After sending a RTR frame the TX mailbox becomes a RX_EMPTY mailbox. To avoid
side effects when the RX-FIFO is full, this patch puts the TX mailbox into
TX_INACTIVE mode in the transmission complete interrupt handler. This, of
course, leaves a race window between the actual completion of the transmission
and the handling of tx-complete interrupt. However this is the best we can do
without busy polling the tx complete interrupt.

This patch implements the workaround mentioned in ERR005829:
ERR005829: FlexCAN: FlexCAN does not transmit a message that is enabled to
be transmitted in a specific moment during the arbitration process.
Workaround: The workaround consists of two extra steps after setting up a
message for transmission:
Step 8: Reserve the first valid mailbox as an inactive mailbox (CODE=0b1000).
If RX FIFO is disabled, this mailbox must be message buffer 0. Otherwise, the
first valid mailbox can be found using the "RX FIFO filters" table in the
FlexCAN chapter of the chip reference manual.
Step 9: Write twice INACTIVE code (0b1000) into the first valid mailbox.

Apparently mailboxes may contain random data at startup, causing some of them
being prepared for message reception. This causes overruns being missed or even
confusing the IRQ check for trasmitted messages, increasing the transmit
counter instead of the error counter.
This patch initializes all mailboxes after the FIFO as RX_INACTIVE.

While tracking down the MAX_AH_AUTH_LEN crash in an old kernel
I thought that this limit was rather arbitrary and we should
just get rid of it.
In fact it seems that we've already done all the work needed
to remove it apart from actually removing it. This limit was
there in order to limit stack usage. Since we've already
switched over to allocating scratch space using kmalloc, there
is no longer any need to limit the authentication length.
This patch kills all references to it, including the BUG_ONs
that led me here.

Not all filesystems now provide the rename i_op - ext4 for one - but rather
provide the rename2 i_op. CacheFiles checks that the filesystem has rename
and so will reject ext4 now with EPERM:
CacheFiles: Failed to register: -1
Fix this by checking for rename2 as an alternative. The call to vfs_rename()
actually handles selection of the appropriate function, so we needn't worry
about that.
Turning on debugging shows:
[cachef] ==> cachefiles_get_directory(,,cache)

This reverts commit 4dfe694f61.
In that, we did:
Here we move the rootdelay code to be right beside the rootwait code, so
that their behaviour is consistent.
...which is fine, but in hindsight, perhaps moving the rootwait to be
beside the rootdelay would have been better. We also indicated:
It should be noted that in doing so, the actions based on the
saved_root_name[0] and initrd_load() were previously put on hold by
rootdelay=N and now currently will not be delayed. However, I think
consistent behaviour is more important than matching historical behaviour
of delaying the above two operations.
But Pavel reported an instance where an ARM target with root on MMC
was failing to mount root, and Russell diagnosed it to the fact that
the call to set ROOT_DEV within the saved_root_name[0] processing
block mentioned above was no longer being delayed.
Rather than moving both wait clauses to the original position of
rootdelay and risking unearthing other possible corner case breakage
at this point in time, we simply revert now and we can revisit
trying the alternate/earlier location in another development cycle.

The kernel code overrides the default ISA as passed by the compiler
in quite a few places. This has unfortunate side effects when smartmips
is enabled leading to hundreds of warnings during build such as:
{standard input}: Assembler messages:
{standard input}:411: Warning: the `smartmips' extension requires MIPS32
revision 1 or greater
{standard input}: Assembler messages:
{standard input}:43: Warning: the 64-bit MIPS architecture does not support the
`smartmips' extension
[...]
Until the kernel code is fixed properly (if possible), disable all the
assembler warning messages to make the build logs readable again.
This has no runtime side effects but it makes it easier to spot
more critical warnings and problems during build.

When a ranged fsync finishes if there are still extent maps in the modified
list, still set the inode's logged_trans and last_log_commit. This is important
in case an inode is fsync'ed and unlinked in the same transaction, to ensure its
inode ref gets deleted from the log and the respective dentries in its parent
are deleted too from the log (if the parent directory was fsync'ed in the same
transaction).
Instead make btrfs_inode_in_log() return false if the list of modified extent
maps isn't empty.
This is an incremental on top of the v4 version of the patch:

efx_{arch}_filter_sync_rx_mode(), which takes the addr_list_lock; but this
lock is uninitialised, because we haven't called register_netdevice() yet.
So, in efx_farch_filter_sync_rx_mode(), check efx_dev_registered() before

Commit 20cde69402 ("x86, ia64: Move EFI_FB vga_default_device()
initialization to pci_vga_fixup()") moved boot video device detection from
efifb to x86 and ia64 pci/fixup.c.
For dual-GPU Apple computers above change represents a regression as code
in efifb did forcefully override vga_default_device while the merge did not
(vgaarb happens prior to PCI fixup).
To improve on initial device selection by vgaarb (it cannot know if PCI
device not behind bridges see/decode legacy VGA I/O or not), move the
screen_info based check from pci_video_fixup() to vgaarb's init function and
use it to refine/override decision taken while adding the individual PCI
VGA devices. This way PCI fixup has no reason to adjust vga_default_device
anymore but can depend on its value for flagging shadowed VBIOS.
This has the nice benefit of removing duplicated code but does introduce a
#if defined() block in vgaarb. Not all architectures have screen_info and
would cause compile to fail without it.

We don't really need to get the platform irq again when we're
enabling or disabling the per-cpu irq. Furthermore, we don't
really need to set and clear bits in the active_irqs bitmask
because that's only used in the non-percpu irq case to figure out
when the last CPU PMU has been disabled. Just pass the irq
directly to the enable/disable functions to clean all this up.
This should be slightly more efficient and also fix the
