Treat R_X86_64_PLT32 relocs as R_X86_64_PC32.

If we load a binary that is designed to be a library, it produces
relocatable code via assembler directives in the assembly itself
(rather than compiler options).  This emits R_X86_64_PLT32 relocations,
which are not handled by the kernel linker.

MFC r338038: Extending the delay cycles to give the codec more time to pump ADC data across the AC-link.

2018-08-26T13:06:57+00:00

Without this patch, some CS4614 cards will need users to reload the driver manually or
the hardware won't be initialised properly. Something like:

	# kldload snd_csa
	# kldunload snd_csa
	# kldload snd_csa

Tested with:	Terratec SiXPack 5.1+

Disallow TUN and TAP character device IOCTLs to modify the network device
type to any value. This can cause page faults and panics due to accessing
uninitialized fields in the "struct ifnet" which are specific to the network
device type.

MFC r318860:

Declare the "snd_fxdiv_table" once. This shaves around 24Kbytes of
binary data from sound.ko and the kernel.

MFC r318820:

2017-05-27T08:30:32+00:00

Increase the allowed maximum number of audio channels from 31 to 127
in the PCM feeder mixer. Without this change a value of 32 channels is
treated like zero, due to using a mask of 0x1f, causing a kernel
assert when trying to playback bitperfect 32-channel audio. Also
update the AWK script which is generating the division tables to
handle more than 18 channels. This commit complements r282650.
