This driver is used on Microblaze and will be used on Arm Zynq. Microblaze doesn't define NO_IRQ and no IRQ is 0. Arm still uses NO_IRQ as -1 and there is no option to connect IRQ to irq 0.

2013-01-10bnx2x: Allow management traffic after boot from SANBarak Witkowski1-8/+52
As part of the previous driver unload flow, whenever bnx2x is loaded after the UNDI driver it closes all Rx traffic. However, this leads to management traffic also being stopped until the network interface associated with one of its functions gets loaded. To remedy this, management traffic is re-opened once the 'cleaning' after the previous driver ends.

Commit 70ac618c07 ("ptp: fixup Kconfig for two PHC drivers.") removed all dependencies for the blackfin hardware time-stamping Kconfig entry. Hardware time-stamping is only available on BF518 though. Since the Kconfig entry is 'default y', just updateing your kernel source and running `make defconfig` will result in the the following build errors: drivers/net/ethernet/adi/bfin_mac.c:694: error: implicit declaration of function ‘bfin_read_EMAC_PTP_CTL’ drivers/net/ethernet/adi/bfin_mac.c:702: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FV3’ drivers/net/ethernet/adi/bfin_mac.c:712: error: implicit declaration of function ‘bfin_write_EMAC_PTP_CTL’ drivers/net/ethernet/adi/bfin_mac.c:717: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FOFF’ ...

2013-01-10tun: avoid owner checks on IFF_ATTACH_QUEUEMichael S. Tsirkin1-2/+0
At the moment, we check owner when we enable queue in tun. This seems redundant and will break some valid uses where fd is passed around: I think TUNSETOWNER is there to prevent others from attaching to a persistent device not owned by them.

2013-01-10tuntap: refuse to re-attach to different tun_structStefan Hajnoczi1-0/+2
Multiqueue tun devices support detaching a tun_file from its tun_struct and re-attaching at a later point in time. This allows users to disable a specific queue temporarily. ioctl(TUNSETIFF) allows the user to specify the network interface to attach by name. This means the user can attempt to attach to interface "B" after detaching from interface "A". The driver is not designed to support this so check we are re-attaching to the right tun_struct. Failure to do so may lead to oops. Signed-off-by: Stefan Hajnoczi <[email protected]> Acked-by: Jason Wang <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-01-10ipv6: use addrconf_get_prefix_route for prefix route lookup [v2]Romain Kuntz1-14/+11
Replace ip6_route_lookup() with addrconf_get_prefix_route() when looking up for a prefix route. This ensures that the connected prefix is looked up in the main table, and avoids the selection of other matching routes located in different tables as well as blackhole or prohibited entries. In addition, this fixes an Opps introduced by commit 64c6d08e (ipv6: del unreachable route when an addr is deleted on lo), that would occur when a blackhole or prohibited entry is selected by ip6_route_lookup(). Such entries have a NULL rt6i_table argument, which is accessed by __ip6_del_rt() when trying to lock rt6i_table->tb6_lock. The function addrconf_is_prefix_route() is not used anymore and is removed.

2013-01-10drm/i915: Revert shrinker changes from "Track unbound pages"Daniel Vetter1-4/+14
This partially reverts commit 6c085a728cf000ac1865d66f8c9b52935558b328 Author: Chris Wilson <[email protected]> Date: Mon Aug 20 11:40:46 2012 +0200 drm/i915: Track unbound pages Closer inspection of that patch revealed a bunch of unrelated changes in the shrinker: - The shrinker count is now in pages instead of objects. - For counting the shrinkable objects the old code only looked at the inactive list, the new code looks at all bounds objects (including pinned ones). That is obviously in addition to the new unbound list. - The shrinker cound is no longer scaled with sysctl_vfs_cache_pressure. Note though that with the default tuning value of vfs_cache_pressue = 100 this doesn't affect the shrinker behaviour. - When actually shrinking objects, the old code first dropped purgeable objects, then normal (inactive) objects. Only then did it, in a last-ditch effort idle the gpu and evict everything. The new code omits the intermediate step of evicting normal inactive objects. Safe for the first change, which seems benign, and the shrinker count scaling, which is a bit a different story, the endresult of all these changes is that the shrinker is _much_ more likely to fall back to the last-ditch resort of idling the gpu and evicting everything. The old code could only do that if something else evicted lots of objects meanwhile (since without any other changes the nr_to_scan will be smaller than the object count). Reverting the vfs_cache_pressure behaviour itself is a bit bogus: Only dentry/inode object caches should scale their shrinker counts with vfs_cache_pressure. Originally I've had that change reverted, too. But Chris Wilson insisted that it's too bogus and shouldn't again see the light of day. Hence revert all these other changes and restore the old shrinker behaviour, with the minor adjustment that we now first scan the unbound list, then the inactive list for each object category (purgeable or normal). A similar patch has been tested by a few people affected by the gen4/5 hangs which started to appear in 3.7, which some people bisected to the "drm/i915: Track unbound pages" commit. But just disabling the unbound logic alone didn't change things at all. Note that this patch doesn't fix the referenced bugs, it only hides the underlying bug(s) well enough to restore pre-3.7 behaviour. The key to achieve that is to massively reduce the likelyhood of going into a full gpu stall and evicting everything. v2: Reword commit message a bit, taking Chris Wilson's comment into account. v3: On Chris Wilson's insistency, do not reinstate the rather bogus vfs_cache_pressure change.

2013-01-10arm64: mm: introduce present, faulting entries for PAGE_NONEWill Deacon1-11/+13
This is mostly a port of dbf62d50067e ("ARM: mm: introduce L_PTE_VALID for page table entries") and 26ffd0d43b18 ("ARM: mm: introduce present, faulting entries for PAGE_NONE") from ARM, which makes use of present, faulting page table entries for page table entries mapped as PROT_NONE. The main difference with this implementation is that we can make use of the two pte type bits in order to avoid allocating a software bit for identifying PROT_NONE pages, instead reserving the 10b suffix for these types of mappings. This is required to prevent users from accessing such pages via syscalls such as read/write over a pipe.

2013-01-10arm64: vdso: remove broken, redundant sequence counting for timezonesWill Deacon2-6/+0
This patch is an arm64 version of ce73ec6db47a ("powerpc/vdso: Remove redundant locking in update_vsyscall_tz()"). Timezone data is not protected, so the sequence counter is not required to ensure consistency. Furthermore, having multiple paths updating the counter leads to a race between update_vsyscall and update_vsyscall_tz, so remove the timezone sequence counting from both the kernel and the vdso.
