1a8ba8658c Initialize pmap->pm_active and pmap->pm_onproc. 
Avoid "panic: kernel diagnostic assertion "!pmap_tlb_intersecting_onproc_p(pm, ti)" failed: file "/usr/src/sys/uvm/pmap/pmap_tlb.c", line 762".

6d40f9ff57 add a new "fo_mmap" fileops method to allow use of arbitrary uvm_objects for 
mappings of file objects.  move vnode-specific details of mmap()ing a vnode
from uvm_mmap() to the new vnode-specific vn_mmap().  add new uvm_mmap_dev()
and uvm_mmap_anon() convenience functions for mapping character devices
and anonymous memory, and replace all other calls to uvm_mmap() with those.
use the new fileop in drm2 so that libdrm can use mmap() to map things
like on other platforms (instead of the ioctl that we have used so far).

f9228f4225 Add d_discard to all struct cdevsw instances I could find. 
All have been set to "nodiscard"; some should get a real implementation.

8c70ef39af Add d_discard to all struct bdevsw instances I could find. 
I've set them all to nodiscard. Some of them (wd, dk, vnd, ld,
raidframe, maybe cgd) should be implemented for real.

9aaf8e57e5 Split out the minherit code into separate functions for readability (allows 
us to indent them properly), and merge the new vm_map_entry creation into
a common function to avoid code duplication. No functional change.

87145c7a28 This KASSERT can trigger a panic too easily, if SCARG(uap, cmd)=SWAP_OFF and 
SCARG(uap, arg)=NULL. The same KASSERT is already in the SWAP_ON switch case,
so just delete it here.

1627c0ae4a Allow this to handle H/W tlbs. Some ARM allow for a cheap way to flush all 
entries using an ASID from the TLB.  Add support for taking advantage of it.
Most ARMs don't have an easy way to find out what's in the TLB so make
record_asids can just say all ASIDs are in use.  Fix some off by 1 errors.

a68f9396b6 Change (mostly mechanically) every cdevsw/bdevsw I can find to use 
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
