02ae558db8 - removed old unused code designed for a save/restore feature 
- fixed pcidev targets in iodev/Makefile.in
- updated all Makefile dependencies using a default setup (.conf.linux).
  TODO: dependencies should be generated at compile time since they depend on
  the config settings

69c0b06955 fixes in disassembler 
split REPEAT instructions according to opsize to speedup execution
now each REPEATABLE instruction splitted to 3 different instructions, one for 16-bit operand size, one for 32-bit and one for 64-bit. Choosing of correct instruction occure in fetchdecode step.

Stanislav Shwartsman
645e04860e For now : disable fetching from physical address 0xFFFFFFF0 after #RESET 
because ICACHE do not support physical address > mem.len.
This is the first part of the fix, the rest coming soon

f06c8b6b95 EIP > CS.limit should not be a problem 
Manual says that GP(0) shouldd be generated in this case ALWAYS
Fixed instructions PANIC messages to ERROR for this case
And ... do not leave PANIC messages w/o taking care that user could push CONTINUE button and program should know to continue after the PANIC code line. Mainly in rerurn instructions were several problems ...
