7959685201 as: add deprecation notice to the man page
In the future FreeBSD will ship without GNU binutils 2.17.50.  Add a
note advising users who require GNU as to install the binutils port
or package.

Note that on armv7, arm64, amd64, i386 we currently ship only two
binutils tools (as and objdump).  A deprecation notice was added to
objdump's man page some time ago.

e861dab451 powerpc: Transition to Secure-PLT, like most other OSs (Toolchain part)
Summary:
Toolchain follow-up to r349350.  LLVM patches will be submitted upstream for
9.0 as well.

The bsd.cpu.mk change is required because GNU ld assumes BSS-PLT if it
cannot determine for certain that it needs Secure-PLT, and some binaries do
not compile in such a way to make it know to use Secure-PLT.

5d031e332f Create crtsavres.o for powerpc builds
Summary:
GCC expects to link in a crtsavres.o on powerpc platforms.  On
powerpc64 this is an empty file, but on powerpc and powerpcspe this does contain
some save/restore functions, which may not actually be necessary for newer
modern GCC and clang.  This appeases the in-tree gcc, though, and is needed in
order to switch to the BSD CRTRBEGIN.

104f6a2dcd Fix GCC 4.2.1 to honor --sysroot for includes.
- Change the C++ directory entries to honor --sysroot if it is set.
- Don't define CROSS_INCLUDE_DIR for the cross compiler.  Instead, set
  TARGET_SYSTEM_ROOT to point to WORLDTMP and always define
  STANDARD_INCLUDE_DIR.
- Change STANDARD_INCLUDE_DIR and the C++ include directories to just
  start with "/usr" always.  The compiler will prepend the sysroot when
  doing cross-builds.  GCC_INCLUDE_DIR (which contains headers that ship
  with the compiler such as intrinsincs rather than OS-supplied headers)
  remains hardcoded to look in TOOLS_PREFIX.

d86c1f0dc1 i386 4/4G split.
The change makes the user and kernel address spaces on i386
independent, giving each almost the full 4G of usable virtual addresses
except for one PDE at top used for trampoline and per-CPU trampoline
stacks, and system structures that must be always mapped, namely IDT,
GDT, common TSS and LDT, and process-private TSS and LDT if allocated.

By using 1:1 mapping for the kernel text and data, it appeared
possible to eliminate assembler part of the locore.S which bootstraps
initial page table and KPTmap.  The code is rewritten in C and moved
into the pmap_cold(). The comment in vmparam.h explains the KVA
layout.

There is no PCID mechanism available in protected mode, so each
kernel/user switch forth and back completely flushes the TLB, except
for the trampoline PTD region. The TLB invalidations for userspace
becomes trivial, because IPI handlers switch page tables. On the other
hand, context switches no longer need to reload %cr3.

copyout(9) was rewritten to use vm_fault_quick_hold().  An issue for
new copyout(9) is compatibility with wiring user buffers around sysctl
handlers. This explains two kind of locks for copyout ptes and
accounting of the vslock() calls.  The vm_fault_quick_hold() AKA slow
path, is only tried after the 'fast path' failed, which temporary
changes mapping to the userspace and copies the data to/from small
per-cpu buffer in the trampoline.  If a page fault occurs during the
copy, it is short-circuit by exception.s to not even reach C code.

The change was motivated by the need to implement the Meltdown
mitigation, but instead of KPTI the full split is done.  The i386
architecture already shows the sizing problems, in particular, it is
impossible to link clang and lld with debugging.  I expect that the
issues due to the virtual address space limits would only exaggerate
and the split gives more liveness to the platform.
