The third-party 802.11 stack and NFS protocol code are known to
include multiple potential vulnerabilities and are explicitly
forbidden from being included in Secure Boot signed builds. This is
currently handled at the per-directory level by defining a list of
source directories (SRCDIRS_INSEC) that are to be excluded from Secure
Boot builds.
Annotate all files in these directories with FILE_SECBOOT() to convey
this information to the new per-file Secure Boot permissibility check,
and remove the old separation between SRCDIRS and SRCDIRS_INSEC.

Done with the help of this Perl script:
$MARKER = 'PCI_ROM'; # a regex
$AB = 1; # At Begin
@HEAD = ();
@ITEMS = ();
@TAIL = ();
foreach $fn (@ARGV) {
open(IN, $fn) or die "Can't open file '$fn': $!\n";
while (<IN>) {
if (/$MARKER/) {
push @ITEMS, $_;
$AB = 0; # not anymore at begin
}
else {
if ($AB) {
push @HEAD, $_;
}
else {
push @TAIL, $_;
}
}
}
} continue {
close IN;
open(OUT, ">$fn") or die "Can't open file '$fn' for output: $!\n";
print OUT @HEAD;
print OUT sort @ITEMS;
print OUT @TAIL;
close OUT;
# For a next file
$AB = 1;
@HEAD = ();
@ITEMS = ();
@TAIL = ();
}
Executed that script while src/drivers/ as current working directory,
provided '$(grep -rl PCI_ROM)' as argument.

The GCC11 compiler pointed out something that apparently no previous
compiler noticed: in ath5k_eeprom_pread_turbo_modes, local variable
val is used uninitialized. From what I can see, the code is just
missing an initial AR5K_EEPROM_READ. Add it right before the switch
statement.

The malloc_dma() function allocates memory with specified physical
alignment, and is typically (though not exclusively) used to allocate
memory for DMA.
Rename to malloc_phys() to more closely match the functionality, and
to create name space for functions that specifically allocate and map
DMA-capable buffers.

Several files define the ARRAY_SIZE() macro as used in Linux. Provide
a common definition for this in include/compiler.h.

Allow the active timer (providing udelay() and currticks()) to be
selected at runtime based on probing during the INIT_EARLY stage of
initialisation.
TICKS_PER_SEC is now a fixed compile-time constant for all builds, and
is independent of the underlying clock tick rate. We choose the value
1024 to allow multiplications and divisions on seconds to be converted
to bit shifts.
TICKS_PER_MS is defined as 1, allowing multiplications and divisions
on milliseconds to be omitted entirely. The 2% inaccuracy in this
definition is negligible when using the standard BIOS timer (running
at around 18.2Hz).
TIMER_RDTSC now checks for a constant TSC before claiming to be a
usable timer. (This timer can be tested in KVM via the command-line
option "-cpu host,+invtsc".)

ath_rx_init() demonstrates some serious confusion over how to use
pointers, resulting in (uint32_t*)NULL being used as a temporary
variable. This does not end well.
The broken code in question is performing manual alignment of I/O
buffers, which can now be achieved more simply using alloc_iob_raw().
Fix by removing ath_rxbuf_alloc() entirely.

This changed in Linux kernel the same way in commit 7067e701
("ath9k_hw: remove confusing logic inversion in an ANI variable") by
Felix Fietkau.
Additionally this fixes "error: logical not is only applied to the
left hand side of comparison" with GCC 5.1.0.
