64311e1f9d Introduce a couple of new constants, VMEM_ADDR_MIN (the least possible 
address in a vmem(9) arena, 0) and VMEM_ADDR_MAX (the maximum possible
address, currently 0xFFFFFFFF).  Modify several boundary conditions so
that a vmem(9) arena can allocate ranges including VMEM_ADDR_MAX.
Update documentation and tests.

These changes pass the tests in sys/kern/subr_vmem.c.  To compile the
and run the test program, run "cd sys/kern/ && gcc -DVMEM_SANITY -o
subr_vmem ./subr_vmem.c && ./subr_vmem".

1beaa2ceec PR/45285: Martin Matuska: makefs does not properly convert ISO level 1 and 2 
filenames (buffer overflow)

makefs does not properly verify the maximum filename length in the
special "." case for both ISO level 1 and ISO level 2 filename
conversion.  This creates broken images or causes a buffer overflow
(ISO level 2).

ISO level 1:
If a filename contains only dots or up to 8 characters followed by
dots the 8+3 limit check doesn't work.

ISO level 2:
If a filename contains a dot in the first 30 characters and a dot
on the 30th character, the length limit check doesn't work and the
buffer is overflowed.

$ mkdir level1
$ touch level1/12345............
$ makefs -t cd9660 -o isolevel=1 test.iso level1

$ mkdir level2
$ touch level2/1234567890.2345678901234567.....34567890123456789012345
$ makefs -t cd9660 -o isolevel=2 test.iso level2

28ab15e044 don't use lwp_setprivate in fork, but copy the private lwp member directly 
because userland might have messed with the TLS register without letting
the kernel know. This fixes fork() on amd64. Thanks chuq!

69a4e2ee5b PR/45269: Andreas Gustafsson: Instead of falling off the edge when eating trailing newlines 
if the block has moved, arrange so that trailing newlines are never placed in the string
in the first place, by accumulating them and adding them only after we've encountered a
non-newline character. This allows also for more efficient appending since we know how much
we need beforehand. From FreeBSD.

f937bd97b7 Stop abusing relookup() to prepare the creation of new nodes

Replace union_relookup() with union_do_lookup() that prepares
a component, calls VOP_LOOKUP() and does the EEXIST test.
