e86256c1f4 o Move vm_freeze_copyopts() from vm_map.{c.h} to vm_object.{c,h}. It's plainly 
an operation on a vm_object and belongs in the latter place.

5eb6f4bc21 Restored db_elf.c from the Attic. This will be used for a quick fix for 
the longstanding brokenness of symbols in ddb at boot time.  It doesn't
compile and is not attached to the build yet.

576365ba36 Move a KASSERT() in open() prior to unlocking the vnode. It's not safe to 
call VOP_GETVOBJECT without a lock.

4e039937d9 Add a KERNELDUMPMAGIC_CLEARED macro to unbreak savecore. Since 
it is a "magic" value, what it expands to is not really important.
I set it to "Cleared Kernel Dump", but that can be changed later
if someone thinks it's not good enough.

f5216b9a19 Return the correct error code (ENOSYS, not EINVAL) from nosys(). Getting 
killed by SIGSYS for unimlemented syscalls is bad enough.

Obtained from:	Lite2 branch

The Lite2 branch has some other interesting unmerged (?) bits in this
file.  They are well hidden among cosmetic regressions.

a9a0f15a69 Fixed breakage of binary compatibility of the kern.clockrate sysctl in 
sys/time.h rev.1.53, etc.  Zero out the entire struct clkinfo and not
just the new spare part of it so that there is no possibility of leaking
kernel stack context to userland.

f318190a01 Fixed checking for VM86 mode in doreti which I broke in rev.1.30. Only 
the case of VM86 calls from the kernel was broken, so this bug was not
a security hole.

c7173f58fa Use pages instead of uz_maxpages, which has not been initialized yet, when

d9fc2b816e Do not call nge_tick() if we get an PHY interrupt, nge_tick() calls 
mii_tick() which should only be called once per second.

Our current MII/PHY state-engine is not able to deal with PHY
interrupts as far as I can tell, and most net drivers don't seem
to use the link/status change call-back mechanism.  It seems that
MII/PHY was orphaned before it grew up.

9a1bf46934 Make sure we don't index the pm_rid array out of bounds in 
pmap_ensure_rid(). This can happen because the function is
called for both user and kernel addresses, while the rid array
only has room for user addresses. This bug got exposed by rev
1.58 of ia64/ia64/pmap.c and rev 1.8 of ia64/include/pmap.h.
