By default, non-privileged tasks can only mlock() a small amount of
memory to avoid a DoS attack by ordinary users. The Linux kernel
defaulted to 32k (on a 4k page size system) to accommodate the needs of
gpg.
However, newer gpg2 needs 64k in various circumstances and otherwise
fails miserably, see bnc#329675.
Change the default to 64k, and make it more agnostic to PAGE_SIZE.

Every call of kvm_set_irq() should offer an irq_source_id, which is
allocated by kvm_request_irq_source_id(). Based on irq_source_id, we
identify the irq source and implement logical OR for shared level
interrupts.
The allocated irq_source_id can be freed by kvm_free_irq_source_id().
Currently, we support at most sizeof(unsigned long) different irq sources.
[Amit: - rebase to kvm.git HEAD
- move definition of KVM_USERSPACE_IRQ_SOURCE_ID to common file
- move kvm_request_irq_source_id to the update_irq ioctl]
[Xiantao: - Add kvm/ia64 stuff and make it work for kvm/ia64 guests]

Right now callers have to check whether scsi_host->bqt is already
set up, it's much cleaner to just have scsi_init_shared_tag_map()
does this check on its own.

Impact: build fix
DIE_OOPS is now used in the generic trace handling code so it needs to
be defined for all architectures. Define it in asm-generic so that it's
available to all by default and doesn't cause build errors for
architectures that rely on the generic implementation.

libata currently has a pretty dumb ATA_MAX_QUEUE loop for finding
a free tag to use. Instead of fixing that up, convert libata to
using block layer tagging - gets rid of code in libata, and is also
much faster.
