Convert the uses mac addresses to ETH_ALEN so
it's easier to find and verify where mac addresses
need to be __aligned(2)
Change from initial submission:
- Remove include/acpi/actbl2.h conversion
It's a file copied from outside ACPI sources

It's convenient to have ethernet mac addresses use
ETH_ALEN to be able to grep for them a bit easier and
also to ensure that the addresses are __aligned(2).
Add #include <linux/if_ether.h> as necessary.

* [PATCH V2 2/3] include: Convert ethernet mac address declarations to use ETH_ALEN
@ 2013-08-01 20:14 ` Joe Perches

It's convenient to have ethernet mac addresses use
ETH_ALEN to be able to grep for them a bit easier and
also to ensure that the addresses are __aligned(2).
Add #include <linux/if_ether.h> as necessary.

Use the normal #define to help grep find mac addresses
and ensure that addresses are aligned.
Move one address in pasemi_mac.h for alignment.

Just promote 'type' to u32 instead, saves you from moving the #defines
down, etc, etc.

There's a more fundamental question which has to be asked: what is the
point of moving that in the first place?

type is already u8, why change it?
That would also change struct size.

Some is_<foo>_ether_addr tests assume __aligned(2)
by a casting char * to u16/be16 * and dereferencing.

This seems rather obscure - I mean, it's not obvious to driver authors
that should be the case. Would it not be better to make this a little
more obvious somehow? Maybe __aligned(2) against mac_addr? Or
maybe have a debugging check for it?

That'd be for David Miller (cc'd).
I believe he's argued in the past that any alignment check
for mac addresses was unnecessary.
For all I know it really might not matter because pasemi
can successfully dereference a ushort against an odd char
pointer.
I just noticed it and thought it'd be better moved.

As can ARM too for years now - either in hardware or via fixup for
kernel code.

But probably not a good idea if it's done in a fast path.

This particular driver is for the PA Semi chips, and I very much doubt
that compatible hardware will ever show up anywhere else; they're
fairly dependent on the I/O architecture of the chip and Apple has not
brought those aspects forward in their ARM chips, as far as I know.
So, you might as well leave the code alone for now. It's not used on
fast path, and the system definitely handles unaligned accesses for
this -- it has for years already.

Convert the uses mac addresses to ETH_ALEN so
it's easier to find and verify where mac addresses
need to be __aligned(2)
Change in V2:
- Remove include/acpi/actbl2.h conversion
It's a file copied from outside ACPI sources
Changes in V3:
- Don't move the pasemi_mac.h mac address to be aligned(2)
Just note that it's unaligned.

It's convenient to have ethernet mac addresses use
ETH_ALEN to be able to grep for them a bit easier and
also to ensure that the addresses are __aligned(2).
Add #include <linux/if_ether.h> as necessary.

* [PATCH V3 3/3] ethernet: Convert mac address uses of 6 to ETH_ALEN
2013-08-01 23:17 ` Joe Perches
@ 2013-08-01 23:17 ` Joe Perches

From: Joe Perches @ 2013-08-01 23:17 UTC (permalink / raw)
To: linux-arm-kernel
Use the normal #define to help grep find mac addresses
and ensure that addresses are aligned.
pasemi.h has an unaligned access to mac_addr, unchanged
for now.
