From 4c35630ccda56ed494f6102d2e147fefe14b78d2 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Tue, 8 May 2007 14:46:36 -0500 Subject: [POWERPC] Change rheap functions to use ulongs instead of pointers The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().
