Subject: arm interrupt handling 

Hi
When I study the interrupt handling code in 2.6.39 for omap soc, found don't clear CPSR.I to enable irq till each ISR finished.
Is this true? Or I miss something, since this will be wired that the core will not service any other irq before complete before irq handling.

Best wishes
Qipeng

That might seem so from a openwrt perspective, where you custom cook the 
whole userland thing per-device, but it ain't so from a generic rootfs 
perspective.

Why should Ubuntu, Fedora etc stink up their OSes with Panda-specific 
workarounds?  And Panda is not the only device with this issue.
