2014-01-15MIPS: fix blast_icache32 on loongson2Aaro Koskinen2-21/+29
Commit 14bd8c082016 ("MIPS: Loongson: Get rid of Loongson 2 #ifdefery all over arch/mips") failed to add Loongson2 specific blast_icache32 functions. Fix that. The patch fixes the following crash seen with 3.13-rc1: Reserved instruction in kernel code[#1]: [...] Call Trace: blast_icache32_page+0x8/0xb0 r4k_flush_cache_page+0x19c/0x200 do_wp_page.isra.97+0x47c/0xe08 handle_mm_fault+0x938/0x1118 __do_page_fault+0x140/0x540 resume_userspace_check+0x0/0x10 Code: 00200825 64834000 00200825 <bc900000> bc900020 bc900040 bc900060 bc900080 bc9000a0 Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Acked-by: John Crispin <blogic@openwrt.org> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-01-15MIPS: fix case mismatch in local_r4k_flush_icache_range()Huacai Chen3-7/+7
Currently, Loongson-2 call protected_blast_icache_range() and others call protected_loongson23_blast_icache_range(), but I think the correct behavior should be the opposite. BTW, Loongson-3's cache-ops is compatible with MIPS64, but not compatible with Loongson-2. So, rename xxx_loongson23_yyy things to xxx_loongson2_yyy. The patch fixes early boot hang with 3.13-rc1, introduced in commit 14bd8c082016 ("MIPS: Loongson: Get rid of Loongson 2 #ifdefery all over arch/mips").

There was a lot of work on the PPC side: the HV and emulation flavors can now coexist in a single kernel is probably the most interesting change from a user point of view.

Finally, there is a new interface to connect KVM with VFIO. This helps with devices that use NoSnoop PCI transactions, letting the driver in the guest execute WBINVD instructions.

Pull networking updates from David Miller: 1) The addition of nftables. No longer will we need protocol aware firewall filtering modules, it can all live in userspace. At the core of nftables is a, for lack of a better term, virtual machine that executes byte codes to inspect packet or metadata (arriving interface index, etc.) and make verdict decisions. Besides support for loading packet contents and comparing them, the interpreter supports lookups in various datastructures as fundamental operations. For example sets are supports, and therefore one could create a set of whitelist IP address entries which have ACCEPT verdicts attached to them, and use the appropriate byte codes to do such lookups. Since the interpreted code is composed in userspace, userspace can do things like optimize things before giving it to the kernel. Another major improvement is the capability of atomically updating portions of the ruleset. In the existing netfilter implementation, one has to update the entire rule set in order to make a change and this is very expensive. Userspace tools exist to create nftables rules using existing netfilter rule sets, but both kernel implementations will need to co-exist for quite some time as we transition from the old to the new stuff. Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have worked so hard on this. 2) Daniel Borkmann and Hannes Frederic Sowa made several improvements to our pseudo-random number generator, mostly used for things like UDP port randomization and netfitler, amongst other things. In particular the taus88 generater is updated to taus113, and test cases are added. 3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet and Yang Yingliang. 4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin Sujir. 5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet, Neal Cardwell, and Yuchung Cheng. 6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary control message data, much like other socket option attributes. From Francesco Fusco. 7) Allow applications to specify a cap on the rate computed automatically by the kernel for pacing flows, via a new SO_MAX_PACING_RATE socket option. From Eric Dumazet. 8) Make the initial autotuned send buffer sizing in TCP more closely reflect actual needs, from Eric Dumazet. 9) Currently early socket demux only happens for TCP sockets, but we can do it for connected UDP sockets too. Implementation from Shawn Bohrer. 10) Refactor inet socket demux with the goal of improving hash demux performance for listening sockets. With the main goals being able to use RCU lookups on even request sockets, and eliminating the listening lock contention. From Eric Dumazet. 11) The bonding layer has many demuxes in it's fast path, and an RCU conversion was started back in 3.11, several changes here extend the RCU usage to even more locations. From Ding Tianhong and Wang Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav Falico. 12) Allow stackability of segmentation offloads to, in particular, allow segmentation offloading over tunnels. From Eric Dumazet. 13) Significantly improve the handling of secret keys we input into the various hash functions in the inet hashtables, TCP fast open, as well as syncookies. From Hannes Frederic Sowa. The key fundamental operation is "net_get_random_once()" which uses static keys. Hannes even extended this to ipv4/ipv6 fragmentation handling and our generic flow dissector. 14) The generic driver layer takes care now to set the driver data to NULL on device removal, so it's no longer necessary for drivers to explicitly set it to NULL any more. Many drivers have been cleaned up in this way, from Jingoo Han. 15) Add a BPF based packet scheduler classifier, from Daniel Borkmann. 16) Improve CRC32 interfaces and generic SKB checksum iterators so that SCTP's checksumming can more cleanly be handled. Also from Daniel Borkmann. 17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces using the interface MTU value. This helps avoid PMTU attacks, particularly on DNS servers. From Hannes Frederic Sowa. 18) Use generic XPS for transmit queue steering rather than internal (re-)implementation in virtio-net.

In case of error, the function devm_request_and_ioremap() returns NULL pointer not ERR_PTR(). Fix it by using devm_ioremap_resource() instead of devm_request_and_ioremap().

2013-10-30MIPS: db1235: Don't use MMC_CLKGATEUlf Hansson1-1/+0
As a first step in removing code for MMC_CLKGATE, MIPS db1235 defconfig which is the only current user, shall move away from this option. The mmc host drivers au1xmmc and jz4740_mmc, which are used on MIPS don't support clock gating through MMC_CLKGATE, thus removing the config option will have no effect on power save - clock gating wise.

2013-10-30MIPS: malta: Fix GIC interrupt offsetsMarkos Chandras1-4/+5
The GIC interrupt offsets are calculated based on the value of NR_CPUS. However, this is wrong because NR_CPUS may or may not contain the real number of the actual cpus present in the system. We fix that by using the 'nr_cpu_ids' variable which contains the real number of cpus in the system. Previously, an MT core (eg with 8 VPEs) will fail to boot if NR_CPUS was > 8 with the following errors: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at kernel/irq/chip.c:670 __irq_set_handler+0x15c/0x164() Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Tainted: G W 3.12.0-rc5-00087-gced5633 5 Stack : 00000006 00000004 00000000 00000000 00000000 00000000 807a4f36 00000053 807a0000 00000000 80173218 80565aa8 00000000 00000000 00000000 0000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 0000000 00000000 00000000 00000000 8054fd00 8054fd94 80500514 805657a7 8016eb4 807a0000 80500514 00000000 00000000 80565aa8 8079a5d8 80565766 8054fd0 ...

The PIIX4_ICTLR* and PIIX4_OCW* defines are not used by any other files. Remove them. The only file (other than fixup-malta.c which includes piix4.h in patch #1) containing "#include <asm/mips-boards/piix4.h>" is arch/mips/mti-malta/malta-int.c whose first version is actually "1da177e4c3:arch/mips/mips-boards/malta/malta_int.c".

Always register the R4K clocksource when CONFIG_CSRC_R4K is selected, regardless of selected support for other clocksources. The kernel will select the best clocksource based on their ratings, making it safe to register R4K unconditionally and use it as a fallback should the kernel be run on a system where other selected clocksources are inoperable.
