[PATCH v6 0/8] linux-user: brk fixes

[Helge Deller <deller@gmx.de>]

This patch series is a fix-up for some current problems
regarding heap memory / brk handling in qemu which happens
on some 32-bit platforms, e.g. problems loading static
binaries.

This series includes the 5 patches from Akihiko Odaki
with some additional fixes and cleanups by me.

Akihiko Odaki (5):
  linux-user: Unset MAP_FIXED_NOREPLACE for host
  linux-user: Do not call get_errno() in do_brk()
  linux-user: Use MAP_FIXED_NOREPLACE for do_brk()
  linux-user: Do nothing if too small brk is specified
  linux-user: Do not align brk with host page size

Helge Deller (3):
  linux-user: Show heap address in /proc/pid/maps
  linux-user: Optimize memory layout for static and dynamic executables
  linux-user: Load pie executables at upper memory
