alpha: irq: remove deprecated use of IRQF_DISABLED

2013-04-07T19:59:30+00:00

Interrupt handlers are always invoked with interrupts disabled, so
remove all uses of the deprecated IRQF_DISABLED flag.

alpha: irq: run all handlers with interrupts disabled

2013-04-07T19:59:30+00:00

Linux has expected that interrupt handlers are executed with local
interrupts disabled for a while now, so ensure that this is the case on
Alpha even for non-device interrupts such as IPIs.

Without this patch, secondary boot results in the following backtrace:

  warning: at kernel/softirq.c:139 __local_bh_enable+0xb8/0xd0()

A similar dump occurs if you try to reboot using magic-sysrq.

alpha: makefile: don't enforce small data model for kernel builds

2013-04-07T19:59:30+00:00

Due to all of the goodness being packed into today's kernels, the
resulting image isn't as slim as it once was.

In light of this, don't pass -msmall-data to gcc, which otherwise results
in link failures due to impossible relocations when compiling anything but
the most trivial configurations.

KVM: Allow cross page reads and writes from cached translations.

2013-04-07T10:05:35+00:00

This patch adds support for kvm_gfn_to_hva_cache_init functions for
reads and writes that will cross a page.  If the range falls within
the same memslot, then this will be a fast operation.  If the range
is split between two memslots, then the slower kvm_read_guest and
kvm_write_guest are used.

Tested: Test against kvm_clock unit tests.
