Subject: [BOOTMEM] bad physical address convertions.
Date: Tue, 05 Apr 2005 09:39:14 +0200	[thread overview]
Message-ID: <425240A2.6020504@innova-card.com> (raw)

Hi,

I'm porting linux on an embedded system based on MIPS proc. I've 
encountered several
problems and one of these is related to the physical memory which 
doesn't start to 0.
This is actually not a big issue if code that makes physical address 
convertions uses the
appropriate macros that do the job.
Unfortunately there are some places in linux where this is not the case.
"bootmem.c" is one of these places. For instance, it does "addr >> 
PAGE_SHIFT"
instead of using "phys_to_pfn" macro in order to convert a physical 
address into a page
frame number.

Are there any interests for a patch which will fix that ?

Regards,

          Franck.
