| Refresh bug reported by Julien Torres:

| going from:
|     activate -verbose
| to:
|     reset -activation
| results in:
|     reset -activationverbose"
| instead of:
|     reset -activation
|
| This is because we choose to insert "reset -" before the current line,
| and the delete "e -" and insert "ion" in the appropriate place. The
| cleareol code did not handle this case properly; we now cleareol to
| the maximum number of characters of the first difference, the second
| difference and the difference in line length.

669152498a Use the usual volatile hack to trick gcc into clipping any extra precision
on assignment.

Extra precision on i386's broke hi+lo decomposition in the usual way.
It caused all except 1 of the 62343 errors of more than 1 ulp for
log1pf() on i386's with gcc -O [-fno-float-store].

58299dd09e - Move the declaration of struct upa_ranges and the UPA_RANGE_* macros
from sys/sparc64/include/ofw_upa.h to sys/sparc64/pci/ofw_pci.h and
  rename them to struct ofw_pci_ranges and OFW_PCI_RANGE_* respectively.
  This ranges struct only applies to host-PCI bridges but no to other
  bridges found on UPA. At the same time it applies to all host-PCI
  bridges regardless of whether the interconnection bus is Fireplane/
  Safari, JBus or UPA.
- While here rename the PCI_CS_* macros in sys/sparc64/pci/ofw_pci.h
  to OFW_PCI_CS_* in order to be consistent and change this header to
  use uintXX_t instead of u_intXX_t.

3a721a33cf - Register the PCI bus error interrupt handler according to which half of
the bridge (PCI bus A or B) we are attaching to rather than registering
  both handlers at once when attaching to the first half we encounter.
  This is a bit cleaner as it corresponds to which PCI bus error interrupt
  actually is assigned to the respective half by the OFW and allows to
  collapse both PCI bus error interrupt handlers into one function easily.
- Use the actual RID of the respective interrupt resource as index into
  sc_irq_res and also use it when allocating the resource. For now this
  is a bit cleaner and will be mandatory later on.
- According to OpenSolaris the spare hardware interrupt is used as the
  over-temperature interrupt in systems with Psycho bridges. Unlike as
  with the SBus-based workstations I didn't manage to trigger it when
  covering the fan outlets of an U60 but better be safe than sorry and
  register a handler anyway.

It was lost in rev.1.9.  The log message for rev.1.9 says that the
special case of +-0 is handled twice, but it was only handled once,
so it became unhandled, and this happened to break half of the cases
that return +-0:
- round-towards-minus-infinity:  0   <  x < 1:  result was -0 not  0
- round-to-nearest:             -0.5 <= x < 0:  result was  0 not -0
- round-towards-plus-infinity:  -1   <  x < 0:  result was  0 not -0
- round-towards-zero:           -1   <  x < 0:  result was  0 not -0

3fc5a433e9 Simplified the fix in rev.1.3. Instead of using long double for
TWO52[sx] to trick gcc into correctly converting TWO52[sx]+x to double
on assignment to "double w", force a correct assignment by assigning
to *(double *)&w.  This is cleaner and avoids the double rounding
problem on machines that evaluate double expressions in double
precision.  It is not necessary to convert w-TWO52[sx] to double
precision on return as implied in the comment in rev.1.3, since
the difference is exact.

7441377544 Fixed rint(x) in the following cases:
(1) In round-to-nearest mode, on all machines, fdlibm rint() never
    worked for |x| = n+0.75 where n is an even integer between 262144
    and 524286 inclusive (2*131072 cases).  To avoid double rounding
    on some machines, we begin by adjusting x to a value with the 0.25
    bit not set, essentially by moving the 0.25 bit to a lower bit
    where it works well enough as a guard, but we botched the adjustment
    when log2(|x|) == 18 (2*2**52 cases) and ended up just clearing
    the 0.25 bit then.  Most subcases still worked accidentally since
    another lower bit serves as a guard.  The case of odd n worked
    accidentally because the rounding goes the right way then.  However,
    for even n, after mangling n+0.75 to 0.5, rounding gives n but the
    correct result is n+1.
(2) In round-towards-minus-infinity mode, on all machines, fdlibm rint()
    never for x = n+0.25 where n is any integer between -524287 and
    -262144 inclusive (262144 cases).  In these cases, after mangling
    n+0.25 to n, rounding gives n but the correct result is n-1.
(3) In round-towards-plus-infinity mode, on all machines, fdlibm rint()
    never for x = n+0.25 where n is any integer between 262144 and
    524287 inclusive (262144 cases).  In these cases, after mangling
    n+0.25 to n, rounding gives n but the correct result is n+1.

A variant of this bug was fixed for the float case in rev.1.9 of s_rintf.c,
but the analysis there is incomplete (it only mentions (1)) and the fix
is buggy.

Example of the problem with double rounding: rint(1.375) on a machine
which evaluates double expressions with just 1 bit of extra precision
and is in round-to-nearest mode.  We evaluate the result using
(double)(2**52 + 1.375) - 2**52.  Evaluating 2**52 + 1.375 in (53+1) bit
prcision gives 2**52 + 1.5 (first rounding).  (Second) rounding of this
to double gives 2**52 + 2.0.  Subtracting 2**52 from this gives 2.0 but
we want 1.0.  Evaluating 2**52 + 1.375 in double precision would have
given the desired intermediate result of 2**52 + 1.0.

The double rounding problem is relatively rare, so the botched adjustment
can be fixed for most machines by removing the entire adjustment.  This
would be a wrong fix (using it is 1 of the bugs in rev.1.9 of s_rintf.c)
since fdlibm is supposed to be generic, but it works in the following cases:
- on all machines that evaluate double expressions in double precision,
  provided either long double has the same precision as double (alpha,
  and i386's with precision forced to double) or my earlier fix to use
  a long double 2**52 is modified to avoid using long double precision.
- on all machines that evaluate double expressions in many more than 11
  bits of extra precision.  The 1 bit of extra precision in the example
  is the worst case.  With N bits of extra precision, it sufices to
  adjust the bit N bits below the 0.5 bit.  For N >= about 52 there is
  no such bit so the adjustment is both impossible and unnecessary.  The
  fix in rev.1.9 of s_rintf.c apparently depends on corresponding magic
  in float precision: on all supported machines N is either 0 or >= 24,
  so double rounding doesn't occur in practice.
- on all machines that don't use fdlibm rint*() (i386's).
So under FreeBSD, the double rounding problem only affects amd64 now, but
should only affect i386 in future (when double expressions are evaluated
in long double precision).

6affdd3055 "-o rw" is invalid and undocumented mount option that
is only present for fstab(5) compatibility, and is
otherwise ignored by mount(8) (not passed to mount_*
programs, and not passed to nmount(2)).

"-u -o rw" worked with an old mount(8) with mount_ufs.c
because "-o rw" was stripped and simple "-u" caused an
update of UFS from read-only to read-write, due to
inability of mount(2) to track changes in options
(MNT_RDONLY is either set or not).

"-u" no longer causes the transition from RO to RW,
now that mount(8) was converted to use nmount(2), so
an explicit change to RW is required.  Keep up with
this change, and use "-uw" to mount root read-write.
