Make the zImage relocateable. So yaboot could just load and run any ELF binary, without worrying about its load address. Signed-off-by:

Compute the vmlinux size at runtime. Use Z_FULL_FLUSH instead of Z_FINISH, to extract only the ELF header and ELF program header. ->p_memsz is the required memory range for the executable, including bss ->p_filesz is the size of .text, .data and other runtime sections These values must be used for the claim call. All additional memory needed by the kernel is claimed in prom_init, remove the extra Mb. Pass the full memsize as target area to gunzip, otherwise not everything will be uncompressed. flush_cache has to flush all runtime sections, do not reduce the memrange by the ->p_offset value because its just that: an offset. Remove the Makefile code to produce an imagesize.c, its not needed anymore. Remove all FORCE flags, to not rebuild the zImage if vmlinux was not changed. Signed-off-by:

Switch ppc64 to the in-kernel zlib, it has less bugs than the current one. The code in arch/ppc64/boot is compiled as 32bit, so it can not use the includes from include/asm. Copy all zlib related header files and convert them with sed. Reduce the scratch size to 47k, check possible changes at runtime. Signed-off-by:

This patch fixes a numbers of issues regarding to that both 8xx and 82xx began to use ppc_sys model: - Platform is now identified by default deviceless SOC, if no BOARD_CHIP_NAME is specified in the bard-specific header. For the list of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and mpc82xx_sys.c for 8xx and 82xx respectively. - Fixed a bug in identification by name - if the name was not found, it returned -1 instead of default deviceless ppc_spec. - fixed devices amount in the 8xx platform system descriptions Signed-off-by:

Change the phys_mem_access_prot() function to take a pfn instead of an address. This allows mmap64() to work on /dev/mem for addresses above 4G on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no need to convert to an address; in fact, it's actively bad, since the conversion can overflow when the address is above 4G. Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an address by directly comparing to max_pfn. Working with max_pfn instead of high_memory fixes page_is_ram() to give the right answer for highmem pages. Signed-off-by:

Here is an uptodated version of the MPC8xx PCMCIA driver for v2.6, addressing comments by Jeff and Dominik: - use IO accessors instead of direct device memory referencing - avoid usage of non-standard "uint/uchar" data types - kill struct typedef's Will submit it for inclusion once v2.6.14 is out. Testing on 8xx platforms is more than welcome! Works like a charm on our custom hardware (CONFIG_PRxK). Cc: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by:

Convert core 8xx drivers to use in_xxxbe/in_xxx macros instead of direct memory references. Other than making IO accesses explicit (which is a plus for readability), a common set of macros provides a unified place for the volatile flag to constraint compiler code reordering. There are several unlucky places at the moment which lack the volatile flag. Signed-off-by:

Depending on how GCC is built, GCC 4 may generate altivec instructions without user explicitly requesting vector operations in the code. Although this is a performance booster for user applications, it is a problem for kernel. This patch explicitly instruct GCC to NOT generate altivec instructions while building the kernel. Here are some test cases I ran. (1) build gcc 4.0.1 with '--with-cpu=7450 --enable-altivec --enable-cxx-flags=-mcpu=7450', and use this gcc to build kernel WITHOUT this kernel patch. Kernel fail to boot up on a 7450 board because of altivec instructions in kernel. (2) build gcc 4.0.1 with "--with-cpu=7450 --enable-altivec --enable-cxx-flags=-mcpu=7450", and use this gcc to build kernel WITH this kernel patch. Kernel boot up on a 7450 board without any problem. (3) build gcc 4.0.1 with "--with-cpu=750 --enable-cxx-flags=-mcpu=750", and use this gcc to build kernel with or without this kernel patch. Kernel boot up on a 7450 board without any problem. This patch should also work with GCC 3 or even earlier GCC 2.95.3. Signed-off-by:Lee Nicks <allinux@gmail.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by:

The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

This patch moves the XICS interrupt controller code into the platforms/pseries directory, since it only appears on pSeries machines. If it ever appears on some other machine we can move it to sysdev, although xics.c itself will need a bunch of changes in that case to remove pSeries specific assumptions. Signed-off-by:
