Discard .note.gnu.property sections in generic NOTES
With the command-line option, -mx86-used-note=yes, the x86 assembler
in binutils 2.32 and above generates a program property note in a note
section, .note.gnu.property, to encode used x86 ISAs and features. But
kernel linker script only contains a single NOTE segment:
/DISCARD/ : { *(.note.gnu.property) }
is placed before
.rela.dyn : AT(ADDR(.rela.dyn) - (0xc000000000000000 -0x00000000))
{
__rela_dyn_start = .;
*(.rela*) <<<<<<<< Keep .rela* sections
}
Then .rela* in
/DISCARD/ : {
*(*.EMB.apuinfo)
*(.glink .iplt .plt .rela* .comment)
*(.gnu.version*)
*(.gnu.attributes)
*(.eh_frame)
}
is honored. Can someone from POWERPC comment on it?

Hmm OK. I'm not really a toolchain person.
The comment on DISCARDS says:
* Some archs want to discard exit text/data at runtime rather than
* link time due to cross-section references such as alt instructions,
* bug table, eh_frame, etc. DISCARDS must be the last of output
* section definitions so that such archs put those in earlier section
* definitions.
*/
But I guess you're changing those semantics in your series.
This seems to fix the warning for me?
