Konstantin Belousov 4d22d07a07 Add support for usermode (vdso-like) gettimeofday(2) and ... clock_gettime(2) on ARMv7 and ARMv8 systems which have architectural generic timer hardware. It is similar how the RDTSC timer is used in userspace on x86. Fix a permission problem where generic timer access from EL0 (or userspace on v7) was not properly initialized on APs. For ARMv7, mark the stack non-executable. The shared page is added for all arms (including ARMv8 64bit), and the signal trampoline code is moved to the page.
