Shared registers +------------------- +Some SoC devices share registers between them. ie. the i2c devices use +a single clock control register, and almost all device are affected by +the port_config register. Devices which need to manipulate shared regs +should look to the parent SoC node. The soc node is responsible +for arbitrating all shared register access. diff --git a/MAINTAINERS b/MAINTAINERS index f85c603b02a3..93a338daedd8 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -2523,6 +2523,12 @@ M: olof@lixom.net L: netdev@vger.kernel.org S: Maintained +PA SEMI SMBUS DRIVER +P: Olof Johansson +M: olof@lixom.net +L: i2c@lm-sensors.org +S: Maintained + PARALLEL PORT SUPPORT P: Phil Blundell M: philb@gnu.org diff --git a/arch/mips/Kconfig b/arch/mips/Kconfig index 5fe195a41a80..a92ce6bd7cf1 100644 --- a/arch/mips/Kconfig +++ b/arch/mips/Kconfig @@ -598,8 +598,6 @@ config SGI_IP32 select ARC select ARC32 select BOOT_ELF32 - select OWN_DMA - select DMA_IP32 select DMA_NONCOHERENT select HW_HAS_PCI select R5000_CPU_SCACHE @@ -883,9 +881,6 @@ config DMA_NONCOHERENT config DMA_NEED_PCI_MAP_STATE bool -config OWN_DMA - bool - config EARLY_PRINTK bool diff --git a/arch/mips/configs/ip27_defconfig b/arch/mips/configs/ip27_defconfig index 96090f28373b..f21186c12d81 100644 --- a/arch/mips/configs/ip27_defconfig +++ b/arch/mips/configs/ip27_defconfig @@ -264,7 +264,7 @@ CONFIG_BINFMT_ELF=y CONFIG_MIPS32_COMPAT=y CONFIG_COMPAT=y CONFIG_MIPS32_O32=y -# CONFIG_MIPS32_N32 is not set +CONFIG_MIPS32_N32=y CONFIG_BINFMT_ELF32=y # diff --git a/arch/mips/dec/int-handler.S b/arch/mips/dec/int-handler.S index b251ef864c33..00cecdcc75f2 100644 --- a/arch/mips/dec/int-handler.S +++ b/arch/mips/dec/int-handler.S @@ -264,9 +264,6 @@ srlv t3,t1,t2 handle_it: - LONG_L s0, TI_REGS($28) - LONG_S sp, TI_REGS($28) - PTR_LA ra, ret_from_irq j dec_irq_dispatch nop @@ -277,7 +274,6 @@ fpu: #endif spurious: - PTR_LA ra, _ret_from_irq j spurious_interrupt nop END(plat_irq_dispatch) diff --git a/arch/mips/kernel/entry.S b/arch/mips/kernel/entry.S index f10b6a19f8bf..0b78fcbf044a 100644 --- a/arch/mips/kernel/entry.S +++ b/arch/mips/kernel/entry.S @@ -21,24 +21,21 @@ #endif #ifndef CONFIG_PREEMPT - .macro preempt_stop - local_irq_disable - .endm #define resume_kernel restore_all +#else +#define __ret_from_irq ret_from_exception #endif .text .align 5 -FEXPORT(ret_from_irq) - LONG_S s0, TI_REGS($28) -#ifdef CONFIG_PREEMPT -FEXPORT(ret_from_exception) -#else - b _ret_from_irq +#ifndef CONFIG_PREEMPT FEXPORT(ret_from_exception) - preempt_stop + local_irq_disable # preempt stop + b __ret_from_irq #endif -FEXPORT(_ret_from_irq) +FEXPORT(ret_from_irq) + LONG_S s0, TI_REGS($28) +FEXPORT(__ret_from_irq) LONG_L t0, PT_STATUS(sp) # returning to kernel mode? andi t0, t0, KU_USER beqz t0, resume_kernel diff --git a/arch/mips/kernel/linux32.c b/arch/mips/kernel/linux32.c index ca7ad78f4def..fc4dd6c9dd80 100644 --- a/arch/mips/kernel/linux32.c +++ b/arch/mips/kernel/linux32.c @@ -39,6 +39,7 @@ #include <net/sock.h> #include <net/scm.h> +#include <asm/compat-signal.h> #include <asm/ipc.h> #include <asm/sim.h> #include <asm/uaccess.h> @@ -736,3 +737,49 @@ _sys32_clone(nabi_no_regargs struct pt_regs regs) return do_fork(clone_flags, newsp, ®s, 0, parent_tidptr, child_tidptr); } + +/* + * Implement the event wait interface for the eventpoll file.
