linux/list.h: Add list_safe_reset_next.

Provide list_for_each_entry_safe_reverse and reorder for consistency

list_for_each_entry_from_reverse

list_bulk_move_tail

Omit outdated comment.

provide list_for_each_entry_from (XXX needs review)


Author: Maya Rashish <maya@NetBSD.org>

provide list_is_first


Author: Maya Rashish <maya@NetBSD.org>

list_is_last

__list_del_entry, and poison list_del.

Move struct list_head to <linux/types.h>.

Add LIST_HEAD to <linux/nbsd-namespace.h> too.

branches: 1.18.6;
Define list_splice_init.

Make sure to call pslist_entry_init.

Give hlist iteration half a chance of working, oops.

Implement list_splice_tail_init.

Add list_replace_init.

Fix hlist_for_each_entry_safe: temp is hlist_node, not element.

Fix order of arguments of hlist_add_head_rcu.

Fix hlist_for_each_entry_rcu like hlist_for_each_entry.

Define list_entry_first_or_null.

Fix hlist iteration again with more fields and null checks.

Fix hlist_for_each_entry to use the specified field.

Rewrite linux hlist with our pslist.

Upstream uses RCU for this now, so we need it.

Rewrite hashtable.h locally so it might work here.

branches: 1.5.18; 1.5.20;
Add some Linux list routines.

branches: 1.4.2; 1.4.4;
First whack at radeon driver.

No hardware to test yet, but it builds.

Make it build and boot on my test machines.

Screen blanks on boot on the Ivy Bridge system with

DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun

But after that everything is OK. Appears to be an upstream problem.
To investigate...

I think there's a cache flushing issue somewhere -- there are little
display artefacts on my T60.

Add some notes on using these shims to port Linux kernel code.

branches: 1.1.2; 1.1.4; 1.1.6;
Pull across some linux header files from riastradh-drm2, but put them
in a shared location.

Riastradh: nick, OK.
