The b44 build uses these, caught by allmodconfig:
drivers/net/b44.c: In function `b44_sync_dma_desc_for_cpu':
drivers/net/b44.c:159: error: implicit declaration of function `dma_sync_single_range_for_cpu'
Follow the sparc64 change and stub them in.

Now that __initmv references the machvec section unconditionally
there have been cases where folks have been mistakenly flagging
non-machvec structures with the machvec section attribute (presumably
to shut up modpost). This leads to obscure breakage in earlyprintk
amongst other places and is rather non-obvious.
Add a simple sanity check to try and catch __initmv misuse and
panic early.

When generic_ptrace_peekdata() was merged, the break for these cases
ended up getting dropped, which lead to each PEEKTEXT/PEEKDATA op leaking
in to PEEKUSR and get_user_pages() always -EFAULTing. Add the break back
in.

There is a couple of subtle checks which were needed to handle ptracing from
the same thread group. This was deprecated a long ago, imho this code just
complicates the understanding.
And, the "->parent->signal->flags & SIGNAL_GROUP_EXIT" check in exit_notify()
is not right. SIGNAL_GROUP_EXIT can mean exec(), not exit_group(). This means
ptracer can lose a ptraced zombie on exec(). Minor problem, but still the bug.

On a machine with hardware 64kB pages and a kernel configured for a
64kB base page size, we need to change the vmalloc segment from 64kB
pages to 4kB pages if some driver creates a non-cacheable mapping in
the vmalloc area. However, we never updated with SLB shadow buffer.
This fixes it. Thanks to paulus for finding this.
Also added some write barriers to ensure the shadow buffer contents
are always consistent.

Some new machines use the "ibm,dynamic-reconfiguration-memory" property
to provide memory layout information, rather than via memory nodes.
There is a bug in the code to parse this property for start addresses
over 4GB; we store the start address in an unsigned int, which means
we throw away the high bits and add apparently duplicate regions.
This results in a BUG() in free_bootmem_core(). This fixes it by
using an unsigned long instead.

In smp_call_function_map(), num_cpus is set to the number of online
CPUs minus one. However, if the CPU mask does not include all CPUs
(except the one we're running on), the routine will hang in the first
while() loop until the 8 second timeout occurs.
The num_cpus should be set to the number of CPUs specified in the mask
passed into the routine, after we've made any modifications to the
mask. With this change, we can also get rid of the call to
cpus_empty() and avoid adding another pass through the bitmask.

This patch fixes affinity reference point placement, which was not being
done in some situations, after the introduction of node_allowed() calls.
The previously used parameter, 'ctx', is just the iterator of the
previous list_for_each_entry_reverse loop, and its value might be
invalid at the end of the loop. Also, the right context to seek
for information when defining the reference ctx location
_is_ the reference ctx.

The code for mapping special 4k pages on kernels using a 64kB base
page size was missing the code for doing the RPN (real page number)
manipulation when inserting the hardware PTE in the secondary hash
bucket. It needs the same code as has already been added to the
code that inserts the HPTE in the primary hash bucket. This adds it.
Spotted by Ben Herrenschmidt.

The real page number field in our PTEs when configured for 64kB pages
is currently 32 bits, which turns out to be not quite enough for the
resources that the eHCA driver wants to map. This expands the RPN
field to include 2 adjacent, previously-unused bits.

tcp_cwnd_down must check for it too as it should be conservative
in case of collapse stuff and also when receiver is trying to
lie (though that wouldn't be very successful/useful anyway).
Note:
- Separated also is_dupack and do_lost in fast_retransalert
* Much cleaner look-and-feel now
* This time it really fixes cumulative ACK with many new
SACK blocks recovery entry (I claimed this fixes with
last patch but it wasn't). TCP will now call
tcp_update_scoreboard regardless of is_dupack when
in recovery as long as there is enough fackets_out.
- Introduce FLAG_SND_UNA_ADVANCED
* Some prior_snd_una arguments are unnecessary after it
- Added helper FLAG_ANY_PROGRESS to avoid long FLAG...|FLAG...

Although an ipsec SA was established, kernel couldn't seem to find it.
I think since we are now using "x->sel.family" instead of "family" in
the xfrm_selector_match() called in xfrm_state_find(), af_key needs to
set this field too, just as xfrm_user.
In af_key.c, x->sel.family only gets set when there's an
ext_hdrs[SADB_EXT_ADDRESS_PROXY-1] which I think is for tunnel.
I think pfkey needs to also set the x->sel.family field when it is 0.
Tested with below patch, and ipsec worked when using pfkey.

As discovered by Evegniy Polyakov, if we try to sendmsg after
a connection reset, we can do incredibly stupid things.
The core issue is that inet_sendmsg() tries to autobind the
socket, but we should never do that for TCP. Instead we should
just go straight into TCP's sendmsg() code which will do all
of the necessary state and pending socket error checks.
TCP's sendpage already directly vectors to tcp_sendpage(), so this
merely brings sendmsg() in line with that.

This patch fixes up the defconfig for various sh7751r based boards
by updating them to the single cpu subtype CONFIG_CPU_SUBTYPE_SH7751R.
The following sh4 boards are updated: hs7751rvoip, landisk, lboxre2,
systemh, titan.
The current defconfigs with two subtypes defined trigger a configuration
bug which result in kernel configurations with missing board support
code. We end up with kernels without board code and with generic machvec
only.
So we need this patch to make sure the board code gets compiled in.
