when compiling the topic-leg-uefi kernel [1] with EFI_STUB support for omap2plus_defconfig (to run on a BeagleBone Black with AM335x SoC). I've checked that armv7 supports `isb`, and I've tried the kernel.org 4.6.3-nolibc toolchain [2] and the Linaro gcc-arm-none-eabi-4.8 release. The build goes fine without EFI support. I need some help figuring out what's wrong.
The code should be changed to use the instr_sync macro instead of using the isb instruction directly.
