The driver needs to inform the hardware about the first invalid (not yet
filled) rx slot, by writing its DMA descriptor pointer offset to the
BGMAC_DMA_RX_INDEX register.
This register was set to a value exceeding the rx ring size, effectively
allowing the hardware constant access to the full ring, regardless of
which slots are initialized.
To fix this issue, always mark the last filled rx slot as invalid.

of the TRACE_DEFINE_ENUM() macro that can be used by tracepoints.
Tracepoints have helper functions for the TP_printk() called
__print_symbolic() and __print_flags() that lets a numeric number be
displayed as a a human comprehensible text. What is placed in the
TP_printk() is also shown in the tracepoint format file such that
user space tools like perf and trace-cmd can parse the binary data
and express the values too. Unfortunately, the way the TRACE_EVENT()
macro works, anything placed in the TP_printk() will be shown pretty
much exactly as is. The problem arises when enums are used. That's
because unlike macros, enums will not be changed into their values
by the C pre-processor. Thus, the enum string is exported to the
format file, and this makes it useless for user space tools.
The TRACE_DEFINE_ENUM() solves this by converting the enum strings
in the TP_printk() format into their number, and that is what is
shown to user space. For example, the tracepoint tlb_flush currently
has this in its format file:
__print_symbolic(REC->reason,
{ TLB_FLUSH_ON_TASK_SWITCH, "flush on task switch" },
{ TLB_REMOTE_SHOOTDOWN, "remote shootdown" },
{ TLB_LOCAL_SHOOTDOWN, "local shootdown" },
{ TLB_LOCAL_MM_SHOOTDOWN, "local mm shootdown" })

TRACE_DEFINE_ENUM(TLB_REMOTE_SHOOTDOWN);
TRACE_DEFINE_ENUM(TLB_LOCAL_SHOOTDOWN);
TRACE_DEFINE_ENUM(TLB_LOCAL_MM_SHOOTDOWN);
Its format file will contain this:
__print_symbolic(REC->reason,
{ 0, "flush on task switch" },
{ 1, "remote shootdown" },
{ 2, "local shootdown" },
{ 3, "local mm shootdown" })

more than one release, as I had it ready for the 4.0 merge window, but
a last minute thing that needed to go into Linux first had to be done.
That was that perf hard coded the file system number when reading
/sys/kernel/debugfs/tracing directory making sure that the path had
the debugfs mount # before it would parse the tracing file. This broke
other use cases of perf, and the check is removed.
Now when mounting /sys/kernel/debug, tracefs is automatically mounted
in /sys/kernel/debug/tracing such that old tools will still see that
path as expected. But now system admins can mount tracefs directly
and not need to mount debugfs, which can expose security issues.
A new directory is created when tracefs is configured such that
system admins can now mount it separately (/sys/kernel/tracing).
This branch is based off of Al Viro's vfs debugfs_automount branch
at commit 163f9eb95a
debugfs: Provide a file creation function that also takes an initial size
to get the debugfs_create_automount() operation.
I just noticed that Al rebased the pull to add his Signed-off-by to

====================
netdev-related stuff in vfs.git
There are several commits sitting in vfs.git that probably ought to go in
via net-next.git. First of all, there's merge with vfs.git#iocb - that's
Christoph's aio rework, which has triggered conflicts with the ->sendmsg()
and ->recvmsg() patches a while ago. It's not so much Christoph's stuff
that ought to be in net-next, as (pretty simple) conflict resolution on merge.
The next chunk is switch to {compat_,}import_iovec/import_single_range - new
safer primitives for initializing iov_iter. The primitives themselves come
from vfs/git#iov_iter (and they are used quite a lot in vfs part of queue),
conversion of net/socket.c syscalls belongs in net-next, IMO. Next there's
afs and rxrpc stuff from dhowells. And then there's sanitizing kernel_sendmsg
et.al. + missing inlined helper for "how much data is left in msg->msg_iter" -
this stuff is used in e.g. cifs stuff, but it belongs in net-next.
That pile is pullable from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-davem
I'll post the individual patches in there in followups; could you take a look
and tell if everything in there is OK with you?

Another release, another set of regulator updates. Not much of it is
showing up in the code yet but there's been a lot of discussion going on
about how to enhance the regulator API to work better with modern SoCs
which have a microcontroller sitting between Linux and the hardware.
I'm hopeful that'll start to come through into mainline for v4.2 but
it's not quite there for v4.1 - what we do have (along with the usual
small updates is) is:
- Work from Bjorn Andersson on refactoring the configuration of
regulator loading interfaces to be useful for use with
microcontrollers, the existing interfaces were never actually useful
for anything as-is since nobody was willing to put enough data into
public code.
- A summary tree display in debugfs from Heiko Stübner.
- Support for act6000 regulators.

all driver updates:
- Make the spidev driver complain loudly if registered as spidev with
DT rather than with a compatible string, hopefully helping people
avoid making that mistake.
- Error handling and robustness fixes for the Designware and Intel MID
drivers from Andy Shevchenko.
- Substantial performance improvements for the Raspberry Pi driver from
Martin Sperl.
