The range_cyclic writeback mode uses the address_space writeback_index
as the start index for writeback. With delayed allocation we were
updating writeback_index wrongly resulting in highly fragmented file.
This patch reduces the number of extents reduced from 4000 to 27 for a

If no_nrwrite_index_update is set we don't update nr_to_write and
address space writeback_index in write_cache_pages. This change
enables a file system to skip these updates in write_cache_pages and do
them in the writepages() callback. This patch will be followed by an
ext4 patch that make use of these new flags.

Impact: crash on module insertion with CONFIG_DEBUG_VIRTUAL
We would incorrectly BUG due to:
VIRTUAL_BUG_ON(!is_vmalloc_addr(vmalloc_addr) &&
!is_module_address(addr));
... because, at least on x86-64, is_module_address() doesn't do what
it should. This patch introduces is_vmalloc_or_module_addr(), which
is what we really want anyway, and uses it instead.

On the GM45, the amount of stolen memory mapped to the GTT was underestimated,
even though we had 508KB more available since the GTT doesn't take from
stolen memory. On the non-GM45 G4X, we overestimated how much stolen was
mapped to the GTT by 4KB, resulting in GPU page faults when that page was
accessed.

correctly.

Problem observed:
In IPv6, in the presence of multiple routers candidates to
default gateway in one segment, each sending a different
value of preference, the Linux hosts connected to the
segment weren't selecting the right one in all the
combinations possible of LOW/MEDIUM/HIGH preference.
This patch changes two files:
include/linux/icmpv6.h
Get the "router_pref" bitfield in the right place
(as RFC4191 says), named the bit left with this fix as
"home_agent" (RFC3775 say that's his function)
net/ipv6/ndisc.c
Corrects the binary logic behind the updating of the
router preference in the flags of the routing table
Result:
With this two fixes applied, the default route used by
the system was to consistent with the rules mentioned
in RFC4191 in case of changes in the value of preference
in router advertisements

queuecommand() looked at the remote and local node IDs before it read
the bus generation. The corresponding race with sbp2_reconnect updating
these data was probably impossible to happen though because the current
code blocks the SCSI layer during reconnection. However, better safe
than sorry, especially if someone later improves the code to not block
the SCSI layer.

1. We don't need to round the SBP-2 segment size limit down to a
multiple of 4 kB (0xffff -> 0xf000). It is only necessary to
ensure quadlet alignment (0xffff -> 0xfffc).
2. Use dma_set_max_seg_size() to tell the DMA mapping infrastructure
and the block IO layer about the restriction. This way we can
remove the size checks and segment splitting in the queuecommand
path.
This assumes that no other code in the firewire stack uses
dma_map_sg() with conflicting requirements. It furthermore assumes
that the controller device's platform actually allows us to set the
segment size to our liking. Assert the latter with a BUG_ON().
3. Also use blk_queue_max_segment_size() to tell the block IO layer
about it. It cannot know it because our scsi_add_host() does not
point to the FireWire controller's device.
