Re: [PATCH 5/7] pci: Export the pci_restore_msi_state() function

quoted

I don't know why you keep talking about powerpc laptops here ... 

Well, there are Apple laptops, right?  Aren't those the "powermac" 
platform?  Now, I don't know if they support MSI, but if they do,
I get the impression that they might not restore msi state correctly,
after being put into hardware suspend.  But perhaps I'm mistaken;
I was simply grepping for various msi-related functions in various
arch subdirectories, comparing x86 to other arches, and noticed 
that code that would restore msi state seems to be missing for
most arches and most powerpc platforms.

Ah ok, i see. Well, platforms that use write_msi_msg() shouldn't need
anything special right ? So only pSeries is an issue here....

PowerBooks don't indeed have MSI support, though G5's do and some people
have been toying around with suspend/resume on them (hibernation only at
that stage) but it doesn't matter at this stage. We are specifically
talking about pSeries which is the "special" case here.

Ben.
