The attached patch makes byte and word writes to PCI config space work. The problem was that the pointer to the appropriate chunk of the config port needs to be juggled to allow for the fact that FRV is big endian in this case. Signed-Off-By:

The attached patch makes cache flushing work correctly on DMA consistent memory for the frv arch. On the FRV unmapped memory can't be flushed directly, but has to be kmapped first since the flush instructions take virtual pointers not physical ones. It also splits the MMU and !MMU versions into separate files. Signed-Off-By:

People love to do comparisons with highmem_start_page. However, where CONFIG_HIGHMEM=y and there is no actual highmem, there's no real page at *highmem_start_page. That's usually not a problem, but CONFIG_NONLINEAR is a bit more strict and catches the bogus address tranlations. There are about a gillion different ways to find out of a 'struct page' is highmem or not. Why not just check page_flags? Just use PageHighMem() wherever there used to be a highmem_start_page comparison. Then, kill off highmem_start_page. This removes more code than it adds, and gets rid of some nasty #ifdefs in .c files. Signed-off-by:

The attached patch makes the FR-V arch put all its memory in the DMA zone rather than the Normal zone since all the memory is available as a DMA target. Signed-Off-By:

The attached patch fixes a number of problems in the VM routines: (1) Some inline funcs don't compile if CONFIG_MMU is not set. (2) swapper_pml4 needn't exist if CONFIG_MMU is not set. (3) __free_pages_ok() doesn't counter set_page_refs() different behaviour if CONFIG_MMU is not set. (4) swsusp.c invokes TLB flushing functions without including the header file that declares them. CONFIG_SHMEM semantics: - If MMU: Always enabled if !EMBEDDED - If MMU && EMBEDDED: configurable - If !MMU: disabled Signed-Off-By: -

The attached patch marks a variable as __initdata in a header file so that the FRV gcc generates the correct access method as initdata variables are too far from the GPREL pointer to access directly. Signed-Off-By:

The attached patch makes it possible to support gp-rel addressing for small variables. Since the FR-V cpu's have fixed-length instructions and plenty of general-purpose registers, one register is nominated as a base for the small data area. This makes it possible to use single-insn accesses to access global and static variables instead of having to use multiple instructions. This, however, causes problems with small variables used to pinpoint the beginning and end of sections. The compiler assumes it can use gp-rel addressing for these, but the linker then complains because the displacement is out of range. By declaring certain variables as arrays or by forcing them into named sections, the compiler is persuaded to access them as if they can be outside the displacement range. Declaring the variables as "const void" type also works. Signed-Off-By:

The attached patch provides an out-of-line implementation of find_next_bit() and rearranges linux/bitops.h to avoid a dependency loop between inline functions in there and in asm/bitops.h trying to include one another. Signed-Off-By:

More tidying up. The htab_data structure contained 5 fields or which two were completely unused and one other was just kept for printing at boot time. I have mode the remaining two into global variables. Built and booted on iSeries (which is always lpar) and on pSeries without partitioning. Signed-off-by:

This patch is just more clean up in the ppc64 arch. It uses c99 initializers for various iSeries structures that are used to pass information to the hypervisor. Also itLpNaca is not used by any code that could be in a module, so don't export it. Built and booted. Signed-off-by:

The only place that was using the paca pointer that was in the naca was some assembler that used it to find a parameter to pass to some C code. That C code did not even declare that parameter! Remove the paca pointer. Signed-off-by:

This patch consolidates the variables that define the PPC64 cache sizes into a single structure (the were in the naca and the systemcfg structures). Those that were in the systemcfg structure are left there just because they are exported to user mode through /proc. Signed-off-by:

This patch is from Milton Miller <miltonm@bga.com>. When the update_process_times call was moved out of do_timer for the UP case, the replicator didn't track down the hiding and just added ifndef SMP. This removes the ifdefs and the indirection of calling another file for one function in a third file. Signed-off-by:
