Some hosts (that is, FSL eSDHC) throw PIO interrupts during DMA transfers, this causes tons of unneeded interrupts, and thus highly degraded speed. This patch modifies the driver so that now we only enable relevant (DMA or PIO) interrupts during transfers.

Card detection interrupts should be handled separately as they should not be enabled before mmc_add_host() returns and should be disabled before calling mmc_remove_host(). The same is for suspend and resume routines. sdhci_init() no longer enables card-detection irqs. Instead, two new functions implemented: sdhci_enable_card_detection() and sdhci_disable_card_detection(). New sdhci_reinit() call implemented to behave the same way as the old sdhci_init(). Also, this patch implements and uses few new helpers to manage IRQs in a more conveinient way, that is: - sdhci_clear_set_irqs() - sdhci_unmask_irqs() - sdhci_mask_irqs() - SDHCI_INT_ALL_MASK constant sdhci_enable_sdio_irq() converted to these new helpers, plus the helpers will be used by the subsequent patches.

Currently the SDHCI driver works with PCI accessors (write{l,b,w} and read{l,b,w}). With this patch drivers may change memory accessors, so that we can support hosts with "weird" IO memory access requirments. For example, in "FSL eSDHC" SDHCI hardware all registers are 32 bit width, with big-endian addressing. That is, readb(0x2f) should turn into readb(0x2c), and readw(0x2c) should be translated to le16_to_cpu(readw(0x2e)).

Some MMC commands result in the card becoming busy after the response is received. This needs to be specified for the omap_hsmmc host controller, which is what this patch does. However, the effect is that some commands with no data will cause a Transfer Complete (TC) interrupt in addition to the Command Complete (CC) interrupt. In order to deal with that, the irq handler has needed a few changes also. The benefit of this change is that the omap_hsmmc host controller driver now waits for the TC interrupt while the card is busy, so the mmc_block driver needs to poll the card status just once instead of repeatedly. i.e. the net result is more sleep and less cpu. The command sequence for open-ended multi-block write with DMA is now: Issue write command CMD25 Receive CC interrupt Data is sent Receive TC interrupt (DMA is done) Issue stop command CMD12 Receive CC interrupt Card is busy Receive TC interrupt Card is now ready for next transfer Signed-off-by: NAdrian Hunter <adrian.hunter@nokia.com> Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

Remove code that turns MMC1 power back on after it has been powered off (when the voltage is 1.8V). The offending code is not necessary because the host controller bus voltage is initialized to 3V when probing or resuming. Note that MMC powers up with the highest voltage available (see mmc_power_up()) which will be 3V also.

Currently we are using an explicit udev rule to trigger loading of the mmc-block module when an MMC or SD card is detected: SUBSYSTEM=="mmc", RUN+="/sbin/modprobe -Qba mmc-block" It makes much more sense for the mmc bus driver and the mmc-block module to share MODALIAS information so that they are linked automatically. There is no real information of use in the MMC system at the current time. All devices inserted require us to load the mmc-block device. Until such time as useful parameters exist simply reflect the module linkage via the module alias below: mmc:block Signed-off-by: NAndy Whitcroft <apw@canonical.com> Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections.

This patch fixes bug #12208: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12208 Subject : uml is very slow on 2.6.28 host This turned out to be not a scheduler regression, but an already existing problem in ptrace being triggered by subtle scheduler changes. The problem is this: - task A is ptracing task B - task B stops on a trace event - task A is woken up and preempts task B - task A calls ptrace on task B, which does ptrace_check_attach() - this calls wait_task_inactive(), which sees that task B is still on the runq - task A goes to sleep for a jiffy - ... Since UML does lots of the above sequences, those jiffies quickly add up to make it slow as hell. This patch solves this by not rescheduling in read_unlock() after ptrace_stop() has woken up the tracer. Thanks to Oleg Nesterov and Ingo Molnar for the feedback.
