| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Renamed the MPC8568 MDS platform code to follow other 85xx boards. There isn't anything specific about the 8568 MDS code that wouldn't apply to another 85xx MDS system at this point. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactored and cleaned up ucc_fast.c and ucc_slow.c so that the two files look more alike and are easier to read. Removed uccf_printk() and related functions, because they were just front-ends to printk(). Fixed some spacing and tabbing issues. Minor optimizations of some code. Changed the type of some variables to their proper type (mostly buffer descriptors). Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC836x PB board is really just one part of the MPC836x MDS. We currently name all other PB boards as MDS. Removed all references to PB and replaced with MDS. Additionally renamed the .dts to match the defconfig (mpc836x_mds*). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | * | | [POWERPC] pseries: Enabling auto poweron after power is restored.Manish Ahuja2007-02-174-2/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During power outages, the UPS notifies the system for a shutdown. In the current setup, it isn't possible to poweron when power is restored. This patch fixes the issue by calling the right ibm,power-off-ups token during such events. It also adds a sysfs interface so userspace can specify whether or not to power on when power is restored.

| | | | | | | | | | | | The code for bolting hash entries for ioremap done before proper mm initialization has a grown a bug when using 64K pages on a machine where non-cacheable mappings are demoted to 4K HW pages. The wrong page size index is being passed to the hash table mapping functions causing a crash at boot on some pSeries machines using bare metal linux. This fixes it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After updating several machines to 2.6.20, I can't boot anymore the single one of them that supports the NX bit and is configured as a 32-bit system. My understanding is that the VDSO changes in 2.6.20-rc7 were not fully cooked, in that with that config option enabled VDSO_SYM(x) now equals x, meaning that an address in the fixmap area is now being passed to apps via AT_SYSINFO. However, the page is mapped with PAGE_READONLY rather than PAGE_READONLY_EXEC. I'm not certain whether having app code go through the fixmap area is intended, but in case it is here is the simple patch that makes things work again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I implemented the DECLARE_PER_CPU(var) macros, I was careful that people couldn't use "var" in a non-percpu context, by prepending percpu__. I never considered that this would allow them to overload the same name for a per-cpu and a non-percpu variable.

This was always a vain hope; start_kernel won't get far without setup. It's also impossible for paravirt_ops backends which don't sit in the arch/i386/kernel directory: they can't link before paravirt.o anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old Cyrix 5520 CPU detection code relied upon the PCI layer setup being done earlier than the CPU setup, which is no longer true. Fortunately we know that if the processor is a MediaGX we can do type 1 pci config accesses to check the companion chip. We thus do those directly and from this find the 5520 and implement the workarounds for the timer problem Original report from takada@mbf.nifty.com, I sent a proposed patch which Takara then corrected, tested and sent back to the list on 10th January.
