This change cleans up some instances where unsigned int and u32 were being used interchangeably, and cleans up hdr_len which was being set to 0 twice.

This patch adds calls to pci_save_state() immediately after calls to pci_restore_state(). Due to a change in the behavior of pci_restore_state() it is necessary to call pci_save_state() to keep the state_saved flag. This patch is based on a similar patch for ixgbe.

Add __percpu sparse annotations to net. These annotations are to make sparse consider percpu variables to be in a different address space and warn if accessed without going through percpu accessors. This patch doesn't affect normal builds. The macro and type tricks around snmp stats make things a bit interesting. DEFINE/DECLARE_SNMP_STAT() macros mark the target field as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly. All snmp_mib_*() users which used to cast the argument to (void **) are updated to cast it to (void __percpu **). Signed-off-by: NTejun Heo <tj@kernel.org> Acked-by: NDavid S.

Eric's version fixed it for pfkey. This one is for xfrm user. I thought about amortizing those two get_acqseq()s but it seems reasonable to have two of these sequence spaces for the two different interfaces. cheers, jamal commit d5168d5addbc999c94aacda8f28a4a173756a72b Author: Jamal Hadi Salim <hadi@cyberus.ca> Date: Tue Feb 16 06:51:22 2010 -0500 xfrm: avoid spinlock in get_acqseq() used by xfrm user This is in the same spirit as commit 28aecb9d by Eric Dumazet.

This strange special rule to fall back to controller 1 cannot be derived from the CAPI specs and looks a lot like it was once dedicated to some out-of-tree driver, probably AVM's broken fcdsl2 (FRITZ!Card DSL v2.0). I found no in-tree user that needs this check, and I'm now taking care of the fcdsl2. So drop these bits from our stack. Signed-off-by: NJan Kiszka <jan.kiszka@web.de> Signed-off-by: NDavid S.

Introduce outlock as a spin lock that protects capiminor's outqueue, outbytes and outskb (formerly known as ttyskb). outlock can be acquired from soft-IRQ context via capinc_write, so make it bh-safe. This finally removes the last reason for keeping the workaround lock around (which was incomplete and partly broken anyway). And as we no longer call handle_recv_skb in atomic context, gen_data_b3_resp_for can use non-atomic allocation now. Signed-off-by: NJan Kiszka <jan.kiszka@web.de> Signed-off-by: NDavid S.
