewed-by: Linus Walleij Signed-off-by: Arnd Bergmann

alpha: drop pre-EV56 support

2024-05-06T10:05:00Z

All EV4 machines are already gone, and the remaining EV5 based machines all support the slightly more modern EV56 generation as well. Debian only supports EV56 and later. Drop both of these and build kernels optimized for EV56 and higher when the "generic" options is selected, tuning for an out-of-order EV6 pipeline, same as Debian userspace. Since this was the only supported architecture without 8-bit and 16-bit stores, common kernel code no longer has to worry about aligning struct members, and existing workarounds from the block and tty layers can be removed. The alpha memory management code no longer needs an abstraction for the differences between EV4 and EV5+. Link: https://lists.debian.org/debian-alpha/2023/05/msg00009.html Acked-by: Paul E.

alpha: cabriolet: remove EV5 CPU support

2024-05-03T20:10:03Z

The sys_cabriolet.c file includes support for multiple evaluation boards. pc164 and lx164 are for ev56 CPUs, while the eb164 is now the last supported machine that only supports ev5 but not ev56. Acked-by: Paul E. McKenney Acked-by: Matt Turner Signed-off-by: Arnd Bergmann

alpha: remove LCA and APECS based machines

2024-05-03T20:09:59Z

APECS is the DECchip 21071x chipset for the EV4 and EV45 generation, while LCA is the integrated I/O support on the corresponding low-cost alpha machines of that generation. All of these CPUs lack the BWX extension for byte and word access, so drop the chipset support and all associated machines. Acked-by: Paul E.

alpha: sable: remove early machine support

2024-05-03T20:09:55Z

The sable family (Alphaserver 2000 and 2100) comes in variants for EV4, EV45, EV5 and EV56. Drop support for the earlier ones that lack support for the BWX extension but keep the later 'gamma' variant around since that works with EV56 CPUs. Acked-by: Paul E.

alpha: remove DECpc AXP150 (Jensen) support

2024-05-03T20:09:50Z

This is one of the hackiest Alpha machines, and the only one without PCI support. Removing this allows cleaning up code in eise and tty drivers in addition to the architecture code. Acked-by: Paul E. McKenney Acked-by: Matt Turner Signed-off-by: Arnd Bergmann

alpha: sort scr_mem{cpy,move}w() out

2024-05-03T20:08:50Z

Take scr_memmove() out of line, make both it and scr_memcpyw() conditional upon VGA_CONSOLE or MDA_CONSOLE (if neither is selected, we are certain to be working with the kernel-allocated buffer rather than VRAM and defaults will work just fine). That allows to clean vt_buffer.h, but that's a separate story Signed-off-by: Al Viro Acked-by: Paul E. McKenney Acked-by: Matt Turner Signed-off-by: Arnd Bergmann

arch: define CONFIG_PAGE_SIZE_*KB on all architectures

2024-03-06T18:29:09Z

Most architectures only support a single hardcoded page size. In order to ensure that each one of these sets the corresponding Kconfig symbols, change over the PAGE_SHIFT definition to the common one and allow only the hardware page size to be selected.

Merge branch 'asm-generic-prototypes' into asm-generic

2023-11-28T17:25:37Z

As part of my quest to enable -Wmissing-prototypes by default, these patches clean up some of the prototypes that are needed by all architectures but are handled inconsistently. The duplicate prototypes are moved into common code, which helps both to clean up the existing warnings and simplifies the logic. * asm-generic-prototypes: arm64: vdso32: Define BUILD_VDSO32_64 to correct prototypes csky: fix arch_jump_label_transform_static override arch: add do_page_fault prototypes arch: add missing prepare_ftrace_return() prototypes arch: vdso: consolidate gettime prototypes arch: include linux/cpu.h for trap_init() prototype arch: fix asm-offsets.c building with -Wmissing-prototypes arch: consolidate arch_irq_work_raise prototypes
