This patch is based on patch from Steve Magnani.

There were bug for compiled-in rootfs. We have to move
moving rootfs which is in BSS section to _ebss section
which is at the end of kernel and then clear bss section
not vice-versa.

This patch fixed parsing early parameters because
current implementation does that early parse DTS
command line and then parse CMDLINE line which is compiled-in.

For case that DTS doesn't contain command line is
copied command line from kernel with is done in prom.c
that's why I can remove it from machine_early_init.

A polarity reversal in the __KERNEL__ guard prevents the __HAVE_ARCH
flags from being defined in kernel compilation.

I noticed that there's now an option for assembly-optimized versions of
memcpy and memmove. I believe this may be buggy; when I turn it on, all
my printk output gets smashed together, as if the newlines aren't getting
copied.

This patch fix problem with bad zone initialization.
This bug wasn't perform because Microblaze doesn't
define CONFIG_ZONE_DMA and ZONE_NORMAL was 0 for this case
that's why free_area_init works with correct values.

Original message:
I believe that the switch from ZONE_DMA (== 0) to ZONE_NORMAL
broke the free area initialization.

Microblaze does not support the Linux DMA mapping API
at this point, so disable CONFIG_NO_DMA. This lets
us use the generic dma-mapping-broken.h implementation
instead of providing a different copy.

Any drivers that try to use DMA mapping now get
omitted from Kconfig or produce a link error, rather
than failing silently at run time.

This changes the function prototypes in the checksum code
to have the usual prototypes, typically by turning int
arguments into __wsum.

Also change csum_partial_copy_from_user() to operate

which is used in modular networking code.

The whole point of the __bad_xchg declaration in

The second argument of the probe method points to the amba_id

current in-tree drivers uses the pointer, so they have only been
checked for a clean compile.

Fixes a regression from commit 9d5b3ffc
('drm: fixup some of the ioctl function exit paths'): The vblank ioctl
needs to update the userspace parameters when interrupted by a signal,
which was prevented by the return code check. This could cause the X
server to hang in drmWaitVBlank().

The address range size calculation inside local_flush_tlb_kernel_range()
is being truncated by a too small size variable holder on 64-bit systems.
The truncated size can result in an erroneous tlbsize check that means we
sit spinning inside a loop trying to flush a hige number of TLB entries.
This is for all intents and purposes a system hang. Fix by using an
appropriately sized valiable to hold the size.

[Ralf: Greg's original patch submission identified the issue and fixed one
instance in tlb-r4k.c but there there were several more.  For consistency
I also modified tlb-r3k.c even though that file is only used on 32-bit.]

  futex: setup writeable mapping for futex ops which modify user space data

Currently, userspace can fail to obtain the SAREA mapping (among other
reasons) if it passes SAREA_MAX to drmAddMap without aligning it to the
page size. This breaks for example on PowerPC with 64K pages and radeon
despite the kernel radeon actually doing the right rouding in the first
place.

The way SAREA_MAX is defined with a bunch of ifdef's and duplicated
between libdrm and the X server is gross, ultimately it should be
retrieved by userspace from the kernel, but in the meantime, we have
plenty of existing userspace built with bad values that need to work.

This patch works around broken userspace by rounding the requested size
in drm_addmap_core() of any SHM map to the page size. Since the backing
memory for SHM maps is also allocated within addmap_core, there is no
danger of adjacent memory being exposed due to the increased map size.
The only side effect is that drivers that previously tried to create or
access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL),
will now succeed at the cost of a little bit more memory used if that
happens to be when the map is created.
