23eeeff7be Split 4.x and 5.x signal handling so that we can keep 4.x signal
handling clean and functional as 5.x evolves.  This allows some of the
nasty bandaids in the 5.x codepaths to be unwound.

Encapsulate 4.x signal handling under COMPAT_FREEBSD4 (there is an
anti-foot-shooting measure in place, 5.x folks need this for a while) and
finish encapsulating the older stuff under COMPAT_43.  Since the ancient
stuff is required on alpha (longjmp(3) passes a 'struct osigcontext *'
to the current sigreturn(2), instead of the 'ucontext_t *' that sigreturn
is supposed to take), add a compile time check to prevent foot shooting
there too.  Add uniform COMPAT_43 stubs for ia64/sparc64/powerpc.

Tested on: i386, alpha, ia64.  Compiled on sparc64 (a few days ago).

fb3a308a4a Change method to determine base memory size.
Try INT 15H/E820H first, then fall back to the old compatibility
method (INT 12H).
This is a workaround for newer machines which have broken INT 12H BIOS
service implementation.

df6b615a42 #include <geom/geom.h> to get proper prototypes. Contrary to my fears we
seem to have all the prerequisites already.

Call g_waitidle() as the first thing in vfs_mountroot() so that we have
it out of the way before we even decide if we should call .._ask() or
.._try().

Call the g_dev_print() function to provide better guidance for the
root-mount prompt.

736b63df0d Fix iommu_dvmamap_sync() to use the right address when flushing the
streaming cache. This bug could have the potential to cause data
corruption on systems with Psycho U2P bridges (Sabre bridges have no
streaming cache).
However, due to the usual driver architecture, it is believed that
corruption did occur only in rare cases (if at all).

d793791855 Use the correct values for LDBL_*. Libc doesn't completely support
long doubles at the moment (printf truncates them to doubles).
However, long doubles to appear to work to the ranges listed in this
commit on both -stable (4.5) and -current.  There may be some slight
rounding issues with long doubles, but that's an orthogonal issue to
these constants.

I've had this in my local tree for 3 months, and in my company's local
tree for 15 months with no ill effects.

9ab73fd11a Within ufs, the ffs_sync and ffs_fsync functions did not always
check for and/or report I/O errors. The result is that a VFS_SYNC
or VOP_FSYNC called with MNT_WAIT could loop infinitely on ufs in
the presence of a hard error writing a disk sector or in a filesystem
full condition. This patch ensures that I/O errors will always be
checked and returned.  This patch also ensures that every call to
VFS_SYNC or VOP_FSYNC with MNT_WAIT set checks for and takes
appropriate action when an error is returned.
