2012-03-28Merge tag 'drivers2' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull "ARM: More SoC driver updates" from Olof Johansson: "This branch contains a handful of driver updates, mostly to the LPC32xx platform but also for Samsung EXYNOS and Davinci. It had a few context conflicts against patches already merged through fixes-non-critical. We should have resolved this early during the development cycle by pulling them in as a dependency, instead I did it after the fact this time." * tag 'drivers2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: gpio/samsung: use ioremap() for EXYNOS4 GPIOlib gpio/samsung: add support GPIOlib for EXYNOS5250 ARM: EXYNOS: add support GPIO for EXYNOS5250 ARM: LPC32xx: Ethernet support ARM: LPC32xx: USB Support ARM: davinci: dm644x evm: add support for VPBE display ARM: davinci: dm644x: add support for v4l2 video display ARM: EXYNOS: Hook up JPEG PD to generic PD infrastructure ARM: EXYNOS: Hook up G2D PD to generic PD infrastructure arm: lpc32xx: phy3250: add rtc & touch device ARM: LPC32xx: clock.c: Clock registration fixes ARM: LPC32xx: clock.c: jiffies wrapping ARM: LPC32xx: clock.c: Missing header file ARM: LPC32XX: Remove broken non-static declaration ARM: LPC32xx: clock.c: Fix mutex lock issues ARM: LPC32xx: clock.c: warning fix ARM: LPC32xx: Added lpc32xx_defconfig
2012-03-28x86/apic/amd: Be more verbose about LVT offset assignmentsRobert Richter
Add information about LVT offset assignments to better debug firmware bugs related to this. See following examples. # dmesg | grep -i 'offset\|ibs' LVT offset 0 assigned for vector 0xf9 [Firmware Bug]: cpu 0, try to use APIC500 (LVT offset 0) for vector 0x10400, but the register is already in use for vector 0xf9 on another cpu [Firmware Bug]: cpu 0, IBS interrupt offset 0 not available (MSRC001103A=0x0000000000000100) Failed to setup IBS, -22 In this case the BIOS assigns both offsets for MCE (0xf9) and IBS (0x400) vectors to offset 0, which is why the second APIC setup (IBS) failed. With correct setup you get: # dmesg | grep -i 'offset\|ibs' LVT offset 0 assigned for vector 0xf9 LVT offset 1 assigned for vector 0x400 IBS: LVT offset 1 assigned perf: AMD IBS detected (0x00000007) oprofile: AMD IBS detected (0x00000007) Note: The vector includes also the message type to handle also NMIs (0x400). In the firmware bug message the format is the same as of the APIC500 register and includes the mask bit (bit 16) in addition.

2012-03-28sh: Avoid exporting unimplemented syscalls.Paul Mundt
Now that userspace is making use of kernel-provided sanitized headers for working out supported interfaces, we need to be a bit more diligent with matching the syscall definitions with their actual wiring/support state. In theory it shouldn't hurt anything since sys_ni_syscall will ultimately do the right thing, but there's also not much need to lie about legacy x86 syscalls that we've never supported. This tightens things up a bit for uClibc at least. Suggested-by: Carmelo Amoroso <carmelo.amoroso@st.com> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
