Prior to the existance of 64-bit backends using the X86_64 ABI,
frontends used the X86_32 ABI. These old frontends do not specify the
ABI and when used with a 64-bit backend do not work.
On x86, default to the X86_32 ABI if one is not specified. Backends
on ARM continue to default to their NATIVE ABI.

Current migration code uses blk_put_request in order to finish a request
before requeuing it. This function doesn't update the statistics of the
queue, which completely screws accounting. Use blk_end_request_all instead
which properly updates the statistics of the queue.

Currently the binary hypfs interfaces provides new data only once within
an interval time of one second. This patch removes this restriction and
now new data is returned immediately on every read on a hypfs binary file.
This is done in order to allow more consistent snapshots for programs
that read multiple hypfs binary files.

With this feature, you can read the CPU performance metrics provided by the
z/VM diagnose 0C. This then allows to get the management time for each
online CPU of the guest where the diagnose is executed.
The new debugfs file /sys/kernel/debug/s390_hypfs/diag_0c exports the
diag0C binary data to user space via an open/read/close interface.
The binary data consists out of a header structure followed by an
array that contains the diagnose 0c data for each online CPU.

As already demonstrated with PCI [1] and the platform bus [2], a
driver_override property in sysfs can be used to bypass the id
matching of a device to a AMBA driver. This can be used by VFIO to
bind to any AMBA device requested by the user.

The __asmeq macro is used inside inline asm statements to ensure that
register asm variables that explicitly specify a register are mapped
correctly onto those registers when used in inline asm input and output
constraints. However, the string based matching fails to take into
account that 'fp' is often referred to as 'r11' and 'ip' is often
referred to as 'r12', (e.g., by clang), causing false negatives.
Fix this by making __asmeq consider the ("fp","r11"), ("r11","fp"),
("ip","r12") and ("r12","ip") cases specifically.

show_cacheinfo() needs to access the cacheinfo structure of any online
cpu. This was done with using smp_processor_id() as in index while in
preemtible context.
This means the cpu could be offline and the data be gone when it would
be accessed.
Better use any online cpu address and protect the data by get_online_cpus()
and put_online_cpus().

CS node is recognized as a sign in UBIFS log replay mechanism.
Log relaying during mount should find the CS node in log head
at beginning and then replay the following uncommitted buds.
Here is a bug in log replay path: If the log head, which is
indicated by @log_lnum in mst_node, is empty, current UBIFS
replay nothing and directly mount the partition without any
warning. This action will put filesystem in an abnormal state,
e.g. space management in LPT area is incorrect to the real
space usage in main area.
We reproduced this bug by fault injection: turn log head leb
into all 0xFF. UBIFS driver mount the polluted partition
normally. But errors occur while running fs_stress on this
mount:
[89068.055183] UBI error: ubi_io_read: error -74 (ECC error) while reading 59 bytes from PEB 711:33088, read 59 bytes
[89068.179877] UBIFS error (pid 10517): ubifs_check_node: bad magic 0x101031, expected 0x6101831
[89068.179882] UBIFS error (pid 10517): ubifs_check_node: bad node at LEB 591:28992
[89068.179891] Not a node, first 24 bytes:
[89068.179892] 00000000: 31 10 10 00 37 84 64 04 10 04 00 00 00 00 00 00 20 00 00 00 02 01 00 00 1...7.d......... .......
[89068.180282] UBIFS error (pid 10517): ubifs_read_node: expected node type 2
This patch fix the problem by checking *lnum* to guarantee
the empty leb is not log head leb and return an error if the
log head leb is incorrectly empty. After this, we could catch
*log head empty* error in place.

Replaced previously open-coded Package C-state Limit decoding
with table-driven decoding. In doing so, updated to match January 2015
"Intel(R) 64 and IA-23 Architectures Software Developer's Manual".
In the past, turbostat would print package C-state residency columns
for all package states supported by the model's architecture, even though
a particular SKU may not support them, or they may be disabled by the BIOS.
Now turbostat will skip printing colunns if MSRs indicate that they are not enabled.
eg. many SKUs don't support PC7, and so that column will no longer be printed.

Some Toshiba laptops do not come with the ECO led installed, however,
the driver is registering support for it when it should not.
This patch makes the toshiba_eco_mode_available function more robust
in detecting ECO led capabilities, not registering the led on laptops
that do not support it and registering the led when it really does.
The ECO led function now returns 0x8e00 (Not Installed) by querying
with in[3] = 0, whenever theres no physical LED installed, and
returning 0x8300 (Input Data Error) when it is, however, there are
some BIOSes that have stub function calls not returning anything and
and the LED device was being registered too, hence the change of the
default return value from 1 to 0.

Packetization Layer Path MTU Discovery works separately beside
Path MTU Discovery at IP level, different net namespace has
various requirements on which one to chose, e.g., a virutalized
container instance would require TCP PMTU to probe an usable
effective mtu for underlying tunnel, while the host would
employ classical ICMP based PMTU to function.
Hence making TCP PMTU mechanism per net namespace to decouple
two functionality. Furthermore the probe base MSS should also
be configured separately for each namespace.
