From f13a3664e4d1de8adc1fc82b981ba4699a731fa1 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Mon, 24 Dec 2012 10:51:36 +0530 Subject: [PATCH] CONFIG_GENERIC_SIGALTSTACK build breakage with asm-generic/syscalls.h Saner transition plan for GENERIC_SIGALTSTACK conversion - instead of adding #define sys_sigaltstack sys_sigaltstack in asm/syscalls.h of architecture if it's pulls asm-generic/syscalls.h, only to have those defines removed once all architectures are converted, make the declaration in said asm-generic/syscalls.h conditional on the lack of GENERIC_SIGALTSTACK. Less messy in intermediate stages that way...
