hexagon: simplify asm/io.h for !HAS_IOPORT

2024-10-28T21:44:29Z

Hexagon fails to build after the final patch that makes CONFIG_HAS_IOPORT optional: In file included from arch/hexagon/include/asm/io.h:328: include/asm-generic/io.h:854:18: error: static declaration of 'ioread8' follows non-static declaration 854 | static inline u8 ioread8(const volatile void __iomem *addr) | ^ include/asm-generic/io.h:853:17: note: expanded from macro 'ioread8' 853 | #define ioread8 ioread8 | ^ include/asm-generic/iomap.h:29:21: note: previous declaration is here 29 | extern unsigned int ioread8(const void __iomem *); | ^ As it turns out, most of its asm/io.h and lib/io.c files is redundant now, and just removing all that makes it build again. As with the other architectures, defining the __raw_readl()/__raw_writel() type functions instead of the non-__raw ones is better here for consistency. Signed-off-by: Arnd Bergmann

hexagon: Don't select GENERIC_IOMAP without HAS_IOPORT support

2024-10-28T21:44:27Z

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. As hexagon does not support I/O port access it also the GENERIC_IOMAP mechanism of dynamically choosing between I/O port and MMIO access doesn't work so don't select it.

arch: consolidate existing CONFIG_PAGE_SIZE_*KB definitions

These four architectures define the same Kconfig symbols for configuring the page size. Move the logic into a common place where it can be shared with all other architectures. Reviewed-by: Thomas Gleixner Signed-off-by: Arnd Bergmann

hexagon: select GENERIC_IRQ_PROBE instead of redefining it

hexagon: select FRAME_POINTER instead of redefining it

2024-02-20T11:47:45Z

Because FRAME_POINTER is defined in lib/Kconfig.debug, the arch Kconfig should select it. Add 'select FRAME_POINTER' to HEXAGON. ARCH_WANT_FRAME_POINTERS must also be selected to avoid the unmet dependency warning. Signed-off-by: Masahiro Yamada Reviewed-by: Randy Dunlap Acked-by: Brian Cain

hexagon: mm: convert to GENERIC_IOREMAP

2023-08-18T17:12:32Z

By taking GENERIC_IOREMAP method, the generic ioremap_prot() and iounmap() are visible and available to arch. This change will simplify implementation by removing duplicated code with generic ioremap_prot() and iounmap(), and has the equivalent functioality. For hexagon, the current ioremap() and iounmap() are the same as generic version. After taking GENERIC_IOREMAP way, the old ioremap() and iounmap() can be completely removed.

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

2023-06-24T21:12:58Z

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 odd special cases. The remaining architectures all have something that keeps us from a straightforward conversion: ia64 and parisc have stacks that can grow both up as well as down (and ia64 has special address region checks). And m68k, microblaze, openrisc, sparc64, and um end up having extra rules about only expanding the stack down a limited amount below the user space stack pointer. That is something that x86 used to do too (long long ago), and it probably could just be skipped, but it still makes the conversion less than trivial. Note that this conversion was done manually and with the exception of alpha without any build testing, because I have a fairly limited cross- building environment. The cases are all simple, and I went through the changes several times, but... Signed-off-by: Linus Torvalds

uaccess: remove CONFIG_SET_FS

2022-02-25T08:36:06Z

There are no remaining callers of set_fs(), so CONFIG_SET_FS can be removed globally, along with the thread_info field and any references to it. This turns access_ok() into a cheaper check against TASK_SIZE_MAX. As CONFIG_SET_FS is now gone, drop all remaining references to set_fs()/get_fs(), mm_segment_t, user_addr_max() and uaccess_kernel(). Acked-by: Sam Ravnborg # for sparc32 changes Acked-by: "Eric W.
