My fault: actually, those were not all lock debugging functions. It
really prints errors when lock correctness proving is enabled. I thus
decided to just assign the callback functions directly to irq_desc
struct fields, as it is done in mach-msm.

There is, however, another error showing up: it complains about my use
of ioremap inside arch_reset(). Is it fine to just hardcode the
virtual address of the respective register and use that directly in
this case? Something along the lines of:

/* PM Software Reset request register */
#define VT8500_PMSR_VIRT	0xf8130060

static inline void arch_reset(char mode, const char *cmd)
{
	writel(1, VT8500_PMSR_VIRT);
}

Thanks,
Alexey
