The following patch speeds up the restoring of swsusp images on x86-64 and makes the assembly code more readable (tested and works on AMD64). Signed-off-by:
Rafael J. Wysocki <rjw@sisk.pl> Changed by AK to not hardcode any C values and get them from offset.h instead and not flushing CR3 needlessly (according to Pavel it was just an old debugging measure that is not needed anymore) Signed-off-by:

Andi Kleen reported a problem where a very slow boot caused the timer interrupt on a secondary CPU to go off before the CPU was actually brought up by the core code, so the CPU_PREPARE notifier hadn't been called, so the per-cpu timer code wasn't set up. This was caused by enabling interrupts around calibrate_delay() on secondary CPUs, which is not actually neccessary (interrupts on CPU 0 increments jiffies, which is all that is required). So delay enabling interrupts until the actual __cpu_up() call for that CPU. Signed-off-by:

Enable the virtual ethernet and virtual scsi drivers in the pseries config. Since our root device may be on either we need them compiled in (unless we play initrd tricks). Signed-off-by:

The kernel wouldnt link when SYSVIPC was disabled. x86-64 was already defining a cond_syscall, instead of duplicating it in the ppc64 port move it into the arch specific portion of kernel/sys_ni.c Signed-off-by:

This patch is from Nathan Lynch <nathanl@austin.ibm.com>. This changes struct device_node and associated code to use the kref api for object refcounting and freeing. I've given it some testing on pSeries with cpu add/remove and verified that the release function works. The change is somewhat cosmetic but it does make the code easier to understand... at least I think so =) The only real change is that the refcount on all device_nodes is initialized at 1, and the device node is freed when the refcount reaches 0 (of_remove_node has the extra "put" to ensure that this happens). This lets us get rid of the OF_STALE flag and macros in prom.h. Signed-off-by:

This patch is originally from Nathan Lynch <nathanl@austin.ibm.com>. Sparse gives a warning "constant ... is so big it is long" for every expression where we check bits in the cur_cpu_spec->cpu_features value. This patch removes the warnings by using the ASM_CONST macro. Signed-off-by:

This patch is originally from Linas Vepstas <linas@linas.org>. This is a dumb, dorky cleanup patch: Per last round of emails, the concept of EEH_REGION is gone, but a few stubs remained. This patch removes them. Signed-off-by:

This patch is from Craig Chaney <cchaney@us.ibm.com>. This patch moves the restoring of the stack pointer in the system call exit path to after the point where we clear the RI (recoverable interrupt) bit in the MSR. Normally, loading the stack pointer before clearing RI doesn't cause any problem because there is no trap that can normally occur in between. But if we are tracing the code using a tool that single-steps instructions, this can cause a problem. In this case, clearing RI serves as an indication that the following code can't be safely single-stepped. Signed-off-by:

This patch is originally from Jake Moilanen <moilanen@austin.ibm.com>, substantially modified by me. On PPC64 systems with a hypervisor, we can't set the Data Address Breakpoint Register (DABR) directly, we have to do it through a hypervisor call. Signed-off-by:

The ppc pci bus and resource fixups will automatically adjust the IO space mappings by (hose->io_base_virt - isa_io_base). Since we map all of PCI IO space (PCI1 & PCI2) with a single mapping so it is continguious in virtual, physical, and PCI IO space the offset will equal MPC85XX_PCI1_IO_SIZE. There for we needed to reduce the setting by that amount for everything to work properly on CDS. Signed-off-by:

With Rik van Riel <riel@redhat.com> Simply running "dd if=/dev/zero of=/dev/hd<one you can miss>" can cause excessive amounts of dirty lowmem pagecache, due to the blockdev's non-highmem page allocation strategy. This patch effectively lowers the dirty limit for mappings which cannot be cached in highmem, counting the dirty limit as a percentage of lowmem instead. This should prevent heavy block device writers from pushing the VM over the edge and triggering OOM kills. Signed-off-by:

When some hardware setups or architectures do not allow OProfile to use performance counters, OProfile operates in timer mode. But, from 2.6.11-rc1, we need to specify the module parameter "timer=1" to work on timer interrupt mode. Change things so that we detect the absence of the high-resolution timer and fall back to timer-based profiling automatically. Furthermore we can easily get oops by reading /dev/oprofile/cpu_type.
