alpha: irq: remove deprecated use of IRQF_DISABLED

2013-04-07T19:59:30Z

Interrupt handlers are always invoked with interrupts disabled, so remove all uses of the deprecated IRQF_DISABLED flag. Cc: Richard Henderson Cc: Ivan Kokshaysky Reviewed-by: Matt Turner Signed-off-by: Will Deacon Signed-off-by: Michael Cree Signed-off-by: Linus Torvalds

alpha: irq: run all handlers with interrupts disabled

2013-04-07T19:59:30Z

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() trace: __local_bh_enable+0xb8/0xd0 irq_enter+0x74/0xa0 scheduler_ipi+0x50/0x100 handle_ipi+0x84/0x260 do_entint+0x1ac/0x2e0 irq_exit+0x60/0xa0 handle_irq+0x98/0x100 do_entint+0x2c8/0x2e0 ret_from_sys_call+0x0/0x10 load_balance+0x3e4/0x870 cpu_idle+0x24/0x80 rcu_eqs_enter_common.isra.38+0x0/0x120 cpu_idle+0x40/0x80 rest_init+0xc0/0xe0 _stext+0x1c/0x20 A similar dump occurs if you try to reboot using magic-sysrq.

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

2013-04-07T19:59:30Z

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.

Select VIRT_TO_BUS directly where needed

2013-03-12T18:16:40Z

In commit 887cbce0adea ("arch Kconfig: centralise ARCH_NO_VIRT_TO_BUS") I introduced the config sybmol HAVE_VIRT_TO_BUS and selected that where needed. I am not sure what I was thinking. Instead, just directly select VIRT_TO_BUS where it is needed. Signed-off-by: Stephen Rothwell Signed-off-by: Linus Torvalds

alpha: boot: fix build breakage introduced by system.h disintegration

2013-03-08T23:05:34Z

Commit ec2212088c42 ("Disintegrate asm/system.h for Alpha") removed the system.h include from boot/head.S, which puts the PAL_* asm constants out of scope. Include so we can get building again.
