d07160f401 Change the disk probing so that it will actually find disks other
than the first one on a controller, and work for secondary
controllers.
Due to the prom not having nodes for each disk, but a catch-all one,
we have to iterate over each device, trying to open it to determine
whether it is actually present.
Since probing this way takese some time (and spews some spurious
warnings), it should maybe be short-circuited if we use the
device we were booted from.
Implement lazy device probing, and correct slice/partiniton
handling in the ofwd_open() code. With this, I can now actually boot
a kernel from disk, and the loader does not create unnecessary
delays.

88f0d73da4 - Axe -mpreferred-stack-boundary=2 as -Os turns this on by default.
- Axe -fdata-sections as turning it on or off makes no difference.  If
  it did make a difference it would serve to bloat boot2 even further with
  extra padding.
- Axe -fforce-addr.  This gets us 32 bytes so we are down to only being
  64-bytes over.

We still can't compile this with gcc 3.1.  The problem seems to be that
the -fno-align-foo options don't actually work.  Comparing the new and
old output it turns out that gcc is 4-byte padding all the functions and
labels and what not despite the passed in arguments thus adding the
unfortunate bloat to boot2.

1a923a14f4 A long, long time ago, msmith introduced vfs.root.mountfrom
loader variable, which let users specify the root mount point
the exact way one does after booting the kernel.

Let's take this opportunity to document it...

1de372dcd4 Add a -k option to reboot to specify the kernel to boot next time
around.  If the kernel boots successfully, the record of this kernel
is erased, it is intended to be a one-shot option for testing
kernels.

This could be improved by having the loader remove the record of
the next kernel to boot, it is currently removed in /etc/rc immediately
after disks are mounted r/w.

I'd like to MFC this before the 4.6 freeze unless there is violent
objection.

77de753f65 Improve self-relocation:
o  We don't expect the PLT relocations to follow the .rela section
   anymore. We still assume that PLT relocations are long formed,
o  Document register usage,
o  Improve ILP,
o  Fix the FPTR relocation by creating unique OPDs per function.
   Comparing functions is valid now,
o  The IPLT relocation naturally handles the addend. Deal with it.
   We ignore the addend for FPTR relocations for now. It's not at
   all clear what it means anyway.

Fix ABI misinterpretation:
o  For Elf_Rela relocations, the addend is explicit and should not
   be loaded from the memory address we're relocating. Only do that
   for Elf_Rel relocations (ie the short form).
o  DIR64LSB is not the same as REL64LSB. DIR64LSB applies to a
   symbol (S+A), whereas REL64LSB applies to the base address (BD+A),

31c41f1b1e Bandaid for a buffer overrun in the module searching code. When breaking
up the module_path string, we would walk one past the end of the buffer.
This hurting ia64 originally, but it was probably also happening on i386
occasionally as well.  The effects were usually harmless, it would add
bogus "binary" search directories to the places it actually looked for
files.

2ab188f529 Finally fix loader completely for IA64. efifs_stat() wasn't setting
the S_IFREG bit for regular files.  This caused the path search code to
skip it when it finally did find the kernel (after the common/module.c
buffer overrun bug was fixed)

a6d81d83a2 Fix self hosted loader building. When you use a self configured gcc, it
detects and uses the gas section merge support.  As a result, a whole bunch
of new sections arrive, including .rodata.str1.8, which was not included
in our custom ldscript.ia64.  The result was a loader binary that EFI
rejected.

While here, collect the loader shell commands linker set and include it
in the data area rather than having its own section.

/boot/loader.efi was the last holdout for having a 100% self built ia64
system.
