This is a rebased version of patch [0].
The 32 kHz reference clock on the i.MX6UL(L) can be output by
setting the external signal XTALOSC_REF_CLK_32K in one of the
following ways [1]:
|----------------------------------------------------------|
| Signal | Pad | Mode | Direction |

Before patch [2] the mux mode for the external reference clock was
missing. The patch named the mux mode as used in the NXP Linux
4.9.11_1.0.0 release, but the Reference Manual uses the name
OSC32K_32K_OUT, e.g. in [3].

instead.

- the instances were named sometimes SDn, sometimes SDHCn, whereas they
are named ESDHCn in the reference manual, e.g.:
MX25_PAD_SD1_CMD__SD1_CMD
MX25_PAD_D15__SDHC1_DAT7
- the data ports were named sometimes DATAn, sometimes DATn like in the
reference manual, e.g.:
MX25_PAD_SD1_DATA0__SD1_DATA0
MX25_PAD_D15__SDHC1_DAT7
- in one case, the clock port was named DAT_CLK instead of CLK:
MX25_PAD_CSI_D7__SDHC2_DAT_CLK
This change:
- introduces new definitions using the naming from the reference
manual,
- keeps definitions using the legacy naming in order not to break
compatibility for out-of-tree users (they can be removed later),
- updates the in-tree files that were using the legacy naming.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we

59f47eff03a0 ("powerpc/pci: Use of_irq_parse_and_map_pci() helper")
replaced of_irq_parse_pci() + irq_create_of_mapping() with
of_irq_parse_and_map_pci(), but neglected to capture the virq
returned by irq_create_of_mapping(), so virq remained zero, which
caused INTx configuration to fail.
Save the virq value returned by of_irq_parse_and_map_pci() and correct
the virq declaration to match the of_irq_parse_and_map_pci() signature.

Here the chunk size for INIT_ACK packet becomes too big, mostly
because of the state cookie (INIT packet has large size with
many address parameters), plus additional server parameters.
Later this chunk causes the panic in skb_put_data():
skb_packet_transmit()
sctp_packet_pack()
skb_put_data(nskb, chunk->skb->data, chunk->skb->len);
'nskb' (head skb) was previously allocated with packet->size
from u16 'chunk->chunk_hdr->length'.
As suggested by Marcelo we should check the chunk's length in
_sctp_make_chunk() before trying to allocate skb for it and
discard a chunk if its size bigger than SCTP_MAX_CHUNK_LEN.

s390/qeth: fix underestimated count of buffer elements
For a memory range/skb where the last byte falls onto a page boundary
(ie. 'end' is of the form xxx...xxx001), the PFN_UP() part of the
calculation currently doesn't round up to the next PFN due to an
off-by-one error.
Thus qeth believes that the skb occupies one page less than it
actually does, and may select a IO buffer that doesn't have enough spare
buffer elements to fit all of the skb's data.
HW detects this as a malformed buffer descriptor, and raises an
exception which then triggers device recovery.

net: stmmac: rename GMAC_INT_DEFAULT_MASK for dwmac4
GMAC_INT_DEFAULT_MASK is written to the interrupt enable register.
In previous versions of the IP (e.g. dwmac1000), this register was
instead an interrupt mask register.
To improve clarity and reflect reality, rename GMAC_INT_DEFAULT_MASK
to GMAC_INT_DEFAULT_ENABLE.

net: stmmac: discard disabled flags in interrupt status register
The interrupt status register in both dwmac1000 and dwmac4 ignores
interrupt enable (for dwmac4) / interrupt mask (for dwmac1000).
Therefore, if we want to check only the bits that can actually trigger
an irq, we have to filter the interrupt status register manually.
Commit
0a764db10337 ("stmmac: Discard masked flags in interrupt status
register") fixed this for dwmac1000. Fix the same issue for dwmac4.
Just like commit
0a764db10337 ("stmmac: Discard masked flags in
interrupt status register"), this makes sure that we do not get
spurious link up/link down prints.

ibmvnic: Reset long term map ID counter
When allocating RX or TX buffer pools, the driver needs to provide a
unique mapping ID to firmware for each pool. This value is assigned
using a counter which is incremented after a new pool is created. The
ID can be an integer ranging from 1-255. When migrating to a device
that requests a different number of queues, this value was not being
reset properly. As a result, after enough migrations, the counter
exceeded the upper bound and pool creation failed. This is fixed by
resetting the counter to one in this case.

