When out of memory and we can't add ctrl vq buffers,
probe fails. Unfortunately the error handling is
out of spec: it calls del_vqs without bothering
to reset the device first.
To fix, call the full cleanup function in this case.

Console driver is out of spec. The spec says:
A driver MUST NOT decrement the available idx on a live
virtqueue (ie. there is no way to “unexpose” buffers).
and it does exactly that by trying to detach unused buffers
without doing a device reset first.
Defer detaching the buffers until device unplug.
Of course this means we might get an interrupt for
a vq without an attached port now. Handle that by
discarding the consumed buffer.

Previous testcase redirects echo-out into /dev/null
using "&>" as below
echo "trigger-command" >> trigger &> /dev/null
But this means redirecting both stdout and stderr into
/dev/null because it is same as below
echo "trigger-command" >> trigger > /dev/null 2>&1
So ">> trigger" redirects stdout to trigger file, but
next "> /dev/null" redirects stdout to /dev/null again
and the last "2>/&1" redirects stderr to stdout (/dev/null)
This fixes it by "2> /dev/null". And also, since it
must fail, add "!" to echo command.

File /sys/kernel/debug/kprobes/blacklist displays random addresses:

0x0000000047149a90-0x00000000bfcb099a print_type_x8

This breaks 'perf probe' which uses the blacklist file to prohibit
probes on certain functions by checking the address range.
Fix this by printing the correct (unhashed) address.
The file mode is read all but this is not an issue as the file
hierarchy points out:

Everything in and below /sys/kernel/debug is rwx to root only,

Background:
Directory /sys/kernel/debug/kprobes is created by debugfs_create_dir()

Arnaldo noticed that the latest kernel is missing the syscall event system
directory in x86. I bisected it down to d5a00528b5 ("syscalls/core,
syscalls/x86: Rename struct pt_regs-based sys_*() to __x64_sys_*()").
The system call trace events are special, as there is only one trace event
for all system calls (the raw_syscalls). But a macro that wraps the system
calls creates meta data for them that copies the name to find the system
call that maps to the system call table (the number). At boot up, it does a
kallsyms lookup of the system call table to find the function that maps to
the meta data of the system call. If it does not find a function, then that
system call is ignored.
Because the x86 system calls had "__x64_", or "__ia32_" prefixed to the
"sys" for the names, they do not match the default compare algorithm. As
this was a problem for power pc, the algorithm can be overwritten by the
architecture. The solution is to have x86 have its own algorithm to do the
compare and this brings back the system call trace events.

Commit 5928c28152 (ACPI / video: Default lcd_only to true on Win8-ready
and newer machines) made only_lcd default to true on all machines where
acpi_osi_is_win8() returns true, including laptops.
The purpose of this is to avoid the bogus / non-working acpi backlight
interface which many newer BIOS-es define on desktop machines.
But this is causing a regression on some laptops, specifically on the
Dell XPS 13 2013 model, which does not have the LCD flag set for its
fully functional ACPI backlight interface.
Rather then DMI quirking our way out of this, this commits changes the
logic for setting only_lcd to true, to only do this on machines with
a desktop (or server) dmi chassis-type.
Note that we cannot simply only check the chassis-type and not register
the backlight interface based on that as there are some laptops and
tablets which have their chassis-type set to "3" aka desktop. Hopefully
the combination of checking the LCD flag, but only on devices with
a desktop(ish) chassis-type will avoid the needs for DMI quirks for this,
or at least limit the amount of DMI quirks which we need to a minimum.

Intel Wired LAN Driver Updates 2018-04-24
This series contains fixes to ixgbevf, igb and ice drivers.
Colin Ian King fixes the return value on error for the new XDP support
that went into ixgbevf for 4.17.
Vinicius provides a fix for queue 0 for igb, which was not receiving all
the credits it needed when QAV mode was enabled.
Anirudh provides several fixes for the new ice driver, starting with
properly initializing num_nodes_added to zero. Fixed up a code comment
to better reflect what is really going on in the code. Fixed how to
detect if an OICR interrupt has occurred to a more reliable method.
Md Fahad fixes the ice driver to allocate the right amount of memory
when reading and storing the devices MAC addresses. The device can have
up to 2 MAC addresses (LAN and WoL), while WoL is currently not
supported, we need to ensure it can be properly handled when support is
added.

been added. Note that the WoL MAC address is ignored currently as the WoL
