Tomi Valkeinen reports:
Running with latest linux-omap kernel on OMAP3 SDP board, I have
problem with iounmap(). It looks like iounmap() does not properly
free large areas. Below is a test which fails for me in 6-7 loops.
for (i = 0; i < 200; ++i) {
vaddr = ioremap(paddr, size);
if (!vaddr) {
printk("couldn't ioremap\n");
break;
}
iounmap(vaddr);
}
The changes to vmalloc.c weren't reflected in the ARM ioremap
implementation. Turns out the fix is rather simple.
