* MIPS: BCM63XX: select BOOT_RAWFlorian Fainelli2013-07-01
| | | | | | | | | | | | | | Enabling BOOT_RAW is mandatory to get a binary image (objcopy from ELF to binary) to work. This does not affect the ELF kernels which are used by CFE on BCM63XX DSL platforms, but is going to be necessary to support BCM63XX on Cable Modem chips such as BCM3368.

* MIPS: r4k,octeon,r2300: stack protector: change canary per taskGregory Fong2013-07-01
| | | | | | | | | | | | | | | | | | | For non-SMP, uses the new random canary value that is stored in the task struct whenever a new task is forked. Based on ARM version in df0698be14c6683606d5df2d83e3ae40f85ed0d9 and subject to the same limitations: the variable GCC expects, __stack_chk_guard, is global, so this will not work on SMP. Quoting Nicolas Pitre <nico@fluxnic.net>: "One way to overcome this GCC limitation would be to locate the __stack_chk_guard variable into a memory page of its own for each CPU, and then use TLB locking to have each CPU see its own page at the same virtual address for each of them."

* MIPS: Boot: Compressed: Remove -fstack-protector from CFLAGSMarkos Chandras2013-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building with -fstack-protector, gcc emits the __stack_chk_guard and __stack_chk_fail symbols to check for stack stability. These symbols are defined in vmlinux but the generated vmlinux.bin that is used to create the compressed vmlinuz image has no symbol table so the linker can't find these symbols during the final linking phase. As a result of which, we need either to redefine these symbols just for the compressed image or drop the -fstack-protector option when building the compressed image. This patch implements the latter of two options. Fixes the following linking problem: dbg.c:(.text+0x7c): undefined reference to `__stack_chk_guard' dbg.c:(.text+0x80): undefined reference to `__stack_chk_guard' dbg.c:(.text+0xd4): undefined reference to `__stack_chk_guard' dbg.c:(.text+0xec): undefined reference to `__stack_chk_fail' [ralf@linux-mips.org: I'm applying this before the patch that actually adds stack protector support for MIPS. This means, it will not be possible to trigger above error message with any commit from the tree but rather they are what one would hit without this commit.] Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-mips@linux-mips.org Cc: Markos Chandras <markos.chandras@imgtec.com> Patchwork: https://patchwork.linux-mips.org/patch/5575/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* MIPS: MSP71xx: Remove gpio driversPaul Bolle2013-06-17
| | | | | | | | | | | | | | | | | | The PMC MSP71XX gpio drivers were added in v2.6.28, see commit 9fa32c6b02 ("MIPS: PMC MSP71XX gpio drivers"). They are only built if CONFIG_HAVE_GPIO_LIB is set. But the Kconfig symbol HAVE_GPIO_LIB was already removed in v2.6.27, see commit 7444a72eff ("gpiolib: allow user-selection"). So these drivers were never buildable. Perhaps no-one noticed because there are no in tree users of msp71xx_init_gpio() and msp71xx_init_gpio_extended(). Anyhow, these drivers can safely be removed.

* MIPS: Netlogic: Fix plat_irq_dispatchJayachandran C2013-06-13
| | | | | | | | | | | | | | | | | | Fix an issue in plat_irq_dispatch due to which it can call do_IRQ with a PIC irq that is not mapped. When a per-cpu interrupt and a PIC interrupt are both active, the check 'eirr & PERCPU_IRQ_MASK' will be true, but the interrupt in 'i' will be the number of the PIC interrupt. In this case, we will call do_IRQ on the PIC interrupt without mapping it with nlm_irq_to_xirq(). Fix this by using __ffs64 instead of __ilog2_u64 and using the interrupt number instead of mask to identify per-cpu interrupts.

* MIPS: OCTEON: Rename Kconfig CAVIUM_OCTEON_REFERENCE_BOARD to CAVIUM_OCTEON_SOCDavid Daney2013-06-10
| | | | | | | | | | | | | | | | | | | | | | | CAVIUM_OCTEON_SOC most place we used to use CPU_CAVIUM_OCTEON. This allows us to CPU_CAVIUM_OCTEON in places where we have no OCTEON SOC. Remove CAVIUM_OCTEON_SIMULATOR as it doesn't really do anything, we can get the same configuration with CAVIUM_OCTEON_SOC.

The clock is needed by spi driver to calculate bit rate divisor. The spi node in the current device trees either does not have the clock or is defined as dummy clock, in which case the driver probe will fail or spi will run at a wrong bit rate. - Two imx6q clock fixes, which correct axi_sels and ldb_di_sels. * tag 'imx-fixes-3.10-2' of git://git.linaro.org/people/shawnguo/linux-2.6: ARM: imx: clk-imx6q: AXI clock select index is incorrect ARM: dts: imx: fix clocks for cspi ARM i.MX6q: fix for ldb_di_sels Signed-off-by: Olof Johansson <olof@lixom.net>
