When running function tracing on a Linux guest running on VMware
Workstation, the guest would crash. This is due to tracing of the
sched_clock internal call of the VMware vmware_sched_clock(), which
causes an infinite recursion within the tracing code (clock calls must
not be traced).
Make vmware_sched_clock() not traced by ftrace.

According to Ted Ts'o ext4_getblk() called in ext4_xattr_inode_write()
should not return bh = NULL
The only time that bh could be NULL, then, would be in the case of
something really going wrong; a programming error elsewhere (perhaps a
wild pointer dereference) or I/O error causing on-disk file system
corruption (although that would be highly unlikely given that we had
*just* allocated the blocks and so the metadata blocks in question
probably would still be in the cache).

Currently the size of hypercall buffers allocated via
/dev/xen/hypercall is limited to a default of 64 memory pages. For live
migration of guests this might be too small as the page dirty bitmask
needs to be sized according to the size of the guest. This means
migrating a 8GB sized guest is already exhausting the default buffer
size for the dirty bitmap.
There is no sensible way to set a sane limit, so just remove it
completely. The device node's usage is limited to root anyway, so there
is no additional DOS scenario added by allowing unlimited buffers.
While at it make the error path for the -ENOMEM case a little bit
cleaner by setting n_pages to the number of successfully allocated
pages instead of the target size.

Commit a856531951dc80 ("xen: make xen_qlock_wait() nestable")
introduced a regression for Xen guests running fully virtualized
(HVM or PVH mode). The Xen hypervisor wouldn't return from the poll
hypercall with interrupts disabled in case of an interrupt (for PV
guests it does).
So instead of disabling interrupts in xen_qlock_wait() use a nesting
counter to avoid calling xen_clear_irq_pending() in case
xen_qlock_wait() is nested.

Commit 9da3f2b7405440 ("x86/fault: BUG() when uaccess helpers fault on
kernel addresses") introduced a regression for booting Xen PV guests.
Xen PV guests are using __put_user() and __get_user() for accessing the
p2m map (physical to machine frame number map) as accesses might fail
in case of not populated areas of the map.
With above commit using __put_user() and __get_user() for accessing
kernel pages is no longer valid. So replace the Xen hack by adding
appropriate p2m access functions using the default fixup handler.

====================
nfp: abm: move code and improve parameter validation
This set starts by separating Qdisc handling code into a new file.
Next two patches allow early access to TLV-based capabilities during
probe, previously the capabilities were parsed just before netdevs
were registered, but its cleaner to do some basic validation earlier
and avoid cleanup work.
Next three patches improve RED's parameter validation. First we provide
a more precise message about why offload failed (and move the parameter
validation to a helper). Next we make sure we don't set the top bit
in the 32 bit max RED threshold value. Because FW is treating the value
as signed it reportedly causes slow downs (unnecessary queuing and
marking) when top bit is set with recent firmwares. Last (and perhaps
least importantly) we offload the harddrop parameter of the Qdisc.
We don't plan to offload harddrop RED, but it seems prudent to make
sure user didn't set that flag as device behaviour would have differed.

In certain cases initialization logic which follows allocation of
the vNIC structure may want to validate the capabilities of that vNIC.
This is easy before vNIC is initialized for normal capabilities which
are at fixed offsets in control memory, easy to locate and read, but
poses a challenge if the capabilities are in form of TLVs. Parse
the TLVs early on so other code can just access parsed info, instead
of having to do the parsing by itself.

net: ethernet: ti: cpsw: fix vlan mcast
The cpsw holds separate mcast entires for vlan entries. At this moment
driver adds only not vlan mcast addresses, omitting vlan/mcast entries.
As result mcast for vlans doesn't work. It can be fixed by adding same
mcast entries for every created vlan, but this patchseries uses more
sophisticated way and allows to create mcast entries only for vlans
that really require it. Generic functions from this series can be
reused for fixing vlan and macvlan unicast.
Simple example of ALE table before and after this series, having same
mcast entries as for vlan 100 as for real device (reserved vlan 2),
and one mcast address only for vlan 100 - 01:1b:19:00:00:00.

Here mcast entry (ptpl2), is added only for vlan 100
as it should be.

The vlan configuration is not restored after interface donw/up sequence
(if dual-emac - both interfaces). Tested on am572x EVM.
Steps to check:
~# ip link add link eth1 name eth1.100 type vlan id 100
~# ifconfig eth0 down
~# ifconfig eth1 down
Try to remove vid and observe warning:
~# ip link del eth1.100
[ 739.526757] net eth1: removing vlanid 100 from vlan filter
[ 739.533322] failed to kill vid 0081/100 for device eth1
This patch fixes it, restoring only vlan ALE entries and all other
unicast/multicast entries are restored by system calling rx_mode ndo.

At this moment, mcast addresses are added for real device only
(reserved vlans for dual-emac mode), even if a mcast address was added
for some vlan only, thus ALE doesn't have corresponding vlan mcast
entries after vlan socket joined multicast group. So ALE drops vlan
frames with mcast addresses intended for vlans and potentially can
receive mcast frames for base ndev. That's not correct. So, fix it by
creating only vlan/mcast entries as requested. Patch doesn't use any
additional lists and is based on device mc address list and cpsw ALE
table entries.

It's redundancy for the drivers to hold the list of vlans when
absolutely the same list exists in vlan core. In most cases it's
needed only to traverse the vlan devices, their vids and sync some
settings with h/w, so add API to simplify this.
At least some of these drivers also can benefit:

updates
In order to avoid all table update, and only remove or add new
address, the auxiliary function exists, named __hw_addr_sync_dev().
It allows end driver do nothing when nothing changed and add/rm when
concrete address is firstly added or lastly removed. But it doesn't
include cases when an address of real device or vlan was reused by
other vlans or vlan/macval devices.
For handaling events when address was reused/unreused the patch adds
new auxiliary routine - __hw_addr_ref_sync_dev(). It allows to do
nothing when nothing was changed and do updates only for an address
being added/reused/deleted/unreused. Thus, clone address changes for
vlans can be mirrored in the table. The function is exclusive with
__hw_addr_sync_dev(). It's responsibility of the end driver to
identify address vlan device, if it needs so.

The commit f77f0aee4da4 ("net: use core MTU range checking in USB NIC
drivers") introduce a common MTU handling for usbnet. But it's missing
the necessary changes for smsc95xx. So set the MTU range accordingly.
This patch has been tested on a Raspberry Pi 3.
