2013-06-03ipv4: use separate genid for next hop exceptionsTimo Teräs
commit 13d82bf5 (ipv4: Fix flushing of cached routing informations) added the support to flush learned pmtu information. However, using rt_genid is quite heavy as it is bumped on route add/change and multicast events amongst other places. These can happen quite often, especially if using dynamic routing protocols. While this is ok with routes (as they are just recreated locally), the pmtu information is learned from remote systems and the icmp notification can come with long delays. It is worthy to have separate genid to avoid excessive pmtu resets. Cc: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: David S.

2013-06-03ipv4: rate limit updating of next hop exceptions with same pmtuTimo Teräs

This reverts commit 05ab86c5 (xfrm4: Invalidate all ipv4 routes on IPsec pmtu events). Flushing all cached entries is not needed. Instead, invalidate only the related next hop dsts to recheck for the added next hop exception where needed. This also fixes a subtle race due to bumping generation id's before updating the pmtu.

2013-06-02ARM: bcm2835: override the HW UART periphidJongsung Kim
Stephen Warren reported the recent commit 78506f2 (add support for extended FIFO-size of PL011-r1p5) breaks the serial port on the BCM2835 ARM SoC. A UART compatible with the ARM PL011-r1p5 should have 32-deep FIFOs. The BCM2835 UART just looks like an ARM PL011-r1p5, but has 16-deep FIFOs just like PL011-r1p4 or earlier revisions. As a workaround for this compatibility issue, this patch overrides the HW UART periphid register values with the actually compatible UART periphid 0x00241011 (r1p3 or r1p4).

2013-06-02sata_rcar: fix interrupt handlingSergei Shtylyov
The driver's interrupt handling code is too picky in deciding whether it should handle an interrupt or not which causes completely unneeded spurious interrupts. Thus make sata_rcar_{ata|serr}_interrupt() *void*; add ATA status register read to sata_rcar_ata_interrupt() to clear an unexpected ATA interrupt -- it doesn't get cleared by writing to the SATAINTSTAT register in the interrupt mode we use. Also, in sata_rcar_ata_interrupt() we should check SATAINTSTAT register only for enabled interrupts and we should clear only those interrupts that we have read as active first time around, because else we have a race and risk clearing an interrupt that can occur between read and write of the SATAINTSTAT register and never registering it...

2013-06-01parisc: memory overflow, 'name' length is too short for usingChen Gang
'path.bc[i]' can be asigned by PCI_SLOT() which can '> 10', so sizeof(6 * "%u:" + "%u" + '\0') may be 21. Since 'name' length is 20, it may be memory overflow. And 'path.bc[i]' is 'unsigned char' for printing, we can be sure the max length of 'name' must be less than 28. So simplify thinking, we can use 28 instead of 20 directly, and do not think of whether 'patchc.bc[i]' can '> 100'.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull powerpc fixes from Ben Herrenschmidt: "Here are a few more fixes for powerpc 3.10. It's a bit more than I would have liked this late in the game but I suppose that's what happens with a brand new chip generation coming out. A few regression fixes, some last minute fixes for new P8 features such as transactional memory,... There's also one powerpc KVM patch that I requested that adds two missing functions to our in-kernel interrupt controller support which is itself a new 3.10 feature. These are defined by the base hypervisor specification. We didn't implement them originally because Linux doesn't use them but they are simple and I'm not comfortable having a half-implemented interface in 3.10 and having to deal with versionning etc... later when something starts needing those calls. They cannot be emulated in qemu when using in-kernel interrupt controller (not enough shared state). Just added a last minute patch to fix a typo introducing a breakage in our cputable for Power7+ processors, sorry about that, but the regression it fixes just hurt me :-)" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc/cputable: Fix typo on P7+ cputable entry powerpc/perf: Add missing SIER support powerpc/perf: Revert to original NO_SIPR logic powerpc/pci: Remove the unused variables in pci_process_bridge_OF_ranges powerpc/pci: Remove the stale comments of pci_process_bridge_OF_ranges powerpc/pseries: Always enable CONFIG_HOTPLUG_CPU on PSERIES SMP powerpc/kvm/book3s: Add support for H_IPOLL and H_XIRR_X in XICS emulation powerpc/32bit:Store temporary result in r0 instead of r8 powerpc/mm: Always invalidate tlb on hpte invalidate and update powerpc/pseries: Improve stream generation comments in copypage/user powerpc/pseries: Kill all prefetch streams on context switch powerpc/cputable: Fix oprofile_cpu_type on power8 powerpc/mpic: Fix irq distribution problem when MPIC_SINGLE_DEST_CPU powerpc/tm: Fix userspace stack corruption on signal delivery for active transactions powerpc/tm: Move TM abort cause codes to uapi powerpc/tm: Abort on emulation and alignment faults powerpc/tm: Update cause codes documentation powerpc/tm: Make room for hypervisor in abort cause codes
