| * | | | cpumask: centralize cpu_online_map and cpu_possible_mapRusty Russell2008-12-13
| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup Each SMP arch defines these themselves. Move them to a central location. Twists: 1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a CONFIG_INIT_ALL_POSSIBLE for this rather than break them. 2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'. Those archs simply have phys_cpu_present_map replaced everywhere. 3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky so I just manipulate them both in sync. 4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map' declarations.

| * | | [S390] arch_setup_additional_pages argumentsMartin Schwidefsky2008-12-25
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch_setup_additional_pages currently gets two arguments, the binary format descripton and an indication if the process uses an executable stack or not. The second argument is not used by anybody, it could be removed without replacement. What actually does make sense is to pass an indication if the process uses the elf interpreter or not. The glibc code will not use anything from the vdso if the process does not use the dynamic linker, so for statically linked binaries the architecture backend can choose not to map the vdso.

* | | sh: Kill off cf-enabler with extreme prejudice.Paul Mundt2008-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the rest of the boards that were using cf-enabler "generically" have switched to setting up their mappings on their own, only the mach-se boards were left using it. All of the cf-enabler using mach-se boards use a special initialization of the MRSHPC windows rather than going through the special PTE as other SH-4 platforms do. This consolidates the MRSHPC setup logic, hooks it up on the boards that care, and gets rid of any and all remaining references to cf-enabler. This has been long overdue, as cf-enabler has been the bane of arch/sh/kernel for the last 7 years. Good riddance. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the reworked kgdb support, we always detach and reinitialize the stub. This was mostly a feature for handoffs between sh-ipl+g and the kgdb stub, but virtually no sh-ipl+g versions ever had this working right in the first place. Given that the sh-ipl+g stubs in general use today don't even support the GDB stub, and we have already killed off the special casing in the sh-sci serial driver, kill off this now unused symbol too.
