Revision 06d1d8c85700884940346f20d10b3a22c331b5e9 authored by Arnd Bergmann on 02 April 2013, 14:08:43 UTC, committed by Arnd Bergmann on 02 April 2013, 14:09:45 UTC 
Merge tag 'v3.9-rc1_cns3xxx_fixes' of git://git.infradead.org/users/cbou/linux-cns3xxx into fixes
 
From Anton Vorontsov <anton@enomsg.org>:

This tag includes Mac Lin's work to revive CNS3xxx booting:

 "Since commit 0536bdf33faf (ARM: move iotable mappings within the vmalloc
 region), [...] the pre-defined iotable mappings is not in the vmalloc
 region. [...] move the iotable mappings into the vmalloc region, and
 merge the MPCore private memory region (containing the SCU, the GIC and
 the TWD) as a single region."

Plus there is a small cosmetic fix, also from Mac Lin.

* tag 'v3.9-rc1_cns3xxx_fixes' of git://git.infradead.org/users/cbou/linux-cns3xxx:
  ARM: cns3xxx: fix mapping of private memory region

[arnd: dropped the cosmetic fix from the merge as it is not needed for 3.9]
