Unlike normal kfree() it is never right to call sock_kfree_s() with
a NULL pointer, because sock_kfree_s() also has the side effect of
discharging the memory from the sockets quota.

It is okay to free a NULL pointer but not okay to mischarge the socket optmem
accounting. Compile test only.

To follow vm_area_struct->vm_end convention.
By adhering to the convention that ->end is the first address outside
the symbol's range we can do things like:
sym->end = start + len;
len = sym->end - sym->start;
This is also now the convention used for struct map->end, fixing some
off-by-one bugs.

This patch fixes off-by-one errors in the management of maps.
A map is defined by start address and length as implemented by
map__new():
map__init(map, type, start, start + len, pgoff, dso);
map->start = addr;
map->end = end;
Consequently, the actual address range is [start; end[ map->end is the
first byte outside the range.
This patch fixes two bugs where upper bound checking was off-by-one.
In V2, we fix map_groups__fixup_overlappings() some more where
map->start was off-by-one as reported by Jiri.

A segfault happens on 'perf test hists_link' because we end up using a
struct machines on the stack, and then machines__init() was not
initializing the newly introduced rb_root, just the existing list_head.
When we introduced struct dsos, to group the two ways to store dsos,
i.e. the linked list and the rbtree, we didn't turned the initialization
done in:
machines__init(machines->host) ->
machine__init() ->
INIT_LIST_HEAD
into a dsos__init() to keep on initializing the list_head but _as well_
initializing the rb_root, oops.
All worked because outside perf-test we probably zalloc the whole thing
which ends up initializing it in to NULL.
So the problem looks contained to 'perf test' that uses it on stack,
etc.

stmmac: review and fix the dwmac-sti glue-logic
This patch is to review the whole glue logic adopted on STi SoCs that
was bugged.
In the old glue-logic there was a lot of confusion when setup the
retiming especially for STiD127 where, for example, the bits 6 and 7
(in the GMAC control register) have a different meaning of what is
used for STiH4xx SoCs. So we cannot adopt the same glue for all these
SoCs.
Moreover, GiGa on STiD127 didn't work and, for all the SoCs, the RGMII
couldn't run when the speed was 10Mbps (because the clock was not properly
managed).
Note that the phy clock needs to be provided by the platform as well as
documented in the related binding file (updated as consequence).
The old code supported too many configurations never adopted and validated.
This made the code very complex to maintain and debug in case of issues.
The patch simplifies all the configurations as commented in the tables
inside the file and obviously it has been tested on all the boards
based on the SoCs mentioned.
With this patch, the dwmac-sti is also ready to support new configurations that
will be available on next SoC generations.

We still have one spurious access because of ACK timestamping,
added in commit e1c8a607b2 ("net-timestamp: ACK timestamp for

By checking if sk_tsflags has SOF_TIMESTAMPING_TX_ACK set,
we can avoid two cache line misses for the common case.
While we are at it, add two prefetchw() :
One in tcp_ack() to bring skb at the head of write queue.
One in tcp_clean_rtx_queue() loop to bring following skb,
as we will delete skb from the write queue and dirty skb->next->prev.

Current code uses page array to present MDS request data. Pages in the
array are allocated/freed by caller of ceph_mdsc_do_request(). If request
is interrupted, the pages can be freed while they are still being used by
the request message.
The fix is use pagelist to present MDS request data. Pagelist is
reference counted.
