If we write to a known-bad-block it will be flags as having
a ReadError by analyse_stripe, but the write will proceed anyway
(as it should). Then the read-error handling will kick in an
write again, then re-read.
We don't need that 'write-again', so set R5_ReWrite so it looks like
it has already been done. Then we will just get the re-read, which we
want.

As the function call is the most expensive of these tests it should be
done later in the chain so that it can be avoided in some cases.

The value returned by test_and_set_bit_le() drivers/md/bitmap.c is not used.
So just use set_bit_le(). The same goes for test_and_clear_bit_le().

If a fail device or a spare is removed from an array, there is
not need to make the array 'active'. If/when the array does become
active for some other reason the metadata will be update to reflect
the removal.
If that never happens and the array is stopped while still read-auto,
then there is no loss in forgetting the that the device had 'failed'.
A read-only array will leave failed devices attached to
the array personality, so we need to explicitly call
remove_and_add_spares() to free it (clearing Blocked just
like we do in store_slot()).

slot_store and remove_and_add_spares both call ->hot_remove_disk(),
but with slightly different tests and consequences, which is
at least untidy and might be buggy.
So modify remove_and_add_spaces() so that it can be asked
to remove a specific device, and call it from slot_store().
We also clear the Blocked flag to ensure that doesn't prevent
removal. The purpose of Blocked is to prevent automatic removal
by the kernel before an error is acknowledged.
If the array is read/write then user-space would have not reason
to remove a device unless it was known to be 'spare' or 'faulty' in
which it would have already cleared the Blocked flag.
If the array is read-only, the flag might still be blocked, but
there is no harm in clearing the flag for read-only arrays.

Normally we don't even try to update the metadata if
the array is read-only. However future patches
will increase the number of things that can happen on a read-only
array, so it is safest to explicitly disable this.
Every time that mddev->ro is set to 0, either
- md_update_sb will be called again (at least if MD_CHANGE_DEVS
is set) or
- the mddev->thread is scheduled, which will also run
md_update_sb if needed.
So this is safe: if the array ever become read-write the
metadata will be updated.

fbcon: don't lose the console font across generic->chip driver switch
uses a pointer in vc->vc_font.data to load font into the new driver.
However if the font is actually freed, we need to clear the data
so that we don't reload font from dangling pointer.

FW does the synchronization of the different modules during init.
It will report different modules, that it is ready at different times.
The fw download 'winner' will be reported fw ready first. Without this
patch, btmrvl was already continuing before the FW told it too. Probably
on behalf of the 'winner' which then never sees FW ready and times out.

The Bluetooth Core Specification (4.0) defines the Write LE Host
Supported HCI command as only available for controllers supporting
BR/EDR. This is further reflected in the Read Local Extended Features
HCI command also not being available for LE-only controllers. In other
words, host-side LE support is implicit for single-mode LE controllers
and doesn't have explicit HCI-level enablement.
This patch ensures that the LE setting is always exposed as enabled
through mgmt and returns a "rejected" response if user space tries to
toggle the setting. The patch also ensures that Write LE Host Supported
is never sent for LE-only controllers.

send_packet() is used during initialization, before send_packet_delay
is set. So, move ictx->send_packet_delay to happen earlier.

CONFIG_COMEDI_NI_LABPC_ISA is a tristate option. #if IS_ENABLED()
needs to be used instead of #ifdef in order to build the legacy
specific code in this driver.
The local variable 'board' is not used in labpc_attach(). Remove it.
The labpc_detach() function is only referenced in this file. Make
it static.

Both phy-tegra-usb.c and ehci-tegra.c export symbols used by the other one,
which does not work if one of them or both are loadable modules, resulting
in an error like:
drivers/built-in.o: In function `utmi_phy_clk_disable':
drivers/usb/phy/phy-tegra-usb.c:302: undefined reference to `tegra_ehci_set_phcd'
drivers/built-in.o: In function `utmi_phy_clk_enable':

drivers/built-in.o: In function `utmi_phy_power_on':
drivers/usb/phy/phy-tegra-usb.c:447: undefined reference to `tegra_ehci_set_pts'
This turns the interface into a one-way dependency by letting the tegra ehci
driver pass two function pointers for callbacks that need to be called by
the phy driver.

Rotate bss prio list, so the bss next to the one served, will come first
in the list of bss' with equal priority. This way we pick bss nodes in a
round robin fashion. Using list rotation instead of a cur ptr simplifies
iteration to calling list_for_each_entry. List rotation is done via
list_move, where the head itself is temporarily removed and then
re-inserted after the bss just served.

After a packet is successfully transmitted, ra list is rotated, so the ra
next to the one transmitted, will be the first in the list. This way we
pick the ra' in a round robin fashion. This significantly simplifies
iteration in mwifiex_wmm_get_highest_priolist_ptr to a call to
list_for_each_entry.
List rotation is done via list_move, where the head itself is temporarily
removed and then re-inserted after the item just transferred.

CONFIG_ARCH_OMAP2PLUS depends on (ARCH_MULTI_V6 || ARCH_MULTI_V7) as of
a0694861 "ARM: OMAP2+: Enable ARCH_MULTIPLATFORM support", but the
individual OMAP2/3/4/5 and AM33XX platforms can all be selected independent
of what we are building for, which is a bug and prevents us from easily
building e.g. an ARMv7-only defconfig.
This makes ARCH_OMAP2 depend on ARCH_MULTI_V6 and the others depend on
ARCH_MULTI_V7, to ensure we really only build the platforms for the
CPUs we have enabled in the global multiplatform configuration step.

If we already checked the user access permissions on the original open,
then don't bother checking again on recovery. Doing so can cause a
deadlock with NFSv4.1, since the may_open() operation is not privileged.
Furthermore, we can't report an access permission failure here anyway.

The seconds field of an nfstime4 structure is 64bit, but we are assuming
that the first 32bits are zero-filled. So if the client tries to set
atime to a value before the epoch (touch -t 196001010101), then the
server will save the wrong value on disk.

When we're doing open-by-filehandle in NFSv4.1, we shouldn't need to
do the cache consistency revalidation on the directory. It is
therefore more efficient to just use open_noattr, which returns the
file attributes, but not the directory attributes.
