Commit 9f9c9cbb6057 ("drivers/firmware/dmi_scan.c: fetch dmi version from SMBIOS if it exists") hoisted the check for "_DMI_" into dmi_scan_machine(), which means that we don't bother to check for "_DMI_" at offset 16 in an SMBIOS entry. smbios_present() may also call dmi_present() for an address where we found "_SM_", if it failed further validation.

2013-03-08idr: remove WARN_ON_ONCE() on negative IDsTejun Heo1-13/+3
idr_find(), idr_remove() and idr_replace() used to silently ignore the sign bit and perform lookup with the rest of the bits. The weird behavior has been changed such that negative IDs are treated as invalid. As the behavior change was subtle, WARN_ON_ONCE() was added in the hope of determining who's calling idr functions with negative IDs so that they can be examined for problems. Up until now, all two reported cases are ID number coming directly from userland and getting fed into idr_find() and the warnings seem to cause more problems than being helpful. Drop the WARN_ON_ONCE()s.

2013-03-08arm: plat-orion: fix address decoding when > 4GB is usedThomas Petazzoni1-2/+5
During the system initialization, the orion_setup_cpu_mbus_target() function reads the SDRAM address decoding registers to find out how many chip-selects of SDRAM have been enabled, and builds a small array with one entry per chip-select. This array is then used by device drivers (XOR, Ethernet, etc.) to configure their own address decoding windows to the SDRAM. However, devices can only access the first 32 bits of the physical memory. Even though LPAE is not supported for now, some Marvell boards are now showing up with 8 GB of RAM, configured using two SDRAM address decoding windows: the first covering the first 4 GB, the second covering the last 4 GB. The array built by orion_setup_cpu_mbus_target() has therefore two entries, and device drivers try to set up two address decoding windows to the SDRAM. However, in the device registers for the address decoding, the base address is only 32 bits, so those two windows overlap each other, and the devices do not work at all. This patch makes sure that the array built by orion_setup_cpu_mbus_target() only contains the SDRAM decoding windows that correspond to the first 4 GB of the memory. To do that, it ignores the SDRAM decoding windows for which the 4 low-order bits are not zero (the 4 low-order bits of the base register are used to store bits 32:35 of the base address, so they actually indicate whether the base address is above 4 GB). This patch allows the newly introduced armada-xp-gp board to properly operate when it is mounted with more than 4 GB of RAM. Without that, all devices doing DMA (for example XOR and Ethernet) do not work at all.

2013-03-08arm: mvebu: Reduce reg-io-width with UARTsHeikki Krogerus2-4/+4
Setting the reg-io-width to 1 byte represents more accurate description of the HW. This will fix an issue where UART driver causes kernel panic during bootup. Gregory CLEMENT traced the issue to autoconfig() in 8250.c, where the existence of FIFO is checked from UART_IIR register. The register is now read as 32-bit value as the reg-io-width is set to 4-bytes. The retuned value seems to contain bogus data for bits 31:8, causing the issue.

2013-03-08ARM: kirkwood: fix to retain gbe MAC addresses for DT kernelsSebastian Hesselbarth1-7/+18
The ethernet controller used on kirkwood looses its MAC address register contents when the corresponding clock is gated. As soon as mv643xx_eth is built as module, the clock gets gated and when loading the module, the MAC address is gone. Proper DT support for the mv643xx_eth driver is expected soon, so we add a workaround to always enable ge0/ge1 clocks on kirkwood. This workaround is also already used on non-DT kirkwood kernels.

2013-03-08ARM: kirkwood: of_serial: fix clock gating by removing clock-frequencyJason Cooper17-20/+0
When DT support for kirkwood was first introduced, there was no clock infrastructure. As a result, we had to manually pass the clock-frequency to the driver from the device node. Unfortunately, on kirkwood, with minimal config or all module configs, clock-frequency breaks booting because of_serial doesn't consume the gate_clk when clock-frequency is defined. The end result on kirkwood is that runit gets gated, and then the boot fails when the kernel tries to write to the serial port. Fix the issue by removing the clock-frequency parameter from all kirkwood dts files. Booted on dreamplug without earlyprintk and successfully logged in via ttyS0.

