The wbsd hardware is so incredibly brain damaged that it has an internal list of commands that result in data transfers. The result being that commands that aren't on this list aren't supported. Instead of locking up, waiting for a data interrupt that will never come, we try to fail a bit more gracefully. Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

Many controllers have an upper limit on the number of blocks that can be transferred in one request. Allow the host drivers to specify this and make sure we avoid hitting this limit. Also change the max_sectors field to avoid confusion. This makes it map less directly to the block layer limits, but as they didn't apply directly on MMC cards anyway, this isn't a great loss.

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

Some MMC hosts can only handle log2 block sizes. Unfortunately, the MMC password support needs to be able to send non-log2 block sizes. Provide a capability so that the MMC password support can decide whether it should use this support or not. The unfortunate side effect of this host limitation is that any MMC card protected by a password which is not a log2 block size can not be accessed on a host which only allows a log2 block size. This change just adds the flag. The MMC password support code needs updating to use it (if and when it is finally submitted.) Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Add a capability flag for drivers to set when they can perform multi- block transfers to cards _and_ correctly report the number of bytes transferred should an error occur. The last point is very important - if a driver reports more bytes than were actually accepted by the card and an error occurs, there is the possibility for data loss.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.
