2014-09-07NFC: st21nfca: Fix potential depmod dependency cycleChristophe Ricard
In the previous makefile 2 modules were generated for CONFIG_NFC_ST21NFCA (st21nfca.ko and st21nfca_dep.ko). Merge both of them into st21nfca_hci.ko and fix a potential depmod dependency cycle, similar to the one we saw on st21nfcb: depmod: WARNING: found 6 modules in dependency cycles! depmod: WARNING: /lib/modules/3.17.0-rc3-00002-g7505cea/kernel/drivers/nfc/st21nfcb/st21nfcb.ko in dependency cycle! depmod: WARNING: /lib/modules/3.17.0-rc3-00002-g7505cea/kernel/drivers/nfc/st21nfcb/ndlc.ko in dependency cycle! depmod: WARNING: /lib/modules/3.17.0-rc3-00002-g7505cea/kernel/net/rfkill/rfkill.ko in dependency cycle! depmod: WARNING: /lib/modules/3.17.0-rc3-00002-g7505cea/kernel/net/nfc/nfc.ko in dependency cycle! depmod: WARNING: /lib/modules/3.17.0-rc3-00002-g7505cea/kernel/net/nfc/nci/nci.ko in dependency cycle! depmod: WARNING: /lib/modules/3.17.0-rc3-00002-g7505cea/kernel/lib/crc-ccitt.ko in dependency cycle! ./scripts/depmod.sh: line 57: 23387 Segmentation fault (core dumped) "$DEPMOD" "$@" "$KERNELRELEASE" $SYMBOL_PREFIX make: *** [_modinst_post] Error 139 Reported-by: Daniel Wagner <wagi@monom.org> Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2014-09-05amd-xgbe: Enable interrupts for all management countersLendacky, Thomas
As the management counters reach a threshold they will generate an interrupt so the value can be saved and the counter reset. The current code does not enable this interrupt on all counters. This can result in inaccurate statistics. Update the code to enable all the counters to generate an interrupt when its threshold is exceeded.

2014-09-05amd-xgbe: Treat certain counter registers as 64 bitLendacky, Thomas
Even if the management counters are configured to be 32 bit register values, the [rt]xoctetcount_gb and [rt]xoctetcount_g counters are always 64 bit counter registers. Since they are not being treated as 64 bit values, these statistics are being reported incorrectly (ifconfig, ethtool, etc.). Update the routines used to read the registers to access the "hi" register (an offset of 4 from the "lo" register) to create a 64 bit value for these 64 bit counters.

2014-09-05greth: moved TX ring cleaning to NAPI rx poll funcDaniel Hellstrom
This patch does not affect the 10/100 GRETH MAC. Before all GBit GRETH TX descriptor ring cleaning was done in start_xmit(), when descriptor list became full it activated TX interrupt to start the NAPI rx poll function to do TX ring cleaning. With this patch the TX descriptor ring is always cleaned from the NAPI rx poll function, triggered via TX or RX interrupt. Otherwise we could end up in TX frames being sent but not reported to the stack being sent. On the 10/100 GRETH this is not an issue since the SKB is copied&aligned into private buffers so that the SKB can be freed directly on start_xmit() Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Signed-off-by: David S.

It seems on 32 bit kernels page_address() can reutrn a NULL value in some circumstances, and the pci_map_single api isn't prepared to handle that (on this system it results in a bogus pointer deference in nommu_map_page. The fix is pretty easy, if we convert the 3c59x driver to use the more convieient skb_frag_dma_map api we don't need to find the virtual address of the page at all, and page gets mapped to the hardware properly.

2014-09-05usb: dwc3: fix TRB completion when multiple TRBs are startedFelipe Balbi
After commit 2ec2a8be (usb: dwc3: gadget: always enable IOC on bulk/interrupt transfers) we created a situation where it was possible to hang a bulk/interrupt endpoint if we had more than one pending request in our queue and they were both started with a single Start Transfer command. The problems triggers because we had not enabled Transfer In Progress event for those endpoints and we were not able to process early giveback of requests completed without LST bit set. Fix the problem by finally enabling Xfer In Progress event for all endpoint types, except control.

2014-09-04PCI: imx6: Put LTSSM in "Detect" state before disabling itLucas Stach
This fixes a boot hang observed when the bootloader already enabled the PCIe link for its own use. The fundamental problem is that Freescale forgot to wire up the core reset, so software doesn't have a sane way to get the core into a defined state. According to the DW PCIe core reference manual, configuration of the core may only happen when the LTSSM is disabled, so this is one of the first things we need to do. Apparently this isn't safe to do when the LTSSM is in any state other than "detect" as we observe an instant machine hang when trying to do so while the link is already up. As a workaround, force LTSSM into detect state right before hitting the disable switch. There is still a race window because the LTSSM may transition out of "detect" before we can disable it, but it's the best we can do for now.

2014-09-04xen/gntalloc: safely delete grefs in add_grefs() undo pathDavid Vrabel
If a gref could not be added (perhaps because the limit has been reached or there are no more grant references available), the undo path may crash because __del_gref() frees the gref while it is being used for a list iteration. A comment suggests that using list_for_each_entry() is safe since the gref isn't removed from the list being iterated over, but it is freed and thus list_for_each_entry_safe() must be used. Also, explicitly delete the gref from the local per-file list, even though this is not strictly necessary.
