2006-03-22[PATCH] remove set_page_count() outside mm/Nick Piggin
set_page_count usage outside mm/ is limited to setting the refcount to 1. Remove set_page_count from outside mm/, and replace those users with init_page_count() and set_page_refcounted(). This allows more debug checking, and tighter control on how code is allowed to play around with page->_count.

2006-01-09[PATCH] powerpc: Unify udbg (#2)Benjamin Herrenschmidt
This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

2005-11-10powerpc: Move some extern declarations from C code into headersPaul Mackerras
This also make klimit have the same type on 32-bit as on 64-bit, namely unsigned long, and defines and initializes it in one place. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-27[PATCH] powerpc: Purge bootinfo.hDavid Gibson
With ARCH=powerpc we assume the presence of a device tree, so we don't require any support for the old bi_recs method of passing boot parameters. Likewise, we've never needed it for ppc64, but we still had an include/asm-ppc64/bootinfo.h from which nothing was used. This patch removes that file, and all references to it in arch/ppc64 and arch/powerpc. A related, unused variable 'boot_mem_size' is also removed from setup_32.c. The bootinfo stuff remains in ARCH=ppc for the time being. Built and booted on Power5 (ARCH=ppc64 and ARCH=powerpc), built for 32-bit powermac (ARCH=powerpc and ARCH=ppc).

2005-10-26powerpc32: Limit memory to lowmem if !CONFIG_HIGHMEM.Paul Mackerras
This trims off the extra unusable memory from the lmb structure, so we don't try to use it. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-22powerpc: Move agp_special_page export to where it is definedPaul Mackerras
... instead of exporting it in arch/*/kernel/ppc_ksyms.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-17powerpc: Initialize btext subsystem later, after prom_initPaul Mackerras
We were initializing the btext stuff from prom_init(), thus breaking the rule that all communication between prom_init() and the rest of the kernel has to be via the flattened device tree. This removes the btext initialization calls from prom_init() and initializes it instead after the device tree is unflattened. It would be nice to do it earlier, but that needs some more infrastructure to find the properties we need in the flattened device tree. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-10powerpc: Rename files to have consistent _32/_64 suffixesPaul Mackerras
This doesn't change any code, just renames things so we consistently have foo_32.c and foo_64.c where we have separate 32- and 64-bit versions. Signed-off-by: Paul Mackerras <paulus@samba.org>
