introduce two configs:
- hidden CONFIG_BPF to select eBPF interpreter that classic socket filters
depend on
- visible CONFIG_BPF_SYSCALL (default off) that tracing and sockets can use
that solves several problems:
- tracing and others that wish to use eBPF don't need to depend on NET.
They can use BPF_SYSCALL to allow loading from userspace or select BPF
to use it directly from kernel in NET-less configs.
- in 3.18 programs cannot be attached to events yet, so don't force it on
- when the rest of eBPF infra is there in 3.19+, it's still useful to
switch it off to minimize kernel size
bloat-o-meter on x64 shows:
add/remove: 0/60 grow/shrink: 0/2 up/down: 0/-15601 (-15601)
tested with many different config combinations. Hopefully didn't miss anything.

====================
cxgb4 : DCBx fixes for apps/host lldp agents
This patchset contains some minor fixes for cxgb4 DCBx code. Chiefly, cxgb4
was not cleaning up any apps added to kernel app table when link was lost.
Disabling DCBx in firmware would automatically set DCBx state to host-managed
and enabled, we now wait for an explicit enable call from an lldp agent instead
First patch was originally sent to net-next, but considering it applies to
correcting behaviour of code already in net, I think it qualifies as a bug fix.

Clear out any DCB apps we might have added to kernel table when we lose DCB
sync (or IEEE equivalent event). These were previously left behind and not
cleaned up correctly. IEEE allows individual components to work independently,
so improve check for IEEE completion by specifying individual components.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Allow to recycle a TCP port in conntrack when the change role from
server to client, from Marcelo Leitner.
2) Fix possible off by one access in ip_set_nfnl_get_byindex(), patch
from Dan Carpenter.
3) alloc_percpu returns NULL on error, no need for IS_ERR() in nf_tables
chain statistic updates. From Sabrina Dubroca.
4) Don't compile ip options in bridge netfilter, this mangles the packet
and bridge should not alter layer >= 3 headers when forwarding packets.
Patch from Herbert Xu and tested by Florian Westphal.
5) Account the final NLMSG_DONE message when calculating the size of the
nflog netlink batches. Patch from Florian Westphal.
6) Fix a possible netlink attribute length overflow with large packets.
Again from Florian Westphal.
7) Release the skbuff if nfnetlink_log fails to put the final
NLMSG_DONE message. This fixes a leak on error. This shouldn't ever
happen though, otherwise this means we miscalculate the netlink batch
size, so spot a warning if this ever happens so we can track down the
problem. This patch from Houcheng Lin.
8) Look at the right list when recycling targets in the nft_compat,
patch from Arturo Borrero.

Commit 34e5a5273d6aa0ee ("cpufreq: cpufreq-dt: extend with
platform_data") changed cpufreq_init() to only call
cpumask_setall(policy->cpus) if the platform data indicates that all
CPUs share the same clock. Before, cpufreq_generic_init() did this
unconditionally.
This causes a crash on r8a7791/koelsch when resuming from s2ram:

If we couldn't find our extent item, we accessed the current slot
(path->slots[0]) to check if it corresponds to an equivalent skinny
metadata item. However this slot could be beyond our last item in the
leaf (i.e. path->slots[0] >= btrfs_header_nritems(leaf)), in which case
we shouldn't process it.
Since btrfs_lookup_extent() is only used to find extent items for data
extents, fix this by removing completely the logic that looks up for an
equivalent skinny metadata item, since it can not exist.

If an asynchronous suspend_late or freeze_late callback fails
during the SUSPEND, FREEZE or QUIESCE phases, we don't propagate the
corresponding error correctly, in effect ignoring the error and
continuing the suspend-to-ram/hibernation. During suspend-to-ram this
could leave some devices without a valid saved context, leading to a
failure to reinitialize them during resume. During hibernation this
could leave some devices active interfeering with the creation /
restoration of the hibernation image. Also this could leave the
corresponding devices without a valid saved context and failure to
reinitialize them during resume.

Commit 6ab3430129e2 ("mfd: Add ACPI support") made the MFD subdevices
share the parent MFD ACPI companion if no _HID/_CID is specified for
the subdevice in mfd_cell description. However, since all the subdevices
share the ACPI companion, the match and modalias generation logic started
to use the ACPI companion as well resulting this:
# cat /sys/bus/platform/devices/HID-SENSOR-200041.6.auto/modalias
acpi:INT33D1:PNP0C50:
instead of the expected one
# cat /sys/bus/platform/devices/HID-SENSOR-200041.6.auto/modalias
platform:HID-SENSOR-200041
In other words the subdevice modalias is overwritten by the one taken from
ACPI companion. This causes udev not to load the driver anymore.
It is useful to be able to share the ACPI companion so that MFD subdevices
(and possibly other devices as well) can access the ACPI resources even if
they do not have ACPI representation in the namespace themselves.
An example where this is used is Minnowboard LPC driver that creates GPIO
as a subdevice among other things. Without the ACPI companion gpiolib is
not able to lookup the corresponding GPIO controller from ACPI GpioIo
resource.
To fix this, restrict the match and modalias logic to be limited to the
first (primary) physical device associated with the given ACPI comapnion.
The secondary devices will still be able to access the ACPI companion,
but they will be matched in a different way.

These should not be accessed outside driver, thus removed the APIs
from the header file and made the implementation static.

Moved the implementation from am33xx-restart.c to the prm33xx.c file to
isolate the PRM register accesses to be private for PRM driver.

These are not used for anything, so remove both the implementations and
header file references.

These shall not be accessed outside the CM driver. This also removes the
need for the cminst44xx.h header.

PRM driver now has a generic API for checking hardreset status. SoC
specific support functions are registered through the prm_ll_data.

Added support for prm_init for AM33xx SoC. This is needed to register
SoC specific prm_ll_data for these devices.

AM43xx is using OMAP4+ PRM driver, so it should be using the corresponding
hardreset ops from the hwmod also.

These are now identical with the OMAP4 implementations, so use the OMAP4
versions and remove the AM33xx ones.
