2010-12-10usb: musb: trivial search and replace patchFelipe Balbi
change all ocurrences of musb_hdrc to musb-hdrc. We will call glue layer drivers musb-<glue layer>, so in order to keep things somewhat standard, let's change the underscore into a dash. Signed-off-by: Felipe Balbi <balbi@ti.com>
2010-12-10usb: musb: add Kconfig options for each glue layerFelipe Balbi
This will make things simpler when choosing which glue layer to compile. It avoids a lot of magic around the "default" Kconfig option and lets the user choose what exactly s/he wants to compile. Signed-off-by: Felipe Balbi <balbi@ti.com>

when we start splitting HW glue layer, it's gonna make it easier to re-use that structure. Signed-off-by: Felipe Balbi <balbi@ti.com>

2010-12-09bnx2x: LSO code was broken on BE platformsVladislav Zolotarov
Make the LSO code work on BE platforms: parsing_data field of a parsing BD (PBD) for 57712 was improperly composed which made FW read wrong values for TCP header's length and offset and, as a result, the corresponding PCI device was performing bad DMA reads triggering EEH.

2010-12-09filter: use size of fetched data in __load_pointer()Eric Dumazet
__load_pointer() checks data we fetch from skb is included in head portion, but assumes we fetch one byte, instead of up to four. This wont crash because we have extra bytes (struct skb_shared_info) after head, but this can read uninitialized bytes. Fix this using size of the data (1, 2, 4 bytes) in the test.

2010-12-09hso: IP checksuming doesn't work on GE0301 option cardsThomas Bogendoerfer
There is definitly a problem, that some option cards send up broken IP pakets leading to corrupted IP packets. These corruptions aren't detected, because the driver claims that the packets are already checksummed. This change removes the CHECKSUM_UNNECESSARY option and let IP detect broken data.

2010-12-09net: Convert netpoll blocking api in bonding driver to be a counterNeil Horman
A while back I made some changes to enable netpoll in the bonding driver. Among them was a per-cpu flag that indicated we were in a path that held locks which could cause the netpoll path to block in during tx, and as such the tx path should queue the frame for later use. This appears to have given rise to a regression. If one of those paths on which we hold the per-cpu flag yields the cpu, its possible for us to come back on a different cpu, leading to us clearing a different flag than we set. This results in odd netpoll drops, and BUG backtraces appearing in the log, as we check to make sure that we only clear set bits, and only set clear bits. I had though briefly about changing the offending paths so that they wouldn't sleep, but looking at my origional work more closely, it doesn't appear that a per-cpu flag is warranted. We alrady gate the checking of this flag on IFF_IN_NETPOLL, so we don't hit this in the normal tx case anyway. And practically speaking, the normal use case for netpoll is to only have one client anyway, so we're not going to erroneously queue netpoll frames when its actually safe to do so. As such, lets just convert that per-cpu flag to an atomic counter. It fixes the rescheduling bugs, is equivalent from a performance perspective and actually eliminates some code in the process.

2010-12-09The new jhash implementationJozsef Kadlecsik
The current jhash.h implements the lookup2() hash function by Bob Jenkins. However, lookup2() is outdated as Bob wrote a new hash function called lookup3(). The patch replaces the lookup2() implementation of the 'jhash*' functions with that of lookup3(). You can read a longer comparison of the two and other hash functions at http://burtleburtle.net/bob/hash/doobs.html.

2010-12-09net: optimize INET input path furtherEric Dumazet
Followup of commit b178bb3dfc30 (net: reorder struct sock fields) Optimize INET input path a bit further, by : 1) moving sk_refcnt close to sk_lock. This reduces number of dirtied cache lines by one on 64bit arches (and 64 bytes cache line size). 2) moving inet_daddr & inet_rcv_saddr at the beginning of sk (same cache line than hash / family / bound_dev_if / nulls_node) This reduces number of accessed cache lines in lookups by one, and dont increase size of inet and timewait socks. inet and tw sockets now share same place-holder for these fields. Before patch : offsetof(struct sock, sk_refcnt) = 0x10 offsetof(struct sock, sk_lock) = 0x40 offsetof(struct sock, sk_receive_queue) = 0x60 offsetof(struct inet_sock, inet_daddr) = 0x270 offsetof(struct inet_sock, inet_rcv_saddr) = 0x274 After patch : offsetof(struct sock, sk_refcnt) = 0x44 offsetof(struct sock, sk_lock) = 0x48 offsetof(struct sock, sk_receive_queue) = 0x68 offsetof(struct inet_sock, inet_daddr) = 0x0 offsetof(struct inet_sock, inet_rcv_saddr) = 0x4 compute_score() (udp or tcp) now use a single cache line per ignored item, instead of two.

2010-12-09OMAP2+: PM/serial: fix console semaphore acquire during suspendKevin Hilman
commit 0d8e2d0dad98a693bad88aea6876ac8b94ad95c6 (OMAP2+: PM/serial: hold console semaphore while OMAP UARTs are disabled) added use of the console semaphore to protect UARTs from being accessed after disabled during idle, but this causes problems in suspend. During suspend, the console semaphore is acquired by the console suspend method (console_suspend()) so the try_acquire_console_sem() will always fail and suspend will be aborted. To fix, introduce a check so the console semaphore is only attempted during idle, and not during suspend. Also use the same check so that the console semaphore is not prematurely released during resume. Thanks to Paul Walmsley for suggesting adding the same check during resume.
