BMI160 is an Inertial Measurement Unit (IMU) which provides acceleration
and angular rate measurement. It also offers a secondary I2C interface
for connecting a magnetometer sensor (usually BMM160).
Current driver offers support for accelerometer and gyroscope readings
via sysfs or via buffer interface using an external trigger (e.g.
hrtimer). Data is retrieved from IMU via I2C or SPI interface.
Datasheet is at:

Four instances of incorrect usage of non-static "inline" crept up
in arch/x86, all trivial; cleaning them up:
EVT_TO_HPET_DEV() - made static, it is only used in kernel/hpet.c
Debug version of check_iommu_entries() is an __init function.
Non-debug dummy empty version of it is declared "inline" instead -
which doesn't help to eliminate it (the caller is in a different unit,
inlining doesn't happen).
Switch to non-inlined __init function, which does eliminate it
(by discarding it as part of __init section).
crypto/sha-mb/sha1_mb.c: looks like they just forgot to add "static"
to their two internal inlines, which emitted two unused functions into
vmlinux.

error (as there is no PCI bus in these instances) on all NMIs:
NMI: PCI system error (SERR) for reason ff on CPU 0.

Fix the issue by overriding x86_platform.get_nmi_reason. Use 'booted on

There are several cases in compiled C code where a function may not
return at the end, and may instead fall through to the next function.
That may indicate a bug in the code, or a gcc bug, or even an objtool
bug. But in each case, objtool reports an unhelpful warning, something
like:
drivers/scsi/qla2xxx/qla_attr.o: warning: objtool: qla2x00_get_fc_host_stats()+0x0: duplicate frame pointer save
drivers/scsi/qla2xxx/qla_attr.o: warning: objtool: qla2x00_get_fc_host_stats()+0x0: frame pointer state mismatch
Detect this situation and print a more useful error message:
drivers/scsi/qla2xxx/qla_attr.o: warning: objtool: qla2x00_get_host_fabric_name() falls through to next function qla2x00_get_starget_node_name()
Also add some information about this warning and its potential causes to
the documentation.

When __vlan_insert_tag() fails from skb_vlan_push() path due to the
skb_cow_head(), we need to undo the __skb_push() in the error path
as well that was done earlier to move skb->data pointer to mac header.
Moreover, I noticed that when in the non-error path the __skb_pull()
is done and the original offset to mac header was non-zero, we fixup
from a wrong skb->data offset in the checksum complete processing.
So the skb_postpush_rcsum() really needs to be done before __skb_pull()
where skb->data still points to the mac header start and thus operates
under the same conditions as in __vlan_insert_tag().

The OMAP Platform code provides possibility to select GP Timer as
default clocksource instead of counter_32K by using bootcmd parameter
'clocksource', but the system will crash during early boot when this
option is used on dra7 or omap5 platforms, because it will hit BUG()
statement:
omap2_gptimer_clocksource_init
->BUG_ON(res);
This happens because clk_dev alias "sys_clkin_ck" is not registered.
Hence, fix it by adding missing "sys_clkin_ck" clk_dev aliases
definitions for omap5 and dra7.
