This IR uses NEC protocol, with address=0x14. This keymap is similar
to the existing Terratec Cinergy XS, except that:
- it contains the full address/command code;
- the Music button were mapped as KEY_RADIO;
- some keycodes from the previous entry were wrong, IMHO.

Commit 5601a00d67 (nfs: run state manager
in privileged mode) introduces a regression in the NFSv4 code when
compiled with CONFIG_NFS_V4_1. The calls to nfs4_end_drain_session()
from the main loop in nfs4_state_manager() Oops due to the lack of an
NFSv4.1 session when running NFSv4.0.
The fix is to move those two calls back into nfs41_init_clientid() and
nfs4_reset_session().
The calls to nfs4_end_drain_session() that remain inside
nfs4_state_manager() are safe, since the NFSv4.0 code will never set the
NFS4CLNT_SESSION_DRAINING bit.

This allows ipmi_si_intf.c to claim IPMI devices described in the ACPI

The instruction attribute table generator fails when run by mawk
or original-awk:
$ mawk -f arch/x86/tools/gen-insn-attr-x86.awk \
arch/x86/lib/x86-opcode-map.txt > /dev/null
Semantic error at 240: Second IMM error
$ echo $?
1
Line 240 contains "c8: ENTER Iw,Ib", which indicates that this
instruction has two immediate operands, the second of which is
one byte. The script loops through the immediate operands using
a for loop.
Unfortunately, there is no guarantee in awk that a for (variable
in array) loop will return the indices in increasing order.
Internally, both original-awk and mawk iterate over a hash table
for this purpose, and both implementations happen to produce the
index 2 before 1. The supposed second immediate operand is more
than one byte wide, producing the error.
So loop over the indices in increasing order instead. As a
side-effect, with mawk this means the silly two-entry hash table
never has to be built.
