cris: update comments for generic idle conversion

2014-06-06T23:08:18Z

As of commit 8dc7c5ecd8d0 ("cris: Use generic idle loop"), cris no longer provides cpu_idle(). - On cris-v10, etrax_gpio_wake_up_check() is called from default_idle() instead of cpu_idle(), - On cris-v32, etrax_gpio_wake_up_check() is not called from default_idle(), so remove this (copy-and-paste?) part.

sys_sgetmask/sys_ssetmask: add CONFIG_SGETMASK_SYSCALL

2014-06-04T23:54:14Z

sys_sgetmask and sys_ssetmask are obsolete system calls no longer supported in libc. This patch replaces architecture related __ARCH_WANT_SYS_SGETMAX by expert mode configuration.That option is enabled by default for those architectures.

PCI: Turn pcibios_penalize_isa_irq() into a weak function

2014-05-27T22:23:58Z

pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA is not used by some architectures. Make pcibios_penalize_isa_irq() a __weak function to simplify the code. This removes the need for new platforms to add stub implementations of pcibios_penalize_isa_irq().

arch,cris: Convert smp_mb__*()

2014-04-18T12:20:00Z

Cris fully relies on asm-generic/barrier.h, therefore its smp_mb() is barrier(), thus we can use the default implementation that uses smp_mb(). (Include asm/system.h and asm/barrier.h to avoid header dependency hell.) Signed-off-by: Peter Zijlstra Acked-by: Jesper Nilsson Acked-by: Paul E.

Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP

2014-04-07T23:36:11Z

If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König Acked-by: Arnd Bergmann Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
