rtc: fix build warnings in defconfigs

2011-06-16T03:04:02+00:00

RTC_CLASS is changed to bool, so 'm' is invalid.

powerpc: Force page alignment for initrd reserved memory

2011-06-09T06:52:38+00:00

When using 64K pages with a separate cpio rootfs, U-Boot will align
the rootfs on a 4K page boundary. When the memory is reserved, and
subsequent early memblock_alloc is called, it will allocate memory
between the 64K page alignment and reserved memory. When the reserved
memory is subsequently freed, it is done so by pages, causing the
early memblock_alloc requests to be re-used, which in my case, caused
the device-tree to be clobbered.

This patch forces the reserved memory for initrd to be kernel page
aligned, and will move the device tree if it overlaps with the range
extension of initrd. This patch will also consolidate the identical
function free_initrd_mem() from mm/init_32.c, init_64.c to mm/mem.c,
and adds the same range extension when freeing initrd. free_initrd_mem()
is also moved to the __init section.

Many thanks to Milton Miller for his input on this patch.

dtc/powerpc: remove obsolete .gitignore entries

2011-06-09T00:51:18+00:00

dtc was moved and .gitignores have been added to the new location. So, we can
delete the old, forgotten ones.

powerpc/book3e: Fix CPU feature handling on e5500 in 32-bit mode

2011-06-02T20:29:09+00:00

We are missing FPU feature bit that user space may require.  In the
64-bit mode this gets set since we pull it in via COMMON_USER_PPC64.  We
just explicitly set it so user space will be happy again.

powerpc/pmac: Don't register pmac PIC syscore ops when HW not present

2011-05-31T11:30:20+00:00

The Apple custom PIC only exist in some earlier machine models,
anything with an MPIC will crash on suspend if we register those
syscore ops unconditionally.

This is a regression caused by commit f5a592f7d74e ("PM / PowerPC: Use
struct syscore_ops instead of sysdevs for PM")

Merge branch 'setns'

2011-05-28T17:51:01+00:00

* setns:
  ns: Wire up the setns system call

Done as a merge to make it easier to fix up conflicts in arm due to
addition of sendmmsg system call

ns: Wire up the setns system call

2011-05-28T17:48:39+00:00

32bit and 64bit on x86 are tested and working.  The rest I have looked
at closely and I can't find any problems.

setns is an easy system call to wire up.  It just takes two ints so I
don't expect any weird architecture porting problems.

While doing this I have noticed that we have some architectures that are
very slow to get new system calls.  cris seems to be the slowest where
the last system calls wired up were preadv and pwritev.  avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h.  frv is
behind with perf_event_open being the last syscall wired up.  On h8300
the last system call wired up was epoll_wait.  On m32r the last system
call wired up was fallocate.  mn10300 has recvmmsg as the last system
call wired up.  The rest seem to at least have syncfs wired up which was
new in the 2.6.39.

v2: Most of the architecture support added by Daniel Lezcano 
v3: ported to v2.6.36-rc4 by: Eric W. Biederman 
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
v7: ported to Linus's latest post 2.6.39 tree.
