c4c3b35172 Add new loader console type: "spinconsole". This console selects the
video console which doesn't take any input from keyboard and hides
all output replacing it with ``spinning'' character (useful for
embedded products and custom installations).

cc4757ddef Some of the boot loader code only works on a ufs file system, but it
uses the generic struct dirent, which happens to look identical to UFS's
struct direct.  If BSD ever changes dirent then this will be a problem.

c22616ec0b - Initialize the vm86 structure to a known-good state. Specifically, always
set the %eflags used during a BIOS call via BTX to 0x202.  Previously
  the flags field was uninitialized garbage, and thus it was "random" if
  interrupts were enabled or not during BIOS calls.
- Use constants from <machine/psl.h> for fields in %eflags.

cae17430bf Fix a fallout from SSP commit, and make this compile again.
Bonus: including kern.mk just to pick kernel warning flags
was an extremely bad idea anyway, because it also picked
up CFLAGS (it probably wasn't the case at the time of CVS
rev. 1.1, I haven't checked).  Remove duplicate CWARNFLAGS
from CFLAGS.

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

f2a081cfe4 Added the IPLware 3.33 support.
- Added magic numbers to pretend the NEC original program version
    2.70.
  - Added string display routine with Shift-JIS code support.
  - Added three nop instructions at start1 in start.s since the
    installaer of the IPLware put 'call $0x09ab' instruction.
  - Put the near return instruction at 0x9ab in selector.s.

Since the Shit-JIS display routine must be located at 0x1243, the
linker script file (ldscript) is applied.

593bbd2195 Revert the last change. Masking only 2 MSBs of the virtual address
to get the physical address doesn't work for all values of KVA_PAGES,
while masking 8 MSBs works for all values of KVA_PAGES that are
multiple of 4 for non-PAE and 8 for PAE.  (This leaves us limited
with 12MB for non-PAE kernels and 14MB for PAE kernels.)

To get things right, we'd need to subtract the KERNBASE from the
virtual address (but KERNBASE is not easy to figure out from here),
or have physical addresses set properly in the ELF headers.

932d8c46a2 Extend struct devdesc with a unit field, called d_unit. Promote the
device (kind) specific unit field to the common field. This change
allows a future version of libefi to work without requiring anything
more than what is defined in struct devdesc and as such makes it
possible to compile said version of libefi for different platforms
without requiring that those platforms have identical derivatives
of struct devdesc.

da6d4298b7 Because the BTX mini-kernel now uses flat memory mode and clients
are no longer limited to a virtual address space of 16 megabytes,
only mask high two bits of a virtual address.  This allows to load
larger kernels (up to 1 gigabyte).  Not masking addresses at all
was a bad idea on machines with less than >3G of memory -- kernels
are linked at 0xc0xxxxxx, and that would attempt to load a kernel
at above 3G.  By masking only two highest bits we stay within the
safe limits while still allowing to boot larger kernels.

(This is a safer reimplmentation of sys/boot/i386/boot2/boot.2.c
rev. 1.71.)
