[PATCH] FRV: Permit large kmalloc allocations

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: David Howells <[email protected]>

Permit kmalloc() to make allocations of up to 32MB if so configured.  This may
be useful under NOMMU conditions where vmalloc() can't do this.
