Pull xen cleanup from Juergen Gross:
"One cleanup to remove VLAs from the kernel"

x86/xen: Remove use of VLAs

Proxying the cpuif accesses at EL2 makes use of vcpu_data_guest_to_host
and co, which check the endianness, which call into vcpu_read_sys_reg...
which isn't mapped at EL2 (it was inlined before, and got moved OoL
with the VHE optimizations).
The result is of course a nice panic. Let's add some specialized
cruft to keep the broken platforms that require this hack alive.
But, this code used vcpu_data_guest_to_host(), which expected us to
write the value to host memory, instead we have trapped the guest's
read or write to an mmio-device, and are about to replay it using the
host's readl()/writel() which also perform swabbing based on the host
endianness. This goes wrong when both host and guest are big-endian,
as readl()/writel() will undo the guest's swabbing, causing the
big-endian value to be written to device-memory.
What needs doing?
A big-endian guest will have pre-swabbed data before storing, undo this.
If its necessary for the host, writel() will re-swab it.
For a read a big-endian guest expects to swab the data after the load.
The hosts's readl() will correct for host endianness, giving us the
device-memory's value in the register. For a big-endian guest, swab it
as if we'd only done the load.
For a little-endian guest, nothing needs doing as readl()/writel() leave
the correct device-memory value in registers.
Tested on Juno with that rarest of things: a big-endian 64K host.
Based on a patch from Marc Zyngier.

A typo in kvm_vcpu_set_be()'s call:
| vcpu_write_sys_reg(vcpu, SCTLR_EL1, sctlr)
causes us to use the 32bit register value as an index into the sys_reg[]
array, and sail off the end of the linear map when we try to bring up
big-endian secondaries.

On the quest to remove all VLAs from the kernel[1], this avoids VLAs
in dm-raid1.c by just using the maximum size for the stack arrays.
The nr_mirrors value was already capped at 9, so this makes it a trivial
adjustment to the array sizes.

We have check if queue is not empty when start flushing queues on
by mac80211 callback, but we also can start flushing queues by internal
driver calls. So move check into rt2x00queue_flush_queue() to assure
we do not flush empty queue anytime.
Additionally add warning if we start to kick empty queue as in such
situation we set wrong index in the HW queue, what can confuse the HW
and have various negative consequences.

There are quite a few code snippet like the following in verifier:
subprog_start = 0;
if (env->subprog_cnt == cur_subprog + 1)
subprog_end = insn_cnt;
else
subprog_end = env->subprog_info[cur_subprog + 1].start;
The reason is there is no marker in subprog_info array to tell the end of
it.
We could resolve this issue by introducing a faked "ending" subprog.
The special "ending" subprog is with "insn_cnt" as start offset, so it is
serving as the end mark whenever we iterate over all subprogs.

Currently, verifier treat main prog and subprog differently. All subprogs
detected are kept in env->subprog_starts while main prog is not kept there.
Instead, main prog is implicitly defined as the prog start at 0.
There is actually no difference between main prog and subprog, it is better
to unify them, and register all progs detected into env->subprog_starts.
This could also help simplifying some code logic.

Commit 7ed1c1901fe5 (tools: fix cross-compile var clobbering) removed
setting of LD to $(CROSS_COMPILE)gcc. This broke build of acpica
(acpidump) in power/acpi:
ld: unrecognized option '-D_LINUX'
The tools pass CFLAGS to the linker (incl. -D_LINUX), so revert this
particular change and let LD be $(CC) again. Note that the old behaviour
was a bit different, it used $(CROSS_COMPILE)gcc which was eliminated by
the commit 7ed1c1901fe5. We use $(CC) for that reason.

One layout supported by the Marvell NAND controller supports NAND pages
of 2048 bytes, all handled in one single chunk when using BCH with a
strength of 4-bit per 512 bytes. In this case, instead of the generic
XTYPE_WRITE_DISPATCH/XTYPE_LAST_NAKED_RW couple, the controller expects
to receive XTYPE_MONOLITHIC_RW.
This fixes problems at boot like:

struct xfrm_state is rather large (768 bytes here) and therefore wastes
quite a lot of memory as it falls into the kmalloc-1024 slab cache,
leaving 256 bytes of unused memory per XFRM state object -- a net waste
of 25%.
Using a dedicated slab cache for struct xfrm_state reduces the level of
internal fragmentation to a minimum.
On my configuration SLUB chooses to create a slab cache covering 4
pages holding 21 objects, resulting in an average memory waste of ~13
bytes per object -- a net waste of only 1.6%.
In my tests this led to memory savings of roughly 2.3MB for 10k XFRM
states.

This set simplifies BPF JITs significantly by moving ld_abs/ld_ind

is in patch 'implement ld_abs/ld_ind in native bpf'. Thanks!
v1 -> v2:
- Added missing seen_lds_abs in LDX_MSH and use X = A
initially due to being preserved on func call.
- Added a large batch of cBPF tests into test_bpf.
- Added x32 removal of LD_ABS/LD_IND, so all JITs are

a slow-path helper, we can get rid of the complexity from x32 JIT.
