6b3c5e8bb2 x86 link: Specify ALIGN_WITH_INPUT for XIP data sections
Binutils ld has an annoying misfeature (apparently a regression from a
few years ago) that alignment directives (and alignment specifiers on
symbols) apply only to the runtime addresses and not, apparently, to
the load address region specified with the "AT>" syntax.  The net
result is that by default the LMA output ends up too small for the
addresses generated in RAM.  See here for some details:

    https://sourceware.org/ml/binutils/2013-06/msg00246.html
    https://sourceware.org/ml/binutils/2014-01/msg00350.html

The required workaround/fix is that AFAICT any section which can have
inherit a separate VMA vs. LMA from a previous section must specify an
"ALIGN_WITH_INPUT" attribute.  Otherwise the sections will get out of
sync and the XIP data will be wrong at runtime.

No, I don't know why this isn't the default behavior.

A further complexity is that this feature only works as advertised
when the section is declared with the "AT> region" syntax after the
block and not "AT(address)" in the header.  If you use the header
syntax (with or without ALIGN_WITH_INPUT), ld appears to DOUBLE-apply
padding and the LMA ends up to big.  This is almost certainly a
binutils bug, but it's trivial to work around (and the working syntax
is actually cleaner) so we adjust the usage here.

Note finally that this patch includes an effective reversion of commit
d82e9dd9 ("x86: HACK force alignment for _k_task_list section"), which
was an earlier workaround for what seems to be the same issue.

27fc467e74 net: buf: Allow NULL head pointer when inserting to frag list
To avoid extra logic in code that creates net_buf fragment lists, make
it possible to pass a NULL pointer as the head net_buf when there are
no previous buffers. Before this change the code would look like this:

	if (head) {
		net_buf_frag_add(head, buf);
	} else {
		head = net_buf_ref(buf);
	}

After the patch the code can simply do:

	head = net_buf_frag_add(head, buf);

This will then do the right thing regardless if head is NULL or
non-NULL.
