Current code had the acking disabled because just acking the interrupt disables it on some interrupt controllers (like the VIC used on Nomadik). However, not acking at all is incorrect because interrupt controllers like the GIC need an EOI indication, which is done in the ack routine. Solve this by maskacking and unmasking it appropriately, similar to how handle_level_irq operates.

However, each of these blocks have a varying number of banks, each of which have 32 GPIOs and an interrupt line. The current nomadik-gpio driver implementation can handle each of these sub-banks easily with one instance each, but cannot as-is be hooked up to them because it is an AMBA driver and it expects to see a peripheral with the appropriate peripheral ids but having only one bank and only one interrupt. Solve this by converting the driver to a platform driver.

This data is then copied to a local static variable in the core code. Since the data is copied, the original data can be marked as __initdata and discarded after startup is complete. This adds the __initdata tag to all the appropriate data in the various ep93xx board init's. Specifically, all the struct ep93xx_eth_data, struct ep93xxfb_mach_info, and struct i2c_gpio_platform_data. Also, document the various registration functions and note what data should be marked as __initdata. While here, also cleanup a couple over zealous whitespace tabs.

Currently, the kernel is hardcoded to assume the J3 position, and the serial port is always being used in polling mode. The patch adds the IRQ autodetection flag for the serial port interrupt, and also marks it as shared (as the driver for the second UHCI controller will request the interrupt in any case). Now, when the jumper is set to the J4 position, the serial port will have an interrupt line, resulting in less CPU overhead and faster throughput.

However, these platforms have a 32-bit counter which is clocked at a slower rate. The result is that the preprocessor conditions are never triggered: TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than 0x10000.

This patch adds support for a shared irq layer, which registers hardware irqs by itself and exposes virtual irq numbers to peripherals.

The change from SSCR0_SerClkDiv(2) to SSCR0_SCR(2), will make the result a little bit different in pxa2xx_spi_probe(), however, since that's only used as a default initialization value, it's acceptable.

This has the disadvantage of tying the Kernel down to a particular board as far as profiling is concerned. This patch replaces the compile-time IRQ registration with a runtime mechanism which allows the IRQs to be registered with the framework as a platform_device. A further advantage of this change is that there is scope for registering different types of performance counters in the future by changing the id of the platform_device and attaching different resources to it.

The char *name field of this struct can be used to identify the PMU, but this is cumbersome if used outside of perf. This patch replaces the name string for a PMU with an enum, which holds a unique ID for the PMU being represented. This ID can be used to index an array of names within perf, so no functionality is lost. The presence of the ID field, allows other kernel subsystems [currently oprofile] to use their own mappings for the PMU name.

This creates the following problems: 1.) Duplicate PMU accessor code. Inevitable code drift may lead to bugs in one framework that are fixed in the other. 2.) Locking issues. OProfile doesn't reprogram hardware counters between profiling runs if the events to be monitored have not been changed. This means that other profiling frameworks cannot use the counters if OProfile is in use. 3.) Due to differences in the two frameworks, it may not be possible to compare the results obtained by OProfile with those obtained by perf. This patch removes the OProfile PMU driver code and replaces it with calls to perf, therefore solving the issues mentioned above. The only userspace-visible change is the lack of SCU counter support for 11MPCore. This is currently unsupported by OProfile userspace tools anyway and therefore shouldn't cause any problems.
