0ed36875f4 Ensure GCC does not use FP registers in integer code.
I think all we really need is -fno-sse2.
I really don't like cluttering up the compiler invocation,
but this bigger hammer will fix reported problems for now.

721d5bfe2e Allow kernels loaded by pxeboot, which was compiled with LOADER_TFTP_SUPPORT,
to stll be able to mount NFS root as prescribed by DCHP configuration. Since
pxeboot is using TFTP to get to the files, pxeboot can not rely on NFS to
provide it a root directory hande as a side effect. pxeboot has to  make RPC
mount call itself.

4e38f13b5b - If the COMSPEED is set to 0, then don't try to initialize the serial port
and assume that the BIOS has set it up for us.  This allows folks with a
  serial-aware BIOS to set the BIOS to speeds above 9600 and allow boot0 to
  just use the existing settings.
- Purge some gratuitous cpp comments as per style(9).

ca9b2364c3 A long, long time ago in a CVS branch far away (specifically, HEAD prior
to 4.0 and RELENG_3), the BTX mini-kernel used paging rather than flat
mode and clients were limited to a virtual address space of 16 megabytes.
Because of this limitation, boot2 silently masked all physical addresses
in any binaries it loaded so that they were always loaded into the first
16 Meg.  Since BTX no longer has this limitation (and hasn't for a long
time), remove the masking from boot2.  This allows boot2 to load kernels
larger than about 12 to 14 meg (12 for non-PAE, 14 for PAE).

941fdb393b Add the loader side of support for preloading ELF relocatable object
format modules, which are currently only used on the amd64 platform.
This initial implementation just parses enough of the module to
allow it to extract dependencies and load all the bits into the
right place in memory, so the kernel must still do the full relocation
and linking. The details of the loaded sections are passed to the
kernel by supplying a copy of the ELF section header table as module
metadata with the MODINFOMD_SHDR tag.

a30e1135b4 Don't be too smart, just try packet mode of INT13 first.
This way of operation is more robust than the "AI" used
before.

Add flags to mbr accessible from make.conf as BOOT_MBR_FLAGS.
Only one flag is defined now, "allow using packet mode", which
is 0x80 in accord with the rest of i386 boot code.  The "packet"
flag is on by default.

57888b4c83 Try packet mode of INT13 on a hard disk first if not prohibited by
the flag, fall back to the old INT13/AH=02 function if that fails.
This way of operation is less likely to fail with modern BIOSes and
large disks of strange geometries.

edfa817773 After talking to Bruce Evans and reading more standards specs,
switch to using C99-style comments everywhere in preprocessed
assembler.  The reason is that lines starting with the regexp
'^[[:space:]]#' are treated as preprocessing directives, and
while it seems to work now with GCC, it's not necessarily has
to work.  Use C99 comments `//' for the trailing comments to
save whitespace.
