This patch modifies the device name as devfreq(X) for sysfs by using the 'devfreq'
prefix word instead of separate device name. On user-space aspect, user would
find the some devfreq drvier with 'devfreq(X)' pattern. So, this patch modify the
device name as following:
- /sys/class/devfreq/[non-standard device name] -> /sys/class/devfreq/devfreq(X)

This patch just removes '.' character from the sysfs name of devfreq-event
device as following. Usually, the subsystem uses the similiar naming style
such as {framework name}{Number}.
- old : /sys/class/devfreq-event/event.(X)
- new : /sys/class/devfreq-event/event(X)
And this patch initializes the value of 'event_no' with -1
in order to remove the unneeded operation (-1) when calling
the atomic_inc_return(&event_no).
Lastly, this patch adds the ABI document for devfreq-event class.

CONFIG_DEBUG_NX_TEST has been broken since CONFIG_DEBUG_SET_MODULE_RONX=y
was added in v2.6.37 via:
84e1c6bb38eb ("x86: Add RO/NX protection for loadable kernel modules")
since the exception table was then made read-only.
Additionally, the manually constructed extables were never fixed when
relative extables were introduced in v3.5 via:
706276543b69 ("x86, extable: Switch to relative exception table entries")
However, relative extables won't work for test_nx.c, since test instruction
memory areas may be more than INT_MAX away from an executable fixup
(e.g. stack and heap too far away from executable memory with the fixup).
Since clearly no one has been using this code for a while now, and similar
tests exist in LKDTM, this should just be removed entirely.

The 'userspace' governor adds a sysfs entry, which is removed when
the governor is changed, or the devfreq device is released. However,
when the latter occurs via device_unregister(), device_del() is
called first, which removes the sysfs entries recursively and deletes
the kobject.
This means we get an Oops when the governor calls
sysfs_remove_group() on the deleted kobject. Fix this by only doing
the call when kobj *hasn't* been kobject_del()'d.
Note that we can't just remove the call to sysfs_remove_group()
entirely - it's needed for when the governor is changed to one which
doesn't need a sysfs entry.

Liam R. Howlett says:
====================
sparc64: Recover from userspace non-resumable PIO & MEM errors
A non-resumable error from userspace is able to cause a kernel panic or trap
loop due to the setup and handling of the queued traps once in the kernel.
This patch series addresses both of these issues.
The queues are fixed by simply zeroing the memory before use.
PIO errors from userspace will result in a SIGBUS being sent to the user
process.
The MEM errors form userspace will result in a SIGKILL and also cause the
offending pages to be claimed so they are no longer used in future tasks.
SIGKILL is used to ensure that the process does not try to coredump and result
in an attempt to read the memory again from within kernel space. Although
there is a HV call to scrub the memory (mem_scrub), there is no easy way to
guarantee that the real memory address(es) are not used by other tasks.
Clearing the error with mem_scrub would zero the memory and cause the other
processes to proceed with bad data.
The handling of other non-resumable errors remain unchanged and will cause a
panic.

User processes trying to access an invalid memory address via PIO will

Error queues use a non-zero first word to detect if the queues are full.
Using pages that have not been zeroed may result in false positive
overflow events. These queues are set up once during boot so zeroing
all mondo and error queue pages is safe.
Note that the false positive overflow does not always occur because the
page allocation for these queues is so early in the boot cycle that
higher number CPUs get fresh pages. It is only when traps are serviced
with lower number CPUs who were given already used pages that this issue
is exposed.

When matching on the ICMPv6 code ICMPV6_CODE rather than

tc filter add dev eth0 protocol ipv6 parent ffff: flower \
indev eth0 ip_proto icmpv6 type 128 code 0 action drop
Without this change the code parameter above is effectively ignored.

Some Hypervisors detach VFs from VMs by instantly causing an FLR event
to be generated for a VF.
In the mlx4 case, this will cause that VF's comm channel to be disabled
before the VM has an opportunity to invoke the VF device's "shutdown"
method.
The result is that the VF driver on the VM will experience a command
timeout during the shutdown process when the Hypervisor does not deliver
a command-completion event to the VM.
To avoid FW command timeouts on the VM when the driver's shutdown method
is invoked, we detect the absence of the VF's comm channel at the very
start of the shutdown process. If the comm-channel has already been
disabled, we cause all FW commands during the device shutdown process to
immediately return success (and thus avoid all command timeouts).
