\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add SPDX license identifiers to all files which: - Have no license information of any form - Have EXPORT_.*_SYMBOL_GPL inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only.

*	hlist: drop the node parameter from iterators	Sasha Levin	2013-02-27	1	-2/+2

I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S \| hlist_for_each_entry_continue(a, - b, c) S \| hlist_for_each_entry_from(a, - b, c) S \| hlist_for_each_entry_rcu(a, - b, c, d) S \| hlist_for_each_entry_rcu_bh(a, - b, c, d) S \| hlist_for_each_entry_continue_rcu_bh(a, - b, c) S \| for_each_busy_worker(a, c, - b, d) S \| ax25_uid_for_each(a, - b, c) S \| ax25_for_each(a, - b, c) S \| inet_bind_bucket_for_each(a, - b, c) S \| sctp_for_each_hentry(a, - b, c) S \| sk_for_each(a, - b, c) S \| sk_for_each_rcu(a, - b, c) S \| sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S \| sk_for_each_safe(a, - b, c, d) S \| sk_for_each_bound(a, - b, c) S \| hlist_for_each_entry_safe(a, - b, c, d, e) S \| hlist_for_each_entry_continue_rcu(a, - b, c) S \| nr_neigh_for_each(a, - b, c) S \| nr_neigh_for_each_safe(a, - b, c, d) S \| nr_node_for_each(a, - b, c) S \| nr_node_for_each_safe(a, - b, c, d) S \| - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S \| - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S \| for_each_host(a, - b, c) S \| for_each_host_safe(a, - b, c, d) S \| for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

*	kernel: Map most files to use export.h instead of module.h	Paul Gortmaker	2011-10-31	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The changed files were only including linux/module.h for the EXPORT_SYMBOL infrastructure, and nothing else. Revector them onto the isolated export header for faster compile times. Nothing to see here but a whole lot of instances of: -#include <linux/module.h> +#include <linux/export.h> This commit is only changing the kernel dir; next targets will probably be mm, fs, the arch dirs, etc. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Today's linux-next build (x86_64 allmodconfig) failed like this: kernel/user-return-notifier.c: In function 'fire_user_return_notifiers': kernel/user-return-notifier.c:45: error: expected expression before ')' token Introduced by commit 7c68af6e32c73992bad24107311f3433c89016e2 ("core, x86: Add user return notifiers") from the tip and kvm trees but revealed by commit e0fdb0e050eae331046385643618f12452aa7e73 ("percpu: add __percpu for sparse") from the percpu tree. Before that percpu tree commit, "put_cpu_var()" would compile without error (even though it really needs a parameter).

*	core, x86: Add user return notifiers	Avi Kivity	2009-10-01	1	-0/+46
	Add a general per-cpu notifier that is called whenever the kernel is about to return to userspace. The notifier uses a thread_info flag and existing checks, so there is no impact on user return or context switch fast paths. This will be used initially to speed up KVM task switching by lazily updating MSRs.
