2016-02-08xen/arm: correctly handle DMA mapping of compound pagesIan Campbell
Currently xen_dma_map_page concludes that DMA to anything other than the head page of a compound page must be foreign, since the PFN of the page is that of the head. Fix the check to instead consider the whole of a compound page to be local if the PFN of the head passes the 1:1 check. We can never see a compound page which is a mixture of foreign and local sub-pages. The comment already correctly described the intention, but fixup the spelling and some grammar. This fixes the various SSH protocol errors which we have been seeing on the cubietrucks in our automated test infrastructure. This has been broken since commit 3567258d281b ("xen/arm: use hypercall to flush caches in map_page"), which was in v3.19-rc1. NB arch/arm64/.../xen/page-coherent.h also includes this file.

2016-02-08xen/scsiback: avoid warnings when adding multiple LUNs to a domainJuergen Gross
When adding more than one LUN to a frontend a warning for a failed assignment is issued in dom0 for each already existing LUN. Avoid this warning by checking for a LUN already existing when existence is allowed (scsiback_do_add_lun() called with try == 1). As the LUN existence check is needed now for a third time, factor it out into a function. This in turn leads to a more or less complete rewrite of scsiback_del_translation_entry() which will now return a proper error code in case of failure.

2016-02-08ARM: 8517/1: ICST: avoid arithmetic overflow in icst_hz()Linus Walleij
When trying to set the ICST 307 clock to 25174000 Hz I ran into this arithmetic error: the icst_hz_to_vco() correctly figure out DIVIDE=2, RDW=100 and VDW=99 yielding a frequency of 25174000 Hz out of the VCO. (I replicated the icst_hz() function in a spreadsheet to verify this.) However, when I called icst_hz() on these VCO settings it would instead return 4122709 Hz. This causes an error in the common clock driver for ICST as the common clock framework will call .round_rate() on the clock which will utilize icst_hz_to_vco() followed by icst_hz() suggesting the erroneous frequency, and then the clock gets set to this. The error did not manifest in the old clock framework since this high frequency was only used by the CLCD, which calls clk_set_rate() without first calling clk_round_rate() and since the old clock framework would not call clk_round_rate() before setting the frequency, the correct values propagated into the VCO. After some experimenting I figured out that it was due to a simple arithmetic overflow: the divisor for 24Mhz reference frequency as reference becomes 24000000*2*(99+8)=0x132212400 and the "1" in bit 32 overflows and is lost. But introducing an explicit 64-by-32 bit do_div() and casting the divisor into (u64) we get the right frequency back, and the right frequency gets set. Tested on the ARM Versatile.

2016-02-08ALSA: timer: Fix wrong instance passed to slave callbacksTakashi Iwai
In snd_timer_notify1(), the wrong timer instance was passed for slave ccallback function. This leads to the access to the wrong data when an incompatible master is handled (e.g. the master is the sequencer timer and the slave is a user timer), as spotted by syzkaller fuzzer. This patch fixes that wrong assignment.

2016-02-08unix: correctly track in-flight fds in sending process user_structHannes Frederic Sowa
The commit referenced in the Fixes tag incorrectly accounted the number of in-flight fds over a unix domain socket to the original opener of the file-descriptor. This allows another process to arbitrary deplete the original file-openers resource limit for the maximum of open files. Instead the sending processes and its struct cred should be credited. To do so, we add a reference counted struct user_struct pointer to the scm_fp_list and use it to account for the number of inflight unix fds.

2016-02-08irqchip/atmel-aic: Handle aic_common_irq_fixup in aic_common_of_initMilo Kim
AIC IRQ fixup is handled in each IRQ chip driver. It can be moved into aic_common_of_init() before returning the result. Then, aic_common_irq_fixup() can be changed to static type.

2016-02-08spi: Allow compile test of bcm2835aux if !GPIOLIBGeert Uytterhoeven
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency of SPI_BCM2835AUX on GPIOLIB if COMPILE_TEST is enabled. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-02-08netfilter: tee: select NF_DUP_IPV6 unconditionallyArnd Bergmann
The NETFILTER_XT_TARGET_TEE option selects NF_DUP_IPV6 whenever IP6_NF_IPTABLES is enabled, and it ensures that it cannot be builtin itself if NF_CONNTRACK is a loadable module, as that is a dependency for NF_DUP_IPV6. However, NF_DUP_IPV6 can be enabled even if IP6_NF_IPTABLES is turned off, and it only really depends on IPV6. With the current check in tee_tg6, we call nf_dup_ipv6() whenever NF_DUP_IPV6 is enabled. This can however be a loadable module which is unreachable from a built-in xt_TEE: net/built-in.o: In function `tee_tg6': :(.text+0x67728): undefined reference to `nf_dup_ipv6' The bug was originally introduced in the split of the xt_TEE module into separate modules for ipv4 and ipv6, and two patches tried to fix it unsuccessfully afterwards. This is a revert of the the first incorrect attempt to fix it, going back to depending on IPV6 as the dependency, and we adapt the 'select' condition accordingly.
