This should cover the final warnings in -rc5 with two more backports from our development branch (drm-intel-next-queued). They're the ones from Daniel and Damien, with references to the reports. This is on top of drm-fixes because of the dependency on the two earlier fixes not yet in Linus' tree. There's an additional regression fix from Chris. * tag 'drm-intel-fixes-2015-03-26' of git://anongit.freedesktop.org/drm-intel: drm/i915: Fixup legacy plane->crtc link for initial fb config drm/i915: Fix atomic state when reusing the firmware fb drm/i915: Keep ring->active_list and ring->requests_list consistent

This is a very similar bug in the load detect code fixed in commit 9128b040 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Mar 3 17:31:21 2015 +0100 drm/i915: Fix modeset state confusion in the load detect code But this time around it was the initial fb code that forgot to update the plane->crtc pointer. Otherwise it's the exact same bug, with the exact same restrains (any set_config call/ioctl that doesn't disable the pipe papers over the bug for free, so fairly hard to hit in normal testing). So if you want the full explanation just go read that one over there - it's rather long ...

If we retire requests last, we may use a later seqno and so clear the requests lists without clearing the active list, leading to confusion. Hence we should retire requests first for consistency with the early return. The order used to be important as the lifecycle for the object on the active list was determined by request->seqno. However, the requests themselves are now reference counted removing the constraint from the order of retirement.

Originally it was impossible to be dropping the last refcount in this function since there was always one around still from the idr. But in commit 83f45fc3 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Aug 6 09:10:18 2014 +0200 drm: Don't grab an fb reference for the idr we've switched to weak references, broke that assumption but forgot to fix it up. Since we still force-disable planes it's only possible to hit this when racing multiple rmfb with fbdev restoring or similar evil things. As long as userspace is nice it's impossible to hit the BUG_ON. But the BUG_ON would most likely be hit from fbdev code, which usually invovles the console_lock besides all modeset locks. So very likely we'd never get the bug reports if this was hit in the wild, hence better be safe than sorry and backport. Spotted by Matt Roper while reviewing other patches.

Firstly, handle zero length calls properly. Believe it or not there are a few of these happening during early boot. Next, we can't just drop to a memcpy() call in the forward copy case where dst <= src. The reason is that the cache initializing stores used in the Niagara memcpy() implementations can end up clearing out cache lines before we've sourced their original contents completely. For example, considering NG4memcpy, the main unrolled loop begins like this: load src + 0x00 load src + 0x08 load src + 0x10 load src + 0x18 load src + 0x20 store dst + 0x00 Assume dst is 64 byte aligned and let's say that dst is src - 8 for this memcpy() call. That store at the end there is the one to the first line in the cache line, thus clearing the whole line, which thus clobbers "src + 0x28" before it even gets loaded. To avoid this, just fall through to a simple copy only mildly optimized for the case where src and dst are 8 byte aligned and the length is a multiple of 8 as well. We could get fancy and call GENmemcpy() but this is good enough for how this thing is actually used.

When the device is powered up, some (older) firmware versions fail to work properly if we send commands before the boot is complete (everything is OK when the device is hot-plugged). The firmware indicates its ready status by putting the link up. Newer firmwares delay the first command so they don't suffer from this problem. They also report the link being always up. Wait for firmware to become ready (link up) before sending any commands and/or data. This also allows lowering CMD_TIMEOUT value to a reasonable time.

Pull ARM fixes from Russell King: "Another few ARM fixes. Fabrice fixed the L2 cache DT parsing to allow prefetch configuration to be specified even when the cache size parsing fails. Laura noticed that the setting of page attributes wasn't working for modules due to is_module_addr() always returning false. Marc Gonzalez (aka Mason) noticed a potential latent bug with the way we read one of the CPUID registers (where we could attempt to read a non-present CPUID register which may fault.) I've fixed an issue where 32-bit DMA masks were failing with memory which extended to the top of physical address space, and I've also added debugging output of the page tables when we hit a data access exception which we don't specifically handle - prompted by the lack of information in a bug report" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: 8313/1: Use read_cpuid_ext() macro instead of inline asm ARM: 8311/1: Don't use is_module_addr in setting page attributes ARM: 8310/1: l2c: Fix prefetch settings dt parsing ARM: dump pgd, pmd and pte states on unhandled data abort faults ARM: dma-api: fix off-by-one error in __dma_supported()

If ->run() fails, it can either free the data structures it allocated, or leave that task to ->free() which will be called on failures. However: md.c calls ->free() even if ->private_data is NULL, which causes problems in some personalities. raid0.c frees the data, but doesn't clear ->private_data, which will become a problem when we fix md.c So better fix both these issues at once.

Commit db31c55a (net: clamp ->msg_namelen instead of returning an error) introduced the clamping of msg_namelen when the unsigned value was larger than sizeof(struct sockaddr_storage). This caused a msg_namelen of -1 to be valid. The native code was subsequently fixed by commit dbb490b9 (net: socket: error on a negative msg_namelen). In addition, the native code sets msg_namelen to 0 when msg_name is NULL. This was done in commit (6a2a2b3a net:socket: set msg_namelen to 0 if msg_name is passed as NULL in msghdr struct from userland) and subsequently updated by 08adb7da (fold verify_iovec() into copy_msghdr_from_user()). This patch brings the get_compat_msghdr() in line with copy_msghdr_from_user(). Fixes: db31c55a (net: clamp ->msg_namelen instead of returning an error) Cc: David S.

Sathya Perla says: ==================== be2net: patch set Hi David, this patch set includes 3 bug fixes to the be2net driver. Patch 1 fixes a vlan isolation issue with VFs. When a VF is placed in promiscous mode, it could receive packets belonging to any vlan, as the PF driver grants vlan promisc capability to VFs. The PF driver now disables the vlan promisc capability for VFs to fix this problem. Patch 2 fixes the call to MODIFY_EQ_DELAY FW cmd to not include more than 8 EQs per cmd. The FW is not capable of handling more than 8 EQs per cmd. Patch 3 fixes an EEH error detection issue. On Power platforms, when an EEH error occurs, the slot disconnect state is more reliably detected via an MMIO read compared to a config read. So, the error register reads that occur every second are now done via MMIO. Pls apply this patch set to the "net" tree. Thanks! ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When an EEH error occurs, the device/slot is disconnected. This condition is more reliably detected (i.e., returns all ones) with an MMIO read rather than a config read -- especially on power platforms. Hence, this patch fixes EEH error detection by replacing config reads with MMIO reads for reading the error registers. The error registers in Skyhawk-R/BE2/BE3 are accessible both via the config space and the PCICFG (BAR0) memory space.

Currently, a PF does not restrict its VF interface from enabling vlan promiscuous mode. This breaks vlan isolation when a vlan (transparent tagging) is configured on a VF.
