* [MIPS] Compile __do_IRQ() when really neededFranck Bui-Huu2006-12-06
| | | | | | | | | | | | | | | | | __do_IRQ() is needed only by irq handlers that can't use default handlers defined in kernel/irq/chip.c. For others platforms there's no need to compile this function since it won't be used. For those platforms this patch defines GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for this purpose. Futhermore for platforms which do not use __do_IRQ(), end() method which is part of the 'irq_chip' structure is not used. This patch simply removes this method in this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | N32 SysV IPC system calls should use 32-bit compatible code. arch/mips/kernel/linux32.c have similar compatible code for O32, but ipc/compat.c seems more complete. We can use it for both N32 and O32.

| * [POWERPC] pSeries/kexec: Fix for interrupt distributionMohan Kumar M2006-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows any secondary CPU thread also to become boot cpu for POWER5. The patch is required to solve kdump boot issue when the kdump kernel is booted with parameter "maxcpus=1". XICS init code tries to match the current boot cpu id with "reg" property in each CPU node in the device tree. But CPU node is created only for primary thread CPU ids and "reg" property only reflects primary CPU ids. So when a kernel is booted on a secondary cpu thread above condition will never meet and the default distribution server is left as zero. This leads to route the interrupts to CPU 0, but which is not online at this time. We use ibm,ppc-interrupt-server#s to check for both primary and secondary CPU ids. Accordingly default distribution server value is initialized from "ibm,ppc-interrupt-gserver#s" property. We loop through ibm,ppc-interrupt-gserver#s property to find the global distribution server from the last entry that matches with boot cpuid.

| | | | | | | | | | | | | | | | | | | | | | It's currently not possible to build the default zImage target if PS3 is the only selected platform. This is a hack to fall back to building the pseries style zImage, so the build is successful. This will probably change in the future, if someone writes a PS3 specific boot wrapper.

| * [POWERPC] ps3: multiplatform build fixesArnd Bergmann2006-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few code paths need to check whether or not they are running on the PS3's LV1 hypervisor before making hcalls. This introduces a new firmware feature bit for this, FW_FEATURE_PS3_LV1. Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES, FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time, which is a bug. The same problem can also happen for (PPC_ISERIES && !PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I introduce a new CONFIG_PPC_NATIVE option that is set when at least one platform is selected that can run without a hypervisor and then turns the firmware feature check into a run-time option. The new cell oprofile support that was recently merged does not work on hypervisor based platforms like the PS3, therefore make it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change if we get oprofile support for PS3. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
