Arnd Bergmann cffaefd15a vdso: Use CONFIG_PAGE_SHIFT in vdso/datapage.h ... Both the vdso rework and the CONFIG_PAGE_SHIFT changes were merged during the v6.9 merge window, so it is now possible to use CONFIG_PAGE_SHIFT instead of including asm/page.h in the vdso. This avoids the workaround for arm64 - commit 8b3843ae36 ("vdso/datapage: Quick fix - use asm/page-def.h for ARM64") and addresses a build warning for powerpc64: In file included from <built-in>:4: In file included from /home/arnd/arm-soc/arm-soc/lib/vdso/gettimeofday.c:5: In file included from ../include/vdso/datapage.h:25: arch/powerpc/include/asm/page.h:230:9: error: result of comparison of constant 13835058055282163712 with expression of type 'unsigned long' is always true [-Werror,-Wtautological-constant-out-of-range-compare] 230 | return __pa(kaddr) >> PAGE_SHIFT; | ^~~~~~~~~~~ arch/powerpc/include/asm/page.h:217:37: note: expanded from macro '__pa' 217 | VIRTUAL_WARN_ON((unsigned long)(x) < PAGE_OFFSET); \ | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~ arch/powerpc/include/asm/page.h:202:73: note: expanded from macro 'VIRTUAL_WARN_ON' 202 | #define VIRTUAL_WARN_ON(x) WARN_ON(IS_ENABLED(CONFIG_DEBUG_VIRTUAL) && (x)) | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~ arch/powerpc/include/asm/bug.h:88:25: note: expanded from macro 'WARN_ON' 88 | int __ret_warn_on = !!(x); \ | ^ Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Kees Cook <keescook@chromium.org> Acked-by: Michael Ellerman <mpe@ellerman.id.au> (powerpc) Link: https://lore.kernel.org/r/20240320180228.136371-1-arnd@kernel.org		History 2024-04-03 21:50:04 +02:00
