    dma: make dma access its own address space
    
    Instead of accessing the cpu address space, use an address space
    configured by the caller.
    
    Eventually all dma functionality will be folded into AddressSpace,
    but we have to start from something.

Title:
  QNX 4 doesn't boot on qemu >= 1.3

Status in QEMU:
  New

Bug description:
  
  I am using virtual machine with QNX4 operating system installed on it.  I 
updated my qemu from version
  to newer and QNX4 doesn't start any more. All is ok on version 1.2 but when I 
try to use any newer version 
  (1.3, 1.4, 1.5)  QNX4 doesn't boot.  I tried on windows and linux ubuntu 
hosts - effects are the same.

  When virtual machine boots qnx bootloader loads and starts operating system. 
In the next step
  qnx starts its ide driver, which detects qemu harddisk and cdrom. Problem 
starts when operating system
  tries mount partition - an error occur and qnx stop booting procedure:

  mount -p "No bios signature in partition sector on /dev/hd0"

  I have tried install qnx from cdrom but it seems that there is the same 
problem. QNX installer boot from
  cdrom, detects hard disk and cdrom, but cdrom can't be mounted in the next 
step of installation procedure.
