A recent patch fixed a problem which would occur when the refcount on an
auth_domain reached zero. This problem has not been reported in practice
despite existing in two major kernel releases because the refcount can
never reach zero.
This patch fixes the problems that stop the refcount reaching zero.
1/ We were adding to the refcount when inserting in the hash table,
but only removing from the hashtable when the refcount reached zero.
Obviously it never would. So don't count the implied reference of
being in the hash table.
2/ There are two paths on which a socket can be destroyed. One called
svcauth_unix_info_release(). The other didn't. So when the other was
taken, we can lose a reference to an ip_map which in-turn holds a
reference to an auth_domain
So unify the exit paths into svc_sock_put. This highlights the fact
that svc_delete_socket has slightly odd semantics - it does not drop
a reference but probably should. Fixing this need a bit more
thought and testing.

From: Jeff Dike <jdike@addtoit.com>, Paolo Giarrusso <blaisorblade@yahoo.it>
Make sure that when compiling USER_OBJS the correct compilation options are
passed; since they are compiled with USER_CFLAGS which is derived from
CFLAGS, make sure it is a recursively evaluated variable, so that changes
to CFLAGS done afterwards the inclusion of arch/$(ARCH)/Makefile are
reflected in USER_CFLAGS.
For instance, without this patch userspace objects are never compiled with
debug info active.

Fix commit 5f4c6bc1f369f20807a8e753c2308d1629478c61: it spits out warnings
about missing syscall prototype (it is in <unistd.h>) and it does not
recognize that two uses of _syscallX are to be resolved against kernel
headers in the source tree, not against _syscallX; they in fact do not
compile and would not work anyway.
If _syscallX macros will be removed from the kernel tree altogether, the
only reasonable solution for that piece of code is switching to open-coded
inline assembly (it's remapping the whole executable from memory, except
the page containing this code).

This reverts commit a2b98a697fa4e7564f78905b83db122824916cf9.
As per Guennadi Liakhovetski, the mac address change support code breaks
some normal uses (_without_ any address changes), and until it's all
sorted out, we're better off without it.
Says Francois:
"Go revert it.
Despite what I claimed, I can not find a third-party confirmation by
email that it works elsewhere.
It would probably be enough to remove the call to
__rtl8169_set_mac_addr() in rtl8169_hw_start() though."

As reported by Martin J. Bligh <mbligh@google.com>, we let through some
non-slab bits to slab allocation through __get_vm_area_node when doing a
vmalloc.
I haven't been able to reproduce this, although I understand why it
happens: vmalloc allocates memory with
GFP_KERNEL | __GFP_HIGHMEM
and commit 52fd24ca1db3a741f144bbc229beefe044202cac resulted in the same
flags are passed down to cache_alloc_refill, causing the BUG. The
following patch fixes it.
Note that when calling kmalloc_node, I am masking off __GFP_HIGHMEM with
GFP_LEVEL_MASK, whereas __vmalloc_area_node does the same with
~(__GFP_HIGHMEM | __GFP_ZERO).
IMHO, using GFP_LEVEL_MASK is preferable, but either should fix this
problem.

absent_pages_in_range() made the assumption that users of the
arch-independent zone-sizing API would not care about holes beyound the end
of physical memory. This was not the case and was "fixed" in a patch
called "Account for holes that are outside the range of physical memory".
However, when given a range that started before a hole in "real" memory and
ended beyond the end of memory, it would get the result wrong. The bug is
in mainline but a patch is below.
It has been tested successfully on a number of machines and architectures.
