This patch adds support for 32-bit applications. The vectors page is a binary blob mapped into the application user space at 0xffff0000 (the AArch64 toolchain does not support compilation of AArch32 code). Full compatibility with ARMv7 user space is supported. The use of deprecated ARMv7 functionality (SWP, CP15 barriers) has been disabled by default on AArch64 kernels and unaligned LDM/STM is not supported. Please note that only the ARM 32-bit EABI is supported, so no OABI compatibility.