Merge git://git./pub/scm/linux/kernel/git/bpf/bpf
Daniel Borkmann says:
====================
pull-request: bpf 2018-02-09
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Two fixes for BPF sockmap in order to break up circular map references
from programs attached to sockmap, and detaching related sockets in
case of socket close() event. For the latter we get rid of the
smap_state_change() and plug into ULP infrastructure, which will later
also be used for additional features anyway such as TX hooks. For the
second issue, dependency chain is broken up via map release callback
to free parse/verdict programs, all from John.
2) Fix a libbpf relocation issue that was found while implementing XDP
support for Suricata project. Issue was that when clang was invoked
with default target instead of bpf target, then various other e.g.
debugging relevant sections are added to the ELF file that contained
relocation entries pointing to non-BPF related sections which libbpf
trips over instead of skipping them. Test cases for libbpf are added
as well, from Jesper.
3) Various misc fixes for bpftool and one for libbpf: a small addition
to libbpf to make sure it recognizes all standard section prefixes.
Then, the Makefile in bpftool/Documentation is improved to explicitly
check for rst2man being installed on the system as we otherwise risk
installing empty man pages; the man page for bpftool-map is corrected
and a set of missing bash completions added in order to avoid shipping
bpftool where the completions are only partially working, from Quentin.
4) Fix applying the relocation to immediate load instructions in the
nfp JIT which were missing a shift, from Jakub.
5) Two fixes for the BPF kernel selftests: handle CONFIG_BPF_JIT_ALWAYS_ON=y
gracefully in test_bpf.ko module and mark them as FLAG_EXPECTED_FAIL
in this case; and explicitly delete the veth devices in the two tests
test_xdp_{meta,redirect}.sh before dismantling the netnses as when
selftests are run in batch mode, then workqueue to handle destruction
might not have finished yet and thus veth creation in next test under
same dev name would fail, from Yonghong.
6) Fix test_kmod.sh to check the test_bpf.ko module path before performing
an insmod, and fallback to modprobe. Especially the latter is useful
when having a device under test that has the modules installed instead,
from Naresh.

Merge branch 'for-linus' of git://git./linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens:
"The main thing in this merge is the defense for the Spectre
vulnerabilities. But there are other updates as well, the changes in
more detail:
- An s390 specific implementation of the array_index_mask_nospec
function to the defense against spectre v1
- Two patches to utilize the new PPA-12/PPA-13 instructions to run
the kernel and/or user space with reduced branch predicton.
- The s390 variant of the 'retpoline' spectre v2 defense called
'expoline'. There is no return instruction for s390, instead an
indirect branch is used for function return
The s390 defense mechanism for indirect branches works by using an
execute-type instruction with the indirect branch as the target of
the execute. In effect that turns off the prediction for the
indirect branch.
- Scrub registers in entry.S that contain user controlled values to
prevent the speculative use of these values.
- Re-add the second parameter for the s390 specific runtime
instrumentation system call and move the header file to uapi. The
second parameter will continue to do nothing but older kernel
versions only accepted valid real-time signal numbers. The details
will be documented in the man-page for the system call.
- Corrections and improvements for the s390 specific documentation
- Add a line to /proc/sysinfo to display the CPU model dependent
license-internal-code identifier
- A header file include fix for eadm.
- An error message fix in the kprobes code.
- The removal of an outdated ARCH_xxx select statement"
