2008-07-12[NET] smc91x: prepare SMC_USE_PXA_DMA to be specified in platform dataEric Miao
Now that the original SMC_USE_PXA_DMA specific code will always being built if CONFIG_ARCH_PXA is defined, so to make this part of the code to be PXA public, and still prevent it from being built if support of PXA is not selected. A SMC91X_USE_DMA flag is added to the platform data to allow platform to choose its usage of DMA. Note this flag itself is so named to be generic enough (assuming other platforms can also use DMA). It keeps backward compatibility to set the SMC91X_USE_DMA flag if SMC_USE_PXA_DMA is still defined.

2008-07-12[NET] smc91x: prepare for SMC_IO_SHIFT to be a platform configurable variableEric Miao
Now one can use the following code #define SMC_IO_SHIFT lp->io_shift to make SMC_IO_SHIFT a variable. This, however, will slightly increase the CPU overhead and have negative impact on the network performance. The tradeoff is, this can be specified in the smc91x platform data so that multiple boards support can be built in a single zImage.

2008-07-12[NET] smc91x: add SMC91X_NOWAIT flag to platform dataEric Miao
And also favors the usage of SMC91X_NOWAIT over the hardcoded SMC_NOWAIT by converting "nowait" (module parameter overridable) to platform flag. There are several possibilities: 1. platform data present - preferred and use as is 2. platform data absent - use "nowait", it can be: a. SMC_NOWAIT if defined b. default to 0 if SMC_NOWAIT isn't defined c. overriden by module parameter Signed-off-by: Eric Miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Acked-by: Jeff Garzik <jgarzik@pobox.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-07-12[NET] smc91x: remove "irq_flags" from "struct smc91x_platdata"Eric Miao
IRQ trigger type can be specified in the IRQ resource definition by IORESOURCE_IRQ_*, we need only one way to specify this. This also fixes the following small issue: To allow dynamic support for multiple platforms, when those relevant macros are not defined for one specific platform, the default case will be: - SMC_DYNAMIC_BUS_CONFIG defined - and SMC_IRQ_FLAGS = IRQF_TRIGGER_RISING While if "irq_flags" is missing when defining the smc91x_platdata, usually as follows: static struct smc91x_platdata xxxx_smc91x_data = { .flags = SMC91X_USE_XXBIT, }; The lp->cfg.irq_flags will always be overriden by the above structure (due to a memcpy), thus rendering lp->cfg.irq_flags to be "0" always. (regardless of the default SMC_IRQ_FLAGS or IORESOURCE_IRQ_* flags) Fixes this by forcing to use IORESOURCE_IRQ_* flags if present, and make the only user of smc91x_platdata.irq_flags (renesas/migor) to use IORESOURCE_IRQ_*.

2008-06-24KVM: close timer injection race window in __vcpu_runMarcelo Tosatti
If a timer fires after kvm_inject_pending_timer_irqs() but before local_irq_disable() the code will enter guest mode and only inject such timer interrupt the next time an unrelated event causes an exit. It would be simpler if the timer->pending irq conversion could be done with IRQ's disabled, so that the above problem cannot happen. For now introduce a new vcpu requests bit to cancel guest entry.
