Bug 1945576: Intel I225-IT device probe failure

5bab619... by Sasha Neftin on 2021-07-10

igc: Remove phy->type checking

BugLink: https://bugs.launchpad.net/bugs/1945576

i225 devices have only one phy->type: copper. There is no point checking
phy->type during the igc_has_link method from the watchdog that
invoked every 2 seconds.
This patch comes to clean up these pointless checkings.

igc: Remove _I_PHY_ID checking

BugLink: https://bugs.launchpad.net/bugs/1945576

i225 devices have only one PHY vendor. There is no point checking
_I_PHY_ID during the link establishment and auto-negotiation process.
This patch comes to clean up these pointless checkings.

Discard .note.gnu.property sections in generic NOTES

BugLink: https://bugs.launchpad.net/bugs/1929889

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:

PHDRS {
 text PT_LOAD FLAGS(5);
 data PT_LOAD FLAGS(6);
 percpu PT_LOAD FLAGS(6);
 init PT_LOAD FLAGS(7);
 note PT_NOTE FLAGS(0);
}
SECTIONS
{
...
 .notes : AT(ADDR(.notes) - 0xffffffff80000000) { __start_notes = .; KEEP(*(.not
e.*)) __stop_notes = .; } :text :note
...
}

The NOTE segment generated by kernel linker script is aligned to 4 bytes.
But .note.gnu.property section must be aligned to 8 bytes on x86-64 and
we get

[hjl@gnu-skx-1 linux]$ readelf -n vmlinux

Displaying notes found in: .notes
  Owner Data size Description

readelf: Warning: note with invalid namesz and/or descsz found at offset 0x50
readelf: Warning: type: 0xffffffff, namesize: 0x006e6558, descsize:

[hjl@gnu-skx-1 linux]$

Since note.gnu.property section in kernel image is never used, this patch
discards .note.gnu.property sections in kernel linker script by adding

/DISCARD/ : {
  *(.note.gnu.property)
}

before kernel NOTE segment in generic NOTES.
