Changeset 30338 in vbox for trunk/include

Timestamp:

Message:

EM,IOM: Don't try write directly to the fault address as the backing page might be read-only (shared page, write monitored page or zero page) and require special handle. Took the simple way out, which is to take the same path as in ring-0/3. Converted the remaining EMGCA.asm bits to EMAllA.asm code.
