* [PATCH] spufs: Turn off debugging outputArnd Bergmann2006-01-092-2/+3
| | | | | | | | spufs is rather noisy when debugging is enabled, this turns off the messages for production use. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] spufs: Fix oops when spufs module is not loadedArnd Bergmann2006-01-091-4/+6
| | | | | | | | | try_module_get returns true when NULL arguments, so we first need to check if there is a module loaded before getting the reference count. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] spufs: fix local store page refcountingArnd Bergmann2006-01-092-2/+3
| | | | | | | | | | | With the new rules for reserved pages, the spufs now needs working page reference counting. I should probably look into converting to vm_insert_page, but for now this patch makes spufs work again.

* [PATCH] powerpc: Add support for "linux,usable-memory" on memory nodesMichael Ellerman2006-01-092-3/+13
| | | | | | | | | | | | | Milton has proposed that we should support a "linux,usable-memory" property on memory nodes which describes, in preference to "reg", the regions of memory Linux should use. This facility is required for kdump to inform the second kernel which memory it should use.

* [PATCH] powerpc: Add arch dependent basic infrastructure for Kdump.Michael Ellerman2006-01-0912-9/+345
| | | | | | | | | | | | | | | | | | | | Implementing the machine_crash_shutdown which will be called by crash_kexec (called in case of a panic, sysrq etc.). Disable the interrupts, shootdown cpus using debugger IPI and collect regs for all CPUs. elfcorehdr= specifies the location of elf core header stored by the crashed kernel. This command line option will be passed by the kexec-tools to capture kernel. savemaxmem= specifies the actual memory size that the first kernel has and this value will be used for dumping in the capture kernel.

* [PATCH] powerpc: Fixups for kernel linked at 32 MBMichael Ellerman2006-01-094-17/+37
| | | | | | | | | | | | | | | | | | | | | | There's a few places where we need to fix things up for the kernel to work if it's linked at 32MB: - platforms/powermac/smp.c To start secondary cpus on pmac we patch the reset vector, which is fine. Except if we're above 32MB we don't have enough bits for an absolute branch, it needs to relative. - kernel/head_64.s - A few branches in the cpu hold code need to load the full target address and do a bctr. - after_prom_start needs to load PHYSICAL_START as the dest address, not 0. - The exception prolog needs to load the low word of the target adddress, not just the low halfword. - Fixup handling of the initial stab address. - kernel/setup_64.c smp_release_cpus() needs to write 1 to the spinloop flag near 0, not 32 MB.

* [PATCH] powerpc: Reroute interrupts from 0 + offset to PHYSICAL_START + offsetMichael Ellerman2006-01-095-1/+77
| | | | | | | | | | | | Regardless of where the kernel's linked we always get interrupts at low addresses. This patch creates a trampoline in the first 3 pages of memory, where interrupts land, and patches those addresses to jump into the real kernel code at PHYSICAL_START. We also need to reserve the trampoline code and a bit more in prom.c Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: Create a trampoline for the fwnmi vectorsMichael Ellerman2006-01-094-12/+20
| | | | | | | | | The fwnmi vectors can be anywhere < 32 MB, so we need to use a trampoline for them. The kdump kernel will register the trampoline addresses, which will then jump up to the real code above 32 MB.

* [PATCH] powerpc: Separate usage of KERNELBASE and PAGE_OFFSETMichael Ellerman2006-01-099-24/+37
| | | | | | | | | | | | | | | | | | | | | This patch separates usage of KERNELBASE and PAGE_OFFSET. I haven't looked at any of the PPC32 code, if we ever want to support Kdump on PPC we'll have to do another audit, ditto for iSeries. This patch makes PAGE_OFFSET the constant, it'll always be 0xC * 1 gazillion for 64-bit. To get a physical address from a virtual one you subtract PAGE_OFFSET, _not_ KERNELBASE. KERNELBASE is the virtual address of the start of the kernel, it's often the same as PAGE_OFFSET, but _might not be_. If you want to know something's offset from the start of the kernel you should subtract KERNELBASE.

* [PATCH] powerpc: Add a is_kernel_addr() macroMichael Ellerman2006-01-099-15/+20
| | | | | | | | | | | There's a bunch of code that compares an address with KERNELBASE to see if it's a "kernel address", ie. >= KERNELBASE. The proper test is actually to compare with PAGE_OFFSET, since we're going to change KERNELBASE soon. So replace all of them with an is_kernel_addr() macro that does that.

* [PATCH] ppc32: m8xx watchdog updateMarcelo Tosatti2006-01-094-34/+90
| | | | | | | | | | | | | | | | | | | | | | | This updates m8xx_wdt as follows: 1) Remove now obsolete fpos check in the write() function. The driver is currently non functional due to this bug. 2) Use in/out macros for register access. 3) Allows m8xx_wdt to use a kernel timer instead of the builtin RTC/PIT for keep-alive trigger (which is responsible for servicing the watchdog until an userspace application takes over). For instance Cyclades PRxK boards (MPC 855T based) have a non-functional internal RTC/PIT unit. Behaviour for boards with RTC/PIT is unchaged. 4) The last change required moving the RTCSC register setting code to a weak function which can be overriden by board specific files. Otherwise the timer init code trashes the register making it impossible for m8xx_wdt to detect the situation.
