ARM: socfpga: mark secondary_trampoline as cpuinit The socfpga_boot_secondary is correctly marked as __cpuinit but references secondary_trampoline, which was introduced into the init section, causing this build warning: WARNING: vmlinux.o(.cpuinit.text+0xf90): Section mismatch in reference from the function socfpga_boot_secondary() to the variable .init.text:secondary_trampoline The function __cpuinit socfpga_boot_secondary() references a variable __init secondary_trampoline. If secondary_trampoline is only used by socfpga_boot_secondary then annotate secondary_trampoline with a matching annotation. The solution is to mark secondary_trampoline as cpuinit as well.

ARM: socfpga: fix build break for allyesconfig Building a multiplatform kernel with combined armv7 and armv6 kernel does not work with the socfpga smp code, which contains v7-only instructions. Since this code never runs on armv6, we can annotate the assmebly with .arch armv7-a, as suggested by Russell King.
