'disklabel -r -w' writes a disklabel at a wrong sector in
NATIVELABEL_ONLY && !LABELUSESMBR && LABELSECTOR != 0 case
if the target disk doesn't have a valid disklabel, due to
incorrect LABEL_OFFSET value.
Found and investigated on NetBSD/hp300 bootable CD tests.
Maybe this affects ports that use distrib/utils/x_disklabel
but have no MBR support, i.e. only NetBSD/hp300 10.0 and
NetBSD/ews4800mips 9.0 and later.
Should be pulled up to netbsd-10 and netbsd-9.
Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.
GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH
Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.
GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)
use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.
we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."
Make options to chose alternate label position for systems using MBR
more intuitive. -m now selects mode with MBR, -n selects mode without,
independent of the machine defaults.
- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)
After that chanage, "MAXPARTITIONS" constant is not for the target port.
If host's MAXPARTITIONS is larger than a value of the target label and
target endianness is different from the build host, bswaplabel() could
overwrite data beyond the disklabel and primary boot stored after
LABELSECTOR in images might be corrupted.
This fixes boot failure of sun2 liveimage built by
"build.sh -U -m sun2 release live-image"
on TME.
Should be pulled up to netbsd-7.

This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.
