pass memory for vmem structs into the initialization functions and
do away with the static pools for this.
factor out the vmem internal structures into a private header.
remove special bootstrapping of the kmem_va_arena as all necessary memory
comes from pool_allocator_meta wich is fully operational at this point.
- Fix an old bug of possible lock against oneself (uao_detach_locked() is
called from uao_swap_off() with uao_list_lock acquired). Also removes
the try-lock dance in uao_swap_off(), since the lock order changes.
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
thanks for tracking this down to everyone involved
caches, merge together pool_drain_start() and pool_drain_end() into
bool pool_drain(struct pool **ppp);
"bool" value indicates whether reclaiming was fully done (true) or not (false)
"ppp" will contain a pointer to the pool that was drained (optional).

passed to sysctl_createv() actually matches the declared type for
the item itself.
In the places where the caller specifies a function and a structure
address (typically the 'softc') an explicit (void *) cast is now needed.
Fixes bugs in sys/dev/acpi/asus_acpi.c sys/dev/bluetooth/bcsp.c
sys/kern/vfs_bio.c sys/miscfs/syncfs/sync_subr.c and setting
AcpiGbl_EnableAmlDebugObject.
(mostly passing the address of a uint64_t when typed as CTLTYPE_INT).
I've test built quite a few kernels, but there may be some unfixed MD
fallout. Most likely passing &char[] to char *.
Also add CTLFLAG_UNSIGNED for unsiged decimals - not set yet.
context is not valid on other types.
Prevents the crash reported in PR kern/38889, but does not fix the
mmap of block devices, more work is needed (no size on VBLK vnodes).
translate FSYNC_LAZY into PGO_LAZY for VOP_PUTPAGES() so that
genfs_do_io() can set the appropriate io priority for the I/O.
this is the first part of addressing PR 46325.
- always provide a vmspace for the new proc, initially borrowing from proc0
(this part fixes PR 46286)
- increase parallelism between parent and child if arguments allow this,
avoiding a potential deadlock on exec_lock
- add a new flag for userland to request old (lockstepped) behaviour for
better error reporting
- adapt test cases to the previous two and add a new variant to test the
diagnostics flag
- fix a few memory (and lock) leaks
- provide netbsd32 compat
(do not trucate it to the first __PGRM_BATCH pages per batch): if we were
given a sparse mapping, we could leave mappings in place.
Note that this doesn't seem to be a problem right now: I added a KASSERT
in my private tree to see if uvm_km_pgremove_intrsafe() would use a
too short size, and it didn't fire.
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).
