Dave Martin cd849ae9cd ARM: 6518/1: kexec: Fix crash_setup_regs() for ARMv7 and CONFIG_THUMB2_KERNEL ... * Fix kexec build failure with CONFIG_THUMB2_KERNEL. * Avoids deprecated/forbidden sp and pc usage in for ARMv7 onwards, retaining compatibility with older architecture versions. * The pc value saved to newregs is now aligned on a predictable instruction boundary. (stmia { ... pc } or str pc has implementation-defined results in most versions of the ARM architecutre, and is prohibited (unpredictable) in Thumb-2.) * Switch to named inline asm arguments (else I get readily confused ...) The resulting code should be compatible with all architecture versions >= v3, with or without CONFIG_THUMB2_KERNEL.
