3c5b0fdd52 dart: Add DART_PTR_ERR to indicate failures for IOVA returning functions 
0 is a valid and used device virtual address. Daart functions returning
device address can not use 0 to indicate errors.

da9ceddeac memory: Map lowmem using 16K pages only 
Turns out CTRR does not like working with huge pages, and just throws up
its hands in the air with an L2 address size fault if a huge page
overlaps the CTRR region.

6feceef2b0 hv_vm: Retry mapped page faults

ad29c08ab8 exception: Clear L2C error flags on exception

don't do this, then the SError behaves as level-triggered and just continues
to fire.

0c04783a86 main: Check for SIP disable for proxy backdoor mode 
Seems -v stopped being filtered (or never was?). Explicitly check boot
policy, so we don't depend on boot-args filtering directly (which can
change). -v still makes things verbose unconditionally, but the proxy
backdoor now requires that plus full SIP disable (sip0=127).
