This function is obfuscating how IO works on this chip. Remove it and push its logic into brcmf_sdiod_reg_{read,write}(). Handling of -ENOMEDIUM is altered, but as that's pretty much broken anyway we can ignore that.

David Miller says: ==================== net: Significantly shrink the size of routes. Through a combination of several things, our route structures are larger than they need to be. Mostly this stems from having members in dst_entry which are only used by one class of routes. So the majority of the work in this series is about "un-commoning" these members and pushing them into the type specific structures. Unfortunately, IPSEC needed the most surgery. The majority of the changes here had to do with bundle creation and management. The other issue is the refcount alignment in dst_entry. Once we get rid of the not-so-common members, it really opens the door to removing that alignment entirely. I think the new layout looks really nice, so I'll reproduce it here: struct net_device *dev; struct dst_ops *ops; unsigned long _metrics; unsigned long expires; struct xfrm_state *xfrm; int (*input)(struct sk_buff *); int (*output)(struct net *net, struct sock *sk, struct sk_buff *skb); unsigned short flags; short obsolete; unsigned short header_len; unsigned short trailer_len; atomic_t __refcnt; int __use; unsigned long lastuse; struct lwtunnel_state *lwtstate; struct rcu_head rcu_head; short error; short __pad; __u32 tclassid; (This is for 64-bit, on 32-bit the __refcnt comes at the very end) So, the good news: 1) struct dst_entry shrinks from 160 to 112 bytes. 2) struct rtable shrinks from 216 to 168 bytes. 3) struct rt6_info shrinks from 384 to 320 bytes. Enjoy. v2: Collapse some patches logically based upon feedback. Fix the strange patch #7. v3: xfrm_dst_path() needs inline keyword Properly align __refcnt on 32-bit. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

While building ipsec bundles, blocks of xfrm dsts are linked together using dst->next from bottom to the top. The only thing this is used for is initializing the pmtu values of the xfrm stack, and for updating the mtu values at xfrm_bundle_ok() time. The bundle pmtu entries must be processed in this order so that pmtu values lower in the stack of routes can propagate up to the higher ones. Avoid using dst->next by simply maintaining an array of dst pointers as we already do for the xfrm_state objects when building the bundle. Signed-off-by: David S.

We have padding to try and align the refcount on a separate cache line. But after several simplifications the padding has increased substantially. So now it's easy to change the layout to get rid of the padding entirely. We group the write-heavy __refcnt and __use with less often used items such as the rcu_head and the error code.

The first member of an IPSEC route bundle chain sets it's dst->path to the underlying ipv4/ipv6 route that carries the bundle. Stated another way, if one were to follow the xfrm_dst->child chain of the bundle, the final non-NULL pointer would be the path and point to either an ipv4 or an ipv6 route. This is largely used to make sure that PMTU events propagate down to the correct ipv4 or ipv6 route. When we don't have the top of an IPSEC bundle 'dst->path == dst'. Move it down into xfrm_dst and key off of dst->xfrm. Signed-off-by: David S. Miller <davem@davemloft.net> Reviewed-by: Eric Dumazet <edumazet@google.com>

The dst->from value is only used by ipv6 routes to track where a route "came from". Any time we clone or copy a core ipv6 route in the ipv6 routing tables, we have the copy/clone's ->from point to the base route. This is used to handle route expiration properly. Only ipv6 uses this mechanism, and only ipv6 code references it. So it is safe to move it into rt6_info. Signed-off-by: David S.

David Miller authored
XFRM bundle child chains look like this: xdst1 --> xdst2 --> xdst3 --> path_dst All of xdstN are xfrm_dst objects and xdst->u.dst.xfrm is non-NULL. The final child pointer in the chain, here called 'path_dst', is some other kind of route such as an ipv4 or ipv6 one. The xfrm output path pops routes, one at a time, via the child pointer, until we hit one which has a dst->xfrm pointer which is NULL. We can easily preserve the above mechanisms with child sitting only in the xfrm_dst structure. All children in the chain before we break out of the xfrm_output() loop have dst->xfrm non-NULL and are therefore xfrm_dst objects. Since we break out of the loop when we find dst->xfrm NULL, we will not try to dereference 'dst' as if it were an xfrm_dst. Signed-off-by: David S. Miller <davem@davemloft.net>

net/atm/mpoa_* files use 'struct timeval' to store event timestamps. struct timeval uses a 32-bit seconds field which will overflow in the year 2038 and beyond. Morever, the timestamps are being compared only to get seconds elapsed, so struct timeval which stores a seconds and microseconds field is an overkill. This patch replaces the use of struct timeval with time64_t to store a 64-bit seconds field.

timespec is deprecated because of the y2038 overflow, so let's convert this one to ktime_get_ts64(). The code is already safe even on 32-bit architectures, since it uses monotonic times. On 64-bit architectures, nothing changes, while on 32-bit architectures this avoids one type conversion. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.

netxen_collect_minidump() evidently just wants to get a monotonic timestamp. Using jiffies_to_timespec(jiffies, &ts) is not appropriate here, since it will overflow after 2^32 jiffies, which may be as short as 49 days of uptime. ktime_get_seconds() is the correct interface here.

Instead, just fall back on the new '%p' behavior which hashes the pointer. Otherwise, '%pK' - that was intended to mark a pointer as restricted - just ends up leaking pointers that a normal '%p' wouldn't leak. Which just make the whole thing pointless. I suspect we should actually get rid of '%pK' entirely, and make it just work as '%p' regardless, but this is the minimal obvious fix. People who actually use 'kptr_restrict' should weigh in on which behavior they want.
