d93fe1fd9b The MSR EFER state is not saved and restored when sleeping on i386. On PAE, 
the CPU crashes right after waking up, since it needs to access NOX-ed
pages, which are to be enabled in an MSR.

Fix this by properly saving and restoring the EFER MSR. It's a little
tricky since the wakeup code uses %edx, but rdmsr overwrites it. We just
save it in %esi.

Now, the CPU sleeps properly on PAE kernels.

a5229b934a Cause rc to abort if mounting any of the critical local filesystems fails 
rather than just ignoring the error.

Don't bother attempting to clear the contents of /var/run if /var/run
does not exist.

In that case the mkdir of /var/run/lvm would have failed - correct that
by using mkdir -p (which as a side effect will ensure /var/run exists
and is available for later scripts to use if for some reason it did not exist.)

96f7f6331a When mapping a dmamem page, make sure to trunc_pae the starting address 2016-07-22 19:50:44 +00:00

09c0f3ded7 Remove pmap_prealloc_lowmem_ptps on amd64. This function creates levels in 
the page tree so that the first 2MB of virtual memory can be kentered in
L1.

Strictly speaking, the kernel should never kenter a virtual page below
VM_MIN_KERNEL_ADDRESS, because then it wouldn't be available in userland.
It used to need the first 2MB in order to map the CPU trampoline and the
initial VAs used by the bootstrap code. Now, the CPU trampoline VA is
allocated with uvm_km_alloc and the VAs used by the bootstrap code are
allocated with pmap_bootstrap_valloc, and in either case the resulting VA
is above VM_MIN_KERNEL_ADDRESS.

The low levels in the page tree are therefore unused. By removing this
function, we are making sure no one will be tempted to map an area below
VM_MIN_KERNEL_ADDRESS in kernel mode, and particularly, we are making sure
NULL cannot be kentered.

In short, there is no way to map NULL in kernel mode anymore.

ef38d1c0f4 Reduce KERNEL_LOCK thereby ifq_lock is used by default. 
if_snd is always excluded by ifq_lock now. So, the KERNEL_LOCK in if_transmit()
which serializes packet output processing is not needed now.

b14a26cee3 Toward NET_MPSAFE-on in future, if_snd uses if_snd->ifq_lock by default. 
That can reduce confusing difference between NET_MPSAFE on and off.
