Where's C0 count/.compare IRQ is unmasked??

[Sergei Shtylyov <sshtylyov@xxxxxxxxxxxxx>]

Hello.

   I'm dazed and confused -- please forget my ignorance but I fail to see 
where the count/compare interrupt is enabled by the most platforms but Alchemy 
(which does it in arch_init_irq() -- which is causing me trouble). I'd 
expected this to happev in cevr-r4k.c but no, it doesn't (unlike cevt-sb1250.c 
for example). I'd expected this to happen in the platform code but most 
platforms disable (or ignore) this IRQ in arch_init_irq() and ignore it in 
plat_time_init() (probably correctly)? Could anyone shed some light on this? 
Where is a proper place to do it?

WBR, Sergei
