Michael, as the author of the this commit, could you please look into
this issue?
We could revert your patch, which appears to work for some users,
but that would again break setups with PAGE_SIZE == 64K.
(I assume that Jonáš and Kolbjørn are not building with PAGE_SIZE == 64K.)
This is from a PPC32 machine, so it doesn't even have that option.
It only supports 4K pages.

kernel BUG at drivers/ata/pata_macio.c:544!
https://github.com/torvalds/linux/blob/v6.11-rc3/drivers/ata/pata_macio.c#L544
It seems that the
while (sg_len) loop does not play nice with the new .max_segment_size.
Oops: Exception in kernel mode, sig: 5 [#1]
