Add the start of libc and libstand for arm64. Not all of the machine dependent functions have been implemented, but this is enough for world. Differential Revision: https://reviews.freebsd.org/D2132 Reviewed by: emaste Sponsored by: The FreeBSD Foundation 2015-04-07 09:52:14 +00:00			`# $FreeBSD$`

Disable support for compat syscalls on arm64. These symbols were never shipped since arm64 exists only on 11+. Submitted by: brooks Reviewed by: emaste, imp 2016-04-06 16:09:10 +00:00			`MIASM:= ${MIASM:Nfreebsd[467]_*}`

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.

Remove brk and sbrk from arm64. They were defined in The Single UNIX Specification, Version 2, but marked as legacy, and have been removed from later specifications. After 12 years it is time to remove them from new architectures when the main use for sbrk is an invalid method to attempt to find how much memory has been allocated from malloc. There are a few places in the tree that still call sbrk, however they are not used on arm64. They will need to be fixed to cross build from arm64, but these will be fixed in a follow up commit. Old copies of binutils from ports called into sbrk, however this has been fixed around 6 weeks ago. It is advised to update binutils on arm64 before installing a world that includes this change.

Reduce duplicate NOASM and PSEUDO definitions The initial value of NOASM is nearly the same in all cases and the initial value of PSEUDO is the same in all cases so reduce duplication (and hopefully, future merge conflicts) by machine independent defaults. Also document the PSEUDO variable.
