Commit d50240a5f6 ("arm64: mm: permit use of tagged pointers at EL0")
added support for tagged pointers in userspace, but the corresponding
update to Documentation/ contained some imprecise statements.
This patch fixes up some minor ambiguities in the text, hopefully making
it more clear about exactly what the kernel expects from user virtual

A set of fixes for ARM platforms for 3.12. Among them:
- A fix for build breakage in the MTD subsystem for some PXA devices.
David Woodhouse has this patch in his for-next branch but has not been
responding to our requests to send it up so here it is.
I should have amended the commit message to describe the build failure for
CONFIG_OF=n setups, but forgot and now it's down in the stack of commits.
- Added device-tree for the BeagleBone Black. Turns out people have been
using the older "regualar" bone DT for the newer boards, and there's
risk of damaging hardware that way.
- Misc DT and regular fixes for OMAP.
- Fix to make the ST-Ericsson "snowball" boards boot with
multi_v7_defconfig, and enable one of the ST-E reference boards on the
same config.
- Kconfig cleanup for u300 to hide submenus when the platform isn't
enabled.
- Enable ARM_ATAG_DTB_COMPAT to let firmware override command
line when booting with an appended devicetree on non-DT-enabled
firmware (needed to boot snowball).

This bug was introduced by commit
7a163bfb7c ("netconsole: avoid a crash with
multiple sysfs writers"). In store_enabled() we have the following
sequence: acquire nt->mutex then rtnl, but in the netconsole netdev
notifier we have rtnl then nt->mutex effectively leading to a deadlock.
The NULL pointer dereference that the above commit tries to fix is
actually due to another bug in netpoll_cleanup(). This is fixed by dropping
the mutex from the netdev notifier as it's already protected by rtnl.

I've been hitting a NULL ptr deref while using netconsole because the
np->dev check and the pointer manipulation in netpoll_cleanup are done
without rtnl and the following sequence happens when having a netconsole
over a vlan and we remove the vlan while disabling the netconsole:
CPU 1 CPU2
removes vlan and calls the notifier
enters store_enabled(), calls
netdev_cleanup which checks np->dev
and then waits for rtnl
executes the netconsole netdev
release notifier making np->dev
== NULL and releases rtnl
continues to dereference a member of
np->dev which at this point is == NULL

The patch 136d8f377e broke the skge driver.
Note this part of the patch:
+ if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) {
+ dev_kfree_skb(nskb);
+ goto resubmit;
+ }
+
pci_unmap_single(skge->hw->pdev,
dma_unmap_addr(e, mapaddr),
dma_unmap_len(e, maplen),
PCI_DMA_FROMDEVICE);
skb = e->skb;
prefetch(skb->data);
- skge_rx_setup(skge, e, nskb, skge->rx_buf_size);
The function skge_rx_setup modifies e->skb to point to the new skb. Thus,
after this change, the new buffer, not the old, is returned to the
networking stack.
This bug is present in kernels 3.11, 3.11.1 and 3.12-rc1. The patch should
be queued for 3.11-stable.

If local fragmentation is allowed, then ip_select_ident() and
ip_select_ident_more() need to generate unique IDs to ensure
correct defragmentation on the peer.
For example, if IPsec (tunnel mode) has to encrypt large skbs
that have local_df bit set, then all IP fragments that belonged
to different ESP datagrams would have used the same identificator.
If one of these IP fragments would get lost or reordered, then
peer could possibly stitch together wrong IP fragments that did
not belong to the same datagram. This would lead to a packet loss
or data corruption.

Without this patch, if a frontend cycles through states Closing
and Closed (which Windows frontends need to do) then the netdev
will be destroyed and requires re-invocation of hotplug scripts
to restore state before the frontend can move to Connected. Thus
when udev is not in use the backend gets stuck in InitWait.
With this patch, the netdev is left alone whilst the backend is
still online and is only de-registered and freed just prior to
destroying the vif (which is also nicely symmetrical with the
netdev allocation and registration being done during probe) so
no re-invocation of hotplug scripts is required.

Otherwise the system will burn even brighter and worse, leave the user

Since we already have a panic handler which will (try) to restore the
entire fbdev console mode, we can just bail out. Inspired by a patch from
Konstantin Khlebnikov. The callchain leading to this, cut&pasted from
Konstantin's original patch:
callstack:
panic()
bust_spinlocks(1)
unblank_screen()
vc->vc_sw->con_blank()
fbcon_blank()
fb_blank()
info->fbops->fb_blank()
drm_fb_helper_blank()
drm_fb_helper_dpms()
drm_modeset_lock_all()
mutex_lock(&dev->mode_config.mutex)
Note that the entire locking in the fb helper around panic/sysrq and kdbg
is ... non-existant. So we have a decent change of blowing up
everything. But since reworking this ties in with funny concepts like the
fbdev notifier chain or the impressive things which happen around
console_lock while oopsing, I'll leave that as an exercise for braver
souls than me.

After a vmalloc failure in ttm_dma_tt_alloc_page_directory(),
ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up
inside the driver's unpopulate() hook when populate() has never yet
been called.
On nouveau, the first issue to be hit because of this is that
dma_address[] may be a NULL pointer. After working around this,
ttm_pool_unpopulate() may potentially hit the same issue with
the pages[] array.
It seems to make more sense to avoid calling unpopulate on already
unpopulated TTMs than to add checks to all the implementations.

Looks like we still have the legacy clock alias name for
omap4 GPMC (General Purpose Memory Controller), so let's
fix it for the device tree naming. There's no need to keep
the legacy naming as omap4 is DT only nowadays.
Without this fix we get the following error while booting:
[ 0.440399] omap-gpmc 50000000.gpmc: error: clk_get

1) Better adjustment of size of compression buffer (was too big
for EFIVARS backend resulting in compression failure
2) Use zlib_inflateInit2 instead of zlib_inflateInit
3) Don't print messages about compression failure. They will
waste space that may better be used to log console output
leading to the crash.

We need to let the setup stage complete cleanly even when the HCI device
is rfkilled. Otherwise the HCI device will stay in an undefined state
and never get notified to user space through mgmt (even when it gets
unblocked through rfkill).
This patch makes sure that hci_dev_open() can be called in the HCI_SETUP
stage, that blocking the device doesn't abort the setup stage, and that
the device gets proper powered down as soon as the setup stage completes
in case it was blocked meanwhile.
The bug that this patch fixed can be very easily reproduced using e.g.
the rfkill command line too. By running "rfkill block all" before
inserting a Bluetooth dongle the resulting HCI device goes into a state
where it is never announced over mgmt, not even when "rfkill unblock all"
is run.

This makes it more convenient to check for rfkill (no need to check for
dev->rfkill before calling rfkill_blocked()) and also avoids potential
races if the RFKILL state needs to be checked from within the rfkill
callback.

commit 104a43edb2
cnic: Use CHIP_NUM macros from bnx2x.h
changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE
is supported or not. There is another place in cnic that is still using
the old method to determine if FCoE is supported or not. The 2 methods
may not yield the same result after the network interface is brought down
and up. This will cause the crash as cnic_bnx2x_service_kcq() will access
the uninitialized cp->kcq2.
The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which
uses the bnx2x NO_FCOE() macro. As a follow-up, we can clean up the code
to remove the old method as it is no longer needed.

changed the configuration of the doorbell HW and it broke iSCSI and FCoE.
We fix this by making compatible changes to the doorbell address in bnx2i

so that the existing userspace driver will calculate the correct doorbell
address and continue to work.
