Both Guest kernel and Guest Userspace execute in UM. The memory map is as follows:
Guest User address space:   0x00000000 -&gt; 0x40000000
Guest Kernel Unmapped:      0x40000000 -&gt; 0x60000000
Guest Kernel Mapped:        0x60000000 -&gt; 0x80000000
- Guest Usermode virtual memory is limited to 1GB.

Pull MIPS updates from Ralf Baechle:
 "The MIPS bits for 3.8.  This also includes a bunch fixes that were
  sitting in the linux-mips.org git tree for a long time.  This pull
  request contains updates to several OCTEON drivers and the board
  support code for BCM47XX, BCM63XX, XLP, XLR, XLS, lantiq, Loongson1B,
  updates to the SSB bus support, MIPS kexec code and adds support for
  kdump.

  When pulling this, there are two expected merge conflicts in
  include/linux/bcma/bcma_driver_chipcommon.h which are trivial to
  resolve, just remove the conflict markers and keep both alternatives."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (90 commits)
  MIPS: PMC-Sierra Yosemite: Remove support.
  VIDEO: Newport Fix console crashes
  MIPS: wrppmc: Fix build of PCI code.
  MIPS: IP22/IP28: Fix build of EISA code.
  MIPS: RB532: Fix build of prom code.
  MIPS: PowerTV: Fix build.
  MIPS: IP27: Correct fucked grammar in ops-bridge.c

  MIPS: Handle COP3 Unusable exception as COP1X for FP emulation
  MIPS: Fix poweroff failure when HOTPLUG_CPU configured.
  MIPS: MT: Fix build with CONFIG_UIDGID_STRICT_TYPE_CHECKS=y
  MIPS: Remove unused smvp.h
  MIPS/EDAC: Improve OCTEON EDAC support.
  MIPS: OCTEON: Add definitions for OCTEON memory contoller registers.
  MIPS: OCTEON: Add OCTEON family definitions to octeon-model.h

<title>fork: move the real prepare_to_copy() users to arch_dup_task_struct()</title>

Historical prepare_to_copy() is mostly a no-op, duplicated for majority of
the architectures and the rest following the x86 model of flushing the extended
register state like fpu there.

Remove it and use the arch_dup_task_struct() instead.

<title>MIPS: Make TASK_SIZE reflect proper size for both 32 and 64 bit processes.</title>

<id>949e51bea342da838be5295628e4a7ada8bae833</id>
<content type='text'>
The TASK_SIZE macro should reflect the size of a user process virtual
address space.  Previously for 64-bit kernels, this was not the case.
The immediate cause of pain was in
hugetlbfs/inode.c:hugetlb_get_unmapped_area() where 32-bit processes
trying to mmap a huge page would be served a page with an address
outside of the 32-bit address range.  But there are other uses of
TASK_SIZE in the kernel as well that would like an accurate value.

The new definition is nice because it now makes TASK_SIZE and
TASK_SIZE_OF() yield the same value for any given process.

For 32-bit kernels there should be no change, although I did factor
out some code in asm/processor.h that became identical for the 32-bit and
64-bit cases.

__UA_LIMIT is now set to ~((1 &lt;&lt; SEGBITS) - 1) for 64-bit kernels.
This should eliminate the possibility of getting a
AddressErrorException in the kernel for addresses that pass the
access_ok() test.

With the patch applied, I can still run o32, n32 and n64 processes,
and have an o32 shell fork/exec both n32 and n64 processes.
