There was a overlap between the snd_soc_codec_set_cache_io() cleanup and the
addition of the sirf-audio-codec resulting in the sirf-audio-codec driver still
using the old signature of snd_soc_codec_set_cache_io(), which will cause a
compile error. Since the core is able to automatically setup IO for this driver
we can just remove both the snd_soc_set_cache_io() call and the control_data
assignment.

master->max_speed_hz
When xfer->speed_hz is greater than master->max_speed_hz, it's generally safe
to use master->max_speed_hz as transfer speed.
Thus use master->max_speed_hz as transfer speed rather than return error when
xfer->speed_hz > master->max_speed_hz.

Commit 597ce1723e0f "MIPS: Support for 64-bit FP with O32 binaries"
introduced support for setting Status.FR=1 for O32 binaries with the
EF_MIPS_FP64 ELF header flag set. Whilst this flag is currently
supported by binutils it does introduce an ABI break within userland.
Objects built with EF_MIPS_FP64 cannot be safely linked with those built
without it since code in either object may assume behaviour specific to
a value of FR.
More recently there has been discussion around avoiding further
fragmentation of the O32 ABI whilst still allowing the use of FR=1 and
features such as MSA which depend upon it. Details of the plan to allow
this are still being worked on, and whilst the kernel will need the
ability to handle FR=1 with O32 tasks it is unclear what else it may
need to provide to a userland which seeks to avoid another ABI break. In
order to prevent the proliferation of userland which may rely upon the
current EF_MIPS_FP64 behaviour this patch marks the kernel support for
it experimental & disables it by default. Under current proposals it is
likely that this support can simply be enabled again later, but possibly
after the introduction of further interfaces with userland and support
for the MIPS R5 UFR feature.

Limit the number of bits to the maximum number of cpus a machine
can have.
possible_cpu_mask typically will have more bits set than a machine
may physically have. This results in wasted memory during per-cpu
memory allocations, if the possible mask contains more cpus than
physically possible for a given configuration.

In 32-bit mode, the start address passed to flush_icache_range is
shifted by 4 bytes before the second safe_store_code() call.
This causes system crash from time to time because the first 4 bytes
might not be flushed properly. This bug exists since linux-3.8.
Also remove obsoleted comment while at it.

The syscall_get_arguments function expects the arguments to be copied
to the '*args' argument but instead a local variable was used to hold
the system call argument. As a result of which, this variable was
never passed to the filter and any filter testing the system call
arguments would fail. This is fixed by passing the '*args' variable
as the destination memory for the system call arguments.

When doing nested virtualization, we may be able to read BNDCFGS but
still not be allowed to write to GUEST_BNDCFGS in the VMCS. Guard
writes to the field with vmx_mpx_supported(), and similarly hide the
MSR from userspace if the processor does not support the field.
We could work around this with the generic MSR save/load machinery,
but there is only a limited number of MSR save/load slots and it is
not really worthwhile to waste one for a scenario that should not
happen except in the nested virtualization case.

This is simple to do, the "host" BNDCFGS is either 0 or the guest value.
However, both controls have to be present. We cannot provide MPX if
we only have one of the "load BNDCFGS" or "clear BNDCFGS" controls.

XSAVE support for KVM is already using host_xcr0 & KVM_SUPPORTED_XCR0 as
a "dynamic" version of KVM_SUPPORTED_XCR0.
However, this is not enough because the MPX bits should not be presented
to the guest unless kvm_x86_ops confirms the support. So, replace all
instances of host_xcr0 & KVM_SUPPORTED_XCR0 with a new function
kvm_supported_xcr0() that also has this check.
Note that here:
if (xstate_bv & ~KVM_SUPPORTED_XCR0)
return -EINVAL;
if (xstate_bv & ~host_cr0)
return -EINVAL;
the code is equivalent to
if ((xstate_bv & ~KVM_SUPPORTED_XCR0) ||
(xstate_bv & ~host_cr0)
return -EINVAL;
i.e. "xstate_bv & (~KVM_SUPPORTED_XCR0 | ~host_cr0)" which is in turn
equal to "xstate_bv & ~(KVM_SUPPORTED_XCR0 & host_cr0)". So we should
also use the new function there.

With current match design every invocation of the connlimit_match
function means we have to perform (number_of_conntracks % 256) lookups
in the conntrack table [ to perform GC/delete stale entries ].
This is also the reason why ____nf_conntrack_find() in perf top has
> 20% cpu time per core.
This patch changes the storage to rbtree which cuts down the number of
ct objects that need testing.
When looking up a new tuple, we only test the connections of the host
objects we visit while searching for the wanted host/network (or
the leaf we need to insert at).
The slot count is reduced to 32. Increasing slot count doesn't
speed up things much because of rbtree nature.
before patch (50kpps rx, 10kpps tx):
+ 20.95% ksoftirqd/0 [nf_conntrack] [k] ____nf_conntrack_find
+ 20.50% ksoftirqd/1 [nf_conntrack] [k] ____nf_conntrack_find
+ 20.27% ksoftirqd/2 [nf_conntrack] [k] ____nf_conntrack_find
+ 5.76% ksoftirqd/1 [nf_conntrack] [k] hash_conntrack_raw
+ 5.39% ksoftirqd/2 [nf_conntrack] [k] hash_conntrack_raw
+ 5.35% ksoftirqd/0 [nf_conntrack] [k] hash_conntrack_raw
after (90kpps, 51kpps tx):
+ 17.24% swapper [nf_conntrack] [k] ____nf_conntrack_find
+ 6.60% ksoftirqd/2 [nf_conntrack] [k] ____nf_conntrack_find
+ 2.73% swapper [nf_conntrack] [k] hash_conntrack_raw
+ 2.36% swapper [xt_connlimit] [k] count_tree
Obvious disadvantages to previous version are the increase in code
complexity and the increased memory cost.
