PR kern/58425 -- Disallow INT_MIN as a (negative) pid arg.

Since -INT_MIN is undefined, and to point of negative pid args is
to negate them, and use the result as a pgrp id instead, we need
to avoid accidentally negating INT_MIN.

Since pid_t is just an integral type, of unspecified width, when
testing pid_t value test for <= INT_MIN (or > INT_MIN sometimes)
rather than == INT_MIN. When testing int values, just == INT_MIN
is all that is needed, < INT_MIN cannot occur.

Fix a bug where the kernel was never grown to accomodate the kmem VA space
since that happens before the kernel_map is set.
Don't try grow the entire kmem space but just do as needed in
uvm_km_kmem_alloc
Shut up gcc printf warning.
Cleanup comment. Change panic to KASSERTMSG.
Use kernel_map->misc_lock to make sure we don't call pmap_growkernel
concurrently and possibly mess up uvm_maxkaddr.
Switch to a spin lock (uvm_kentry_lock) which, fortunately, was
sitting there
unused.
Remove locking since it isn't needed. As soon as the 2nd
uvm_map_entry in kernel_map
is created, uvm_map_prepare will call pmap_growkernel and the
pmap_growkernel call in
uvm_km_mem_alloc will never be called again.
call pmap_growkernel once after the kmem_arena is created
to make the pmap cover it's address space
assert on the growth in uvm_km_kmem_alloc
for the 3rd uvm_map_entry uvm_map_prepare will grow the kernel,
but we might call into uvm_km_kmem_alloc through imports to
the kmem_meta_arena earlier
while here guard uvm_km_va_starved_p from kmem_arena not yet created

Apply patch proposed in PR port-xen/45975 (this does not solve the exact
problem reported here but is part of the solution):
xen_kpm_sync() is not working as expected,
leading to races between CPUs.
1 the check (xpq_cpu != &x86_curcpu) is always false because we
have different x86_curcpu symbols with different addresses in the kernel.
Fortunably, all addresses dissaemble to the same code.
Because of this we always use the code intended for bootstrap, which doesn't
use cross-calls or lock.
2 once 1 above is fixed, xen_kpm_sync() will use xcalls to sync other CPUs,
which cause it to sleep and pmap.c doesn't like that. It triggers this
KASSERT() in pmap_unmap_ptes():
KASSERT(pmap->pm_ncsw == curlwp->l_ncsw);
3 pmap->pm_cpus is not safe for the purpose of xen_kpm_sync(), which
needs to know on which CPU a pmap is loaded *now*:
pmap->pm_cpus is cleared before cpu_load_pmap() is called to switch
to a new pmap, leaving a window where a pmap is still in a CPU's
ci_kpm_pdir but not in pm_cpus. As a virtual CPU may be preempted
by the hypervisor at any time, it can be large enough to let another
CPU free the PTP and reuse it as a normal page.
To fix 2), avoid cross-calls and IPIs completely, and instead
use a mutex to update all CPU's ci_kpm_pdir from the local CPU.
It's safe because we just need to update the table page, a tlbflush IPI will
happen later. As a side effect, we don't need a different code for bootstrap,
fixing 1). The mutex added to struct cpu needs a small headers reorganisation.
to fix 3), introduce a pm_xen_ptp_cpus which is updated from
cpu_pmap_load(), whith the ci_kpm_mtx mutex held. Checking it with
ci_kpm_mtx held will avoid overwriting the wrong pmap's ci_kpm_pdir.
While there I removed the unused pmap_is_active() function;
and added some more details to DIAGNOSTIC panics.
When using uvm_km_pgremove_intrsafe() make sure mappings are removed
before returning the pages to the free pool. Otherwise, under Xen,
a page which still has a writable mapping could be allocated for
a PDP by another CPU and the hypervisor would refuse it (this is
PR port-xen/45975).
For this, move the pmap_kremove() calls inside uvm_km_pgremove_intrsafe(),
and do pmap_kremove()/uvm_pagefree() in batch of (at most) 16 entries
(as suggested by Chuck Silvers on tech-kern@, see also
http://mail-index.netbsd.org/tech-kern/2012/02/17/msg012727.html and
followups).
Avoid early use of xen_kpm_sync(); locks are not available at this time.
Don't call cpu_init() twice.
Makes LOCKDEBUG kernels boot again
Revert pmap_pte_flush() -> xpq_flush_queue() in previous.
