get_user() and put_user() are inline functions in the meantime
again. Both will generate the mvcos instruction if compiled
with -march=z10 (or greater).
The kernel parameter "uaccess_primary" can only change the behavior
of out-of-line uaccess functions like copy_from_user() to not use
the mvcos instruction, but not for the above named inlined functions.
Therefore it is quite useless and the parameter can be removed.

This patch removes TP3 support on CHV since there is no support
for HBR2 on this platform.
v2: rename the function to indicate it checks source rates (Jani)

Remove the two facility bits
50 - constrained transactional-execution facility
74 - transactional-execution facility
from the required facilities if the kernel is built with -march=zEC12.
E.g. z/VM 6.3 doesn't virtualize the TX facility yet. Therefore a kernel
built with -march=zEC12 and ipl'ed on a zEC12 machine as a z/VM 6.3 guest
will emit a message about the missing facilities and stop working.
The kernel however doesn't make use of the TX facility, therefore remove
the two TX related facility bits and fix this unpleasant behavior.

By accident this level has been removed by the NUMA infrastructure patch.
For non-NUMA systems with CPUs that span more than one book, this makes
the scheduler only use one of the books and the other books remain idle.
Fix this and re-add the missing level.
For NUMA and non-NUMA we have the following scheduling domains and groups:
- SMT (Groups: CPU threads)
- MC (Groups: Cores)
- BOOK (Groups: Books)
For the non-NUMA case we have one last level scheduling domain:
- DIE (Groups: Whole system, has all CPUs -> cpu_cpu_mask)
For the NUMA case we have the following two last level scheduling domains:
- DIE (Groups: NUMA nodes -> cpu_cpu_mask -> returns node siblings)
- NUMA (Groups: Whole system, has all CPUs -> created in sched_init_numa())

drm/i915: Allow parsing of variable size child device entries from VBT
That commit is not valid for v4.2, however it will be valid for v4.3. It
was simply queued too early.
The referenced regressing commit is just fine until the size of struct
common_child_dev_config changes, and that won't happen until
v4.3. Indeed, the expected size checks here rely on the increased size
of the struct, breaking new platforms.

REPORT LUNS should not fail just because the allocation length is less
than 16. The relevant section of SPC-4 is:
4.2.5.6 Allocation length
The ALLOCATION LENGTH field specifies the maximum number of bytes or
blocks that an application client has allocated in the Data-In
Buffer. The ALLOCATION LENGTH field specifies bytes unless a
different requirement is stated in the command definition.
An allocation length of zero specifies that no data shall be
transferred. This condition shall not be considered an error.
So we should just truncate our response rather than return an error.

The object tt_local is allocated with kmalloc and not initialized when the
function batadv_tt_local_add checks for the vlan. But this function can
only cleanup the object when the (not yet initialized) reference counter of
the object is 1. This is unlikely and thus the object would leak when the
vlan could not be found.
Instead the uninitialized object tt_local has to be freed manually and the
pointer has to set to NULL to avoid calling the function which would try to
decrement the reference counter of the not existing object.

It was reported that after 10-20 reboots, a usb keyboard plugged
into a docking station would not work unless it was replugged in.
Using usbmon, it turns out the interrupt URBs were streaming with
callback errors of -71 for some reason. The hid-core.c::hid_io_error was
supposed to retry and then reset, but the reset wasn't really happening.
The check for HID_NO_BANDWIDTH was inverted. Fix was simple.

could recreate a stream of errors but no disconnect.

A value of 2560 (1280k) will accommodate a 10-data-disk stripe
write with chunk size 128k. In the testing I've done using
iozone, fio, and aio-stress across a number of different storage
devices, a value of 1280 does not show a big performance
difference from 512, but will hopefully help software RAID
setups using SATA disks, as reported by Christoph.
NOTE: drivers/block/aoe/aoeblk.c sets its own max_hw_sectors_kb to
BLK_DEF_MAX_SECTORS. So, this patch essentially changes aeoblk to
Use a larger maximum sector size, and I did not test this.

This reverts commit 34b48db66e08ca1c1bc07cf305d672ac940268dc.
That commit caused performance regressions for streaming I/O
workloads on a number of different storage devices, from
SATA disks to external RAID arrays. It also managed to
trip up some buggy firmware in at least one drive, causing
data corruption.
The next patch will bump the default max_sectors_kb value to
1280, which will accommodate a 10-data-disk stripe write
with chunk size 128k. In the testing I've done using iozone,
fio, and aio-stress, a value of 1280 does not show a big
performance difference from 512. This will hopefully still
help the software RAID setup that Christoph saw the original
performance gains with while still not regressing other
storage configurations.

The scanner (here DS3508) always returns 64 bytes per urb buffer. The first
byte indicates the data length used in the current buffer. There even was
a comment describing this. But the comment also said that we'll send
everything in the buffer to the tty layer. That means sending the actual
barcode data and lots of trailing zeroes. This patch lets the driver only
send the real data.

The driver used usb_get_serial_data(port->serial) which compiled but resulted
in a NULL pointer being returned (and subsequently used). I did not go deeper
into this but I guess this is a regression.

The current code prints all wMaxPacketSize content at endpoint
descriptor, if there is a high speed, high bandwidth endpoint,
it may confuse the users, eg, if there are 3 transactions during
microframe, it will print "wMaxPacket 1400" for packet content.
This commit splits wMaxpacketSize and transaction numbers for
output messages.

The ehci platform device's drvdata is the pointer of struct usb_hcd
already, so we doesn't need to call bus_to_hcd conversion again.
