make sure to properly account for the "lost" space during all calculations
and especially when expanding the main partition to fill the disk.
Avoid using the global "pm" or a passed device descriptons when we are
passing disk limits explicitly anyway.
Simplify/fix a few rounding calculations.
Rename the MM_REG macro to ST_MAN, to make it clearer that it gets
mantissa of ST registers which overlaps with MM registers but can be
also used to read ST registers (to be used in the next commit). Extend
it to cover the difference between GETFPREGS and GETXSTATE,
and therefore avoid additional condition on i386.

While here, change the example so it doesn't violate the advice just
given. Still not a great example -- abusing UINT_MAX for a reference
count is kinda sketchy, but it'll serve for now.
Passing a negative value to these legacy compat ioctls results in
left shift on a negative value which is undefined behaviour and results
in the tty (at least, possibly other things) locking up.
The argument to the ioctl should always be > 0. Return EINVAL otherwise.
While here, adjustments to code style to match current guidelines.

The valid sizes of the tty input and output queues (according to the man page)
are between 1024 and 65536 and input values are converted to a power of two.
The check on the validity of the range is done after the input values are
converted, however, which means that a hostile program can attempt to set
the queue size to a negative value, and cause integer overflow before
the range is validated.

Don't do link training or configuration space accesses within the time
allowed by the standard for the downstream card to come out of reset
after deasserting PERST#.
This fixes detection issues seen with a dual port wm(4) NIC,
an ASMedia SATA card and also Pericom bridges (but they need more work
to be useful).
This test still fails on FreeBSD, printing the "ar cru, ranlib" lines
twice, and I don't know why.
To get more insights into the inner details, without activating the full
-dA logging, split the output into paragraphs, one per target.
This change reveals another interesting detail: Dependencies without any
commands (in this case create-archive) don't inherit the commands from
.USEBEFORE and .USE sources.
Work around regression introduced in rev 1.92:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/kern/kern_cpu.c#rev1.92
by which ``cpuctl offline n'' became broken on architectures without
__HAVE_INTR_CONTROL (i.e., everything other than alpha and x86);
cpu_setintr() always fails on these archs, and we had neglected
return value from that function until rev 1.91.
XXX
As martin pointed out in the PR, I'm not sure whether fix in rev 1.92
itself is correct or not. Insert XXX comment referring the PR there....
(-O1 is fine). This is a new regression introduced in GCC9.
For everyone's safety, extend -O0 hack to dwarf2{expr,loc}.c for
all arm variants with GCC >= 8.

contiguous physical pages, and try this new allocator if the existing
one fails. The existing contig allocator only tries to allocate pages
that are already free, which works fine shortly after boot but rarely
works after the system has been up for a while. The new allocator uses
the pagedaemon to evict pages from memory in the hope that this will
free up a range of pages that satisfies the constraits of the request.
This should help with things like plugging in a USB device, which often
fails for some USB controllers because they can't get contigous memory.
GCC 9.3 seems to be able to compile rtree.c with -O2:
- No new regressions in ATF.
- System survives over a night, at least, under heavy loads.
On the other hand, unfortunately, GCC 9.3 still miscompiles tcache.c
with -O2 or -O1. For example, even ``gcc -g hello.c'' fails with ICE
if tcache.c is compiled with -O[12] in libc.
Link state transitions to UP when a node is joined and DOWN when left.
This means that with the interface UP, the link state could be UNKNOWN
for a while, implying it can be used in BSS mode.
Which is of course false.
Add a function to set an initial link state based on the operating mode.
Also call this when the operating mode changes.
Basically in BSS and MONITOR it starts off down.
BSS will transition UP and DOWN as before, MONITOR will stay down.
IBSS, AHDEMO and HOSTAP will remain as link unknown because the state is
..... unknown.
