From: David Gibson Date: Thu, 10 Nov 2005 01:56:55 +0000 (+1100) Subject: [PATCH] powerpc: Consolidate asm compatibility macros X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ddfbcf19b15ccd25a0b4b2dc2e38000e08de739;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [PATCH] powerpc: Consolidate asm compatibility macros This patch consolidates macros used to generate assembly for compatibility across different CPUs or configs. A new header, asm-powerpc/asm-compat.h contains the main compatibility macros. It uses some preprocessor magic to make the macros suitable both for use in .S files, and in inline asm in .c files. Headers (bitops.h, uaccess.h, atomic.h, bug.h) which had their own such compatibility macros are changed to use asm-compat.h. ppc_asm.h is now for use in .S files *only*, and a #error enforces that. As such, we're a lot more careless about namespace pollution here than in asm-compat.h. While we're at it, this patch adds a call to the PPC405_ERR77 macro in futex.h which should have had it already, but didn't. Built and booted on pSeries, Maple and iSeries (ARCH=powerpc). Built for 32-bit powermac (ARCH=powerpc) and Walnut (ARCH=ppc).
