In particular:
1) remove output of inv for scalars
2) remove _value suffixes for umin/umax/s32_min/etc (except map_value)
3) remove output of id=0
4) remove output of ref_obj_id=0

bpf, arm64: bpf trampoline for arm64
47ef389 
Add bpf trampoline support for arm64. Most of the logic is the same as
x86.

fentry before bpf trampoline hooked:
 mov x9, x30
 nop

fentry after bpf trampoline hooked:
 mov x9, x30
 bl  <bpf_trampoline>

Tested on qemu, result:
 #55 fentry_fexit:OK
 #56 fentry_test:OK
 #58 fexit_sleep:OK
 #59 fexit_stress:OK
 #60 fexit_test:OK
 #67 get_func_args_test:OK

net: moxa: get rid of asymmetry in DMA mapping/unmapping
0ee7828 
Since priv->rx_mapping[i] is maped in moxart_mac_open(), we
should unmap it from moxart_mac_stop(). Fixes 2 warnings.

1. During error unwinding in moxart_mac_probe(): "goto init_fail;",
then moxart_mac_free_memory() calls dma_unmap_single() with
priv->rx_mapping[i] pointers zeroed.

netfilter: nf_tables: deactivate catchall elements in next generation
90e5b34 
When flushing, individual set elements are disabled in the next
generation via the ->flush callback.

Catchall elements are not disabled.  This is incorrect and may lead to
double-deactivations of catchall elements which then results in memory
leaks:

WARNING: CPU: 1 PID: 3300 at include/net/netfilter/nf_tables.h:1172 nft_map_deactivate+0x549/0x730
CPU: 1 PID: 3300 Comm: nft Not tainted 6.5.0-rc5+ #60
RIP: 0010:nft_map_deactivate+0x549/0x730
 [..]
 ? nft_map_deactivate+0x549/0x730
 nf_tables_delset+0xb66/0xeb0

(the warn is due to nft_use_dec() detecting underflow).

Fixes: aaa3104 ("netfilter: nftables: add catch-all set element support")

selftests/bpf: don't truncate #test/subtest field
f74af5b 
We currently expect up to a three-digit number of tests and subtests, so:

  #999/999: some_test/some_subtest: ...

Is the largest test/subtest we can see. If we happen to cross into
1000s, current logic will just truncate everything after 7th character.
This patch fixes this truncate and allows to go way higher (up to 31
characters in total). We still nicely align test numbers:

  #60/66   core_reloc_btfgen/type_based___incompat:OK
  #60/67   core_reloc_btfgen/type_based___fn_wrong_args:OK
  #60/68   core_reloc_btfgen/type_id:OK
  #60/69   core_reloc_btfgen/type_id___missing_targets:OK
  #60/70   core_reloc_btfgen/enumval:OK
