2013-04-29atm: he: use mdelay instead of large udelay constantsArnd Bergmann
ARM cannot handle udelay for more than 2 miliseconds, and it is rather bad style to block the cpu for 16ms anyway, so let's use msleep instead. Signed-off-by: Arnd Bergmann <> Cc: Chas Williams <> Cc: Cc: Signed-off-by: David S. Miller <>
2013-02-27hlist: drop the node parameter from iteratorsSasha Levin
I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? 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 ) ...+> [ drop bogus change from net/ipv4/raw.c] [ drop bogus hunk from net/ipv6/raw.c] [ checkpatch fixes] [ fix warnings] [ redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <> Acked-by: Paul E.

2013-02-08atm/iphase: rename fregt_t -> ffreg_tHeiko Carstens
We have conflicting type qualifiers for "freg_t" in s390's ptrace.h and the iphase atm device driver, which causes the compile error below. Unfortunately the s390 typedef can't be renamed, since it's a user visible api, nor can I change the include order in s390 code to avoid the conflict. So simply rename the iphase typedef to a new name.

2012-05-24solos-pci: Fix DMA supportDavid Woodhouse
DMA support has finally made its way to the top of the TODO list, having realised that a Geode using MMIO can't keep up with two ADSL2+ lines each running at 21Mb/s. This patch fixes a couple of bugs in the DMA support in the driver, so once the corresponding FPGA update is complete and tested everything should work properly. We weren't storing the currently-transmitting skb, so we were never unmapping it and never freeing/popping it when the TX was done. And the addition of pci_set_master() is fairly self-explanatory.

2012-05-06skb: Add inline helper for getting the skb end offset from headAlexander Duyck

2011-05-18drivercore: revert addition of of_match to struct deviceGrant Likely
Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <>
