This modifies drivers/ata/sata_vsc.c to only set the cache line size to 0x80 if the default value is zero. Apparently zero isn't allowed due to a bug in the chip, but I've found performance is much better with the (non-zero) default instead of 0x80.

This patch is against each libata driver. Two IRQ calls are added in ata_port_operations. - irq_on() is used to enable interrupts. - irq_ack() is used to acknowledge a device interrupt. In most drivers, ata_irq_on() and ata_irq_ack() are used for irq_on and irq_ack respectively. In some drivers (ex: ahci, sata_sil24) which cannot use them as is, ata_dummy_irq_on() and ata_dummy_irq_ack() are used.

Convert libata core layer and LLDs to use iomap. * managed iomap is used. Pointer to pcim_iomap_table() is cached at host->iomap and used through out LLDs. This basically replaces host->mmio_base. * if possible, pcim_iomap_regions() is used Most iomap operation conversions are taken from Jeff Garzik <jgarzik@pobox.com>'s iomap branch.

Update libata LLDs to use devres. Core layer is already converted to support managed LLDs. This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.

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.

The biggest change is that ata_host_set is renamed to ata_host. * ata_host_set => ata_host * ata_probe_ent->host_flags => ata_probe_ent->port_flags * ata_probe_ent->host_set_flags => ata_probe_ent->_host_flags * ata_host_stats => ata_port_stats * ata_port->host => ata_port->scsi_host * ata_port->host_set => ata_port->host * ata_port_info->host_flags => ata_port_info->flags * ata_(.*)host_set(.*)\(\) => ata_\1host\2() The leading underscore in ata_probe_ent->_host_flags is to avoid reusing ->host_flags for different purpose. Currently, the only user of the field is libata-bmdma.c and probe_ent itself is scheduled to be removed. ata_port->host is reused for different purpose but this field is used inside libata core proper and of different type.

Convert sata_sis, svw, uli and vsc drivers to new EH. All the drivers used to specify ATA_FLAG_SATA_RESET to tell libata to use SATA hardreset instead of SRST. This patch makes all the converted drivers use the standard bmdma error handler which uses both SRST and SATA hardreset. All the controllers should be able to perform SRST but still needs verification. If some of the controllers can't do SRST, it will be very easy to spot as it will show up during boot probing.

We need to pass the device in order to do per device checks such as 32bit I/O enables. With the changes to include dev->ap we now don't have to add parameters however just clean them up.

Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out. Downside is that scsi_host_alloc can't check for the total lack of EH anymore, but the transition period from old EH where we needed it is long gone already.

We want ->tf_read() to get a complete snapshot of all taskfile registers, without requiring the callers to manually call ata_chk_status() and ata_chk_err() themselves. This also fixes a minor bug in sata_vsc where the lower bits of the feature register were incorrectly placed in the HOB (high order bits) portion of struct ata_taskfile.
