====================
This set brings in the rest of map offload code held up by urgent
fixes and improvements to the BPF arrays.
The first 3 patches take care of array map offload, similarly to
hash maps the attribute validation is split out to a separate map
op, and used for both offloaded and non-offloaded case (allocation
only happens if map is on the host). Offload support comes down
to allowing this map type through the offload check in the core.
NFP driver also rejects the delete operation in case of array maps.
Subsequent patches add reporting of target device in a very similar
way target device of programs is reported (ifindex+netns dev/ino).
Netdevsim is extended with a trivial map implementation allowing us
to test the offload in test_offload.py.
Last patch adds a small busy wait to NFP map IO, this improves the
response times which is especially useful for map dumps.

syzbot reported yet another crash [1] that is caused by
insufficient validation of DODGY packets.
Two bugs are happening here to trigger the crash.
1) Flow dissection leaves with incorrect thoff field.
2) skb_probe_transport_header() sets transport header to this invalid
thoff, even if pointing after skb valid data.
3) qdisc_pkt_len_init() reads out-of-bound data because it
trusts tcp_hdrlen(skb)
Possible fixes :
- Full flow dissector validation before injecting bad DODGY packets in
the stack.
This approach was attempted here : https://patchwork.ozlabs.org/patch/
861874/
- Have more robust functions in the core.
This might be needed anyway for stable versions.
This patch fixes the flow dissection issue.

Since enums do not get converted by the TRACE_EVENT macro into their values,
the event format displaces the enum name and not the value. This breaks
tools like perf and trace-cmd that need to interpret the raw binary data. To
solve this, an enum map was created to convert these enums into their actual
numbers on boot up. This is done by TRACE_EVENTS() adding a
TRACE_DEFINE_ENUM() macro.
Some enums were not being converted. This was caused by an optization that
had a bug in it.
All calls get checked against this enum map to see if it should be converted
or not, and it compares the call's system to the system that the enum map
was created under. If they match, then they call is processed.
To cut down on the number of iterations needed to find the maps with a
matching system, since calls and maps are grouped by system, when a match is
made, the index into the map array is saved, so that the next call, if it
belongs to the same system as the previous call, could start right at that
array index and not have to scan all the previous arrays.
The problem was, the saved index was used as the variable to know if this is
a call in a new system or not. If the index was zero, it was assumed that
the call is in a new system and would keep incrementing the saved index
until it found a matching system. The issue arises when the first matching
system was at index zero. The next map, if it belonged to the same system,
would then think it was the first match and increment the index to one. If
the next call belong to the same system, it would begin its search of the
maps off by one, and miss the first enum that should be converted. This left
a single enum not converted properly.
Also add a comment to describe exactly what that index was for. It took me a
bit too long to figure out what I was thinking when debugging this issue.

check is redundant. Since the if branch is only hit if the context is one of
NMI, IRQ, or SOFTIRQ, if it's not NMI or IRQ there's no reason to check if
it is SOFTIRQ. The current code returns the same result even if its not a

other errors):

The Lantiq platform already worked around the same issue in commit
9050d50e22 ("MIPS: lantiq: Set physical_memsize") by declaring
physical_memsize with the initial value of 0 (on the assumption that the
actual memory size will be hard-coded in the loaded VPE firmware), and
the Malta platform already provided physical_memsize.
Since all other platforms will fail to link with the VPE loader enabled,
only allow Lantiq and Malta platforms to enable it, by way of a
SYS_SUPPORTS_VPE_LOADER which is selected by those two platforms and
which MIPS_VPE_LOADER depends on. SYS_SUPPORTS_MULTITHREADING is now a
dependency of SYS_SUPPORTS_VPE_LOADER so that Kconfig emits a warning if

Commit 8224b2734a ("NFS: Add static NFS I/O tracepoints") had a
hack to work around some odd behavior observed with
__print_symbolic. I couldn't ever get it to display NFS_FILE_SYNC
when using TRACE_DEFINE_ENUM macros to set up the enum values.
I tracked down the actual bug that forced me to add the workaround.
That issue will be addressed soon, so replace the hack with a proper
implementation.
