af1032a21b lint: add test for assertion failure in initialization 
The 'cnt = level->bl_type->t_tspec == STRUCT ? 2 : 1;' in
initialization_push_struct_or_union is obviously wrong since not every
struct has exactly 1 remaining member after the first member that has an
initializer with designation.

This bug started its life in init.c 1.12 from 2002-10-21, a little over
18 years ago.

94f17677cf lint: only define GCC builtins if -g is given 
This removes 7 wrong warnings when running lint in -t mode.

Surprisingly, this added a warning that had not been there before in
msg_189.c.  This is because check_variable_usage skips the checks when
an error occurred before.  All diagnostics that happened were warnings,
but the -w option treats them as errors, see vwarning.

034864b5d3 lint: remove wrong warning about wrong initializer type 
The following code is valid:

	int valid = {{{ 3 }}};

C90 3.5.7 and C99 6.7.8 both say that the "initializer for a scalar
shall be a single expression, optionally enclosed in braces".  They
don't put any upper bound on the amount of braces, not even in the
"Translation limits" section.

issue in the USB stack -- signaling transfer complete on multiple PEs can

It did not make sense to have this code between the code for the

types, move it to the top.

2aee461d79 Only target the boot cpu for real with SPI interrupts. I tried to do 
this back in 2014, but somehow I missed a spot.

This is a quick-and-dirty fix for the USB stack which expects transfer
completions to be in-order.  If interrupts happen across the CPUs then
this isn't guaranteed (yet).

7ec5b82b08 In getvfsstat(2), clarify that the size argument is in bytes. 
That the size argument is in bytes (not the count of structures) and
the return value is the count of structures (not bytes) is
counterintuitive.