2013-03-08tg3: Update link_up flag for phylib devicesNithin Sujir1-9/+5
Commit f4a46d1f46a8fece34edd2023e054072b02e110d introduced a bug where the ifconfig stats would remain 0 for phylib devices. This is due to tp->link_up flag never becoming true causing tg3_periodic_fetch_stats() to return. The link_up flag was being updated in tg3_test_and_report_link_chg() after setting up the phy. This function however, is not called for phylib devices since the driver does not do the phy setup. This patch moves the link_up flag update into the common tg3_link_report() function that gets called for phylib devices as well for non phylib devices when the link state changes. To avoid updating link_up twice, we replace tg3_carrier_...() calls that are followed by tg3_link_report(), with netif_carrier_...(). We can then remove the unused tg3_carrier_on() function.

This is really difficult to test with real NFC devices, but without this fix an LLCP server will eventually refuse new connections. Signed-off-by: Samuel Ortiz <[email protected]>
2013-03-08mtd: bcm47xxpart: look for NVRAM at the end of deviceRafał Miłecki1-7/+25
NVRAM is always placed at the end of device and it does not have to start at the beginning of a block, so check few possible offsets. Signed-off-by: Rafał Miłecki <[email protected]> Signed-off-by: David Woodhouse <[email protected]>
2013-03-08Revert "mtd: bcm47xxpart: improve probing of nvram partition"Rafał Miłecki1-13/+9
This reverts commit be3781b71ac03723b552dc156931620634ef1b22. Some CFE bootloaders have NVRAM at offset 0x1000. With that patch we were detecting such a bootloaders as a standard NVRAM partition. Changing anything in this pseudo-NVRAM resulted in corrupted bootloader and bricked device! Signed-off-by: Rafał Miłecki <[email protected]> Signed-off-by: David Woodhouse <[email protected]>
2013-03-08tracing: update documentation of snapshot utilityHiraku Toyooka1-1/+1
Now, "snapshot" file returns success on a reset of snapshot buffer even if the buffer wasn't allocated, instead of returning EINVAL. This patch updates snapshot desctiption according to the change.

sizeof (cmd.parm.cmsg.para) is 50 (MAX_CAPI_PARA_LEN). sizeof (cmd.parm) is 80+, but less than 100. strlen(msg) may be more than 80+ (Modem-Commandbuffer, less than 255). isdn_tty_send_msg is called by isdn_tty_parse_at the relative parameter is m->mdmcmd (atemu *m) the relative command may be "+M..." so need check the length to be sure not memory overflow. cmd.parm is a union, and need keep original valid buffer length no touch Signed-off-by: Chen Gang <[email protected]> Signed-off-by: David S.

2013-03-08bnx2x: Fix SFP+ misconfiguration in iSCSI boot scenarioYaniv Rosner2-1/+6
Fix a problem in which iSCSI-boot installation fails when switching SFP+ boot port and moving the SFP+ module prior to boot. The SFP+ insertion triggers an interrupt which configures the SFP+ module wrongly before interface is loaded.

2013-03-08bnx2x: Fix intermittent long KR2 link up timeYaniv Rosner2-1/+13
When a KR2 device is connected to a KR link-partner, sometimes it requires disabling KR2 for the link to come up. To get a KR2 link up later, in case no base pages are seen, the KR2 is restored. The problem was that some link partners cleared their advertised BP/NP after around two seconds, causing the driver to disable/enable KR2 link all the time. The fix was to wait at least 5 seconds before checking KR2 recovery. Signed-off-by: Yaniv Rosner <[email protected]> Signed-off-by: Eilon Greenstein <[email protected]> Signed-off-by: David S.

2013-03-08virtio: rng: disallow multiple device registrations, fixes crashesAmit Shah1-2/+11
The code currently only supports one virtio-rng device at a time. Invoking guests with multiple devices causes the guest to blow up. Check if we've already registered and initialised the driver. Also cleanup in case of registration errors or hot-unplug so that a new device can be used.
