I debated whether or not to send you this merge request because we're at such a late rc. The bug isn't critical in that there is only one system known to be affected and the patch is easy to backport. The codepath is used by pretty much every DT based system, so there is risk a of regression (it /should/ be safe, but I've been bitten by stuff that should be safe before). I've had it in linux-next for a week and haven't received any complaints. I think it probably should just be merged right away rather than waiting for the merge window and backporting. It does fix a real bug and the code is theoretically safer after the change. I can't think of any situation where it would be dangerous to reserve the DT memory an extra time. Summary from tag: Single bugfix for boot failure seen in the wild. The memory reserve code tries to be clever about reserving the FDT, but it should just go ahead and reserve it unconditionally to avoid the problem of partial overlap described in the patch" * tag 'devicetree-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux: of/fdt: memblock_reserve /memreserve/ regions in the case of partial overlap

2014-12-02xen-netfront: Remove BUGs on paged skb data which crosses a page boundarySeth Forshee
These BUGs can be erroneously triggered by frags which refer to tail pages within a compound page. The data in these pages may overrun the hardware page while still being contained within the compound page, but since compound_order() evaluates to 0 for tail pages the assertion fails. The code already iterates through subsequent pages correctly in this scenario, so the BUGs are unnecessary and can be removed.

Indications are that no GF116's actually have a copy engine there, but actually have the decompression engine. This engine can be made to do copies, but that should be done separately. Unclear why this didn't turn up on all GF116's, but perhaps the non-mobile ones came with enough VRAM to not trigger ttm migrations in test scenarios.

2014-12-01PCI: tegra: Use physical range for I/O mappingThierry Reding
Commit 0b0b0893d49b ("of/pci: Fix the conversion of IO ranges into IO resources") changed how I/O resources are parsed from DT. Rather than containing the physical address of the I/O region, the addresses will now be in I/O address space. On Tegra the union of all ranges is used to expose a top-level memory- mapped resource for the PCI host bridge. This helps to make /proc/iomem more readable. Combining both of the above, the union would now include the I/O space region. This causes a regression on Tegra20, where the physical base address of the PCIe controller (and therefore of the union) is located at physical address 0x80000000. Since I/O space starts at 0, the union will now include all of system RAM which starts at 0x00000000. This commit fixes this by keeping two copies of the I/O range: one that represents the range in the CPU's physical address space, the other for the range in the I/O address space. This allows the translation setup within the driver to reuse the physical addresses. The code registering the I/O region with the PCI core uses both ranges to establish the mapping.

And also, in the current implementation, buffer alignment method by sh_eth_set_receive_align function has a bug that this function displace buffer start address forcedly when the alignment is corrected.

Most of these are fairly standard little fixes, a bmc150 and bmg160 patch is to make an ABI change to indicated a specific axis in an event rather than the generic option in the original drivers. As both of these drivers are new in this cycle it would be ideal to push this minor change through even though it isn't strictly a fix. A couple of other 'fixes' change defaults for some settings on these new drivers to more intuitive calues. Looks like some useful feedback has been coming in for this driver since it was applied. * IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while 0xCF clearly doesn't give a contiguous bitmask. * kxcjk-1013 range setting was failing to mask out the previous value in the register and hence was 'enable only'. * men_z188 device id table wasn't null terminated. * bmg160 and bmc150 both failed to correctly handling an error in mode setting. * bmg160 and bmc150 both had a bug in setting the event direction in the event spec (leads to an attribute name being incorrect) * bmg160 defaulted to an open drain output for the interrupt - as a default this obviously only works with some interrupt chips - hence change the default to push-pull (note this is a new driver so we aren't going to cause any regressions with this change). * bmc150 had an unintuitive default for the rate of change (motion detector) so change it to 0 (new driver so change of default won't cause any regressions).

2014-11-26net/mlx4_core: Limit count field to 24 bits in qp_alloc_resJack Morgenstein
Some VF drivers use the upper byte of "param1" (the qp count field) in mlx4_qp_reserve_range() to pass flags which are used to optimize the range allocation. Under the current code, if any of these flags are set, the 32-bit count field yields a count greater than 2^24, which is out of range, and this VF fails. As these flags represent a "best-effort" allocation hint anyway, they may safely be ignored. Therefore, the PF driver may simply mask out the bits.

Our boot agent may have left the switch in an certain configuration state, make sure we issue a software reset prior to configuring the switch in order to ensure the HW is in a consistent state, in particular transmit queues and internal buffers.

In case we fail to ioremap() one of our registers, we would be leaking existing mappings, unwind those accordingly on errors. Fixes: 246d7f773c13 ("net: dsa: add Broadcom SF2 switch driver") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-26of/fdt: memblock_reserve /memreserve/ regions in the case of partial overlapIan Campbell
memblock_is_region_reserved() returns true in the case of a partial overlap, meaning that the current code fails to reserve the non-overlapping portion. This call was introduced as part of d1552ce449eb "of/fdt: move memreserve and dtb memory reservations into core" which went into v3.16. I observed this causing a Midway system with a buggy fdt (the header declares itself to be larger than it really is) failing to boot because the over-inflated size of the fdt was causing it to seem to run into the swapper_pg_dir region, meaning the DT wasn't reserved. The symptoms were failing to find an disks or network and failing to boot. However given the ambiguity of whether things like the initrd are covered by /memreserve/ and similar I think it is best to also register the region rather than just ignoring it. Since memblock_reserve() handles overlaps just fine lets just warn and carry on.
