CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't really meaningful anymore. It was basically equivalent to PPC64 || 6xx. This removes it along with the following changes: - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely on 6xx which is what they want anyway. - A new symbol, PPC_BOOK3S, is defined that represent compliance with the "Server" variant of the architecture. This is set when either 6xx or PPC64 is set and open the door for future BOOK3E 64-bit. - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use PPC64 && PPC_BOOK3S - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now used to control the use of prom_init.c Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

While we did add support for _PAGE_SPECIAL on some 32-bit platforms, we never actually built get_user_pages_fast() on them. This fixes it which requires a little bit of ifdef'ing around. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

When the console is on a serial port to be driven by serial8250, a character can be lost from the end of the first line in the two-line sequence serial8250.0: ttyS0 at MMIO 0xe0004500 (irq = 42) is a 16550A console handover: boot [udbg0] -> real [ttyS0] This happens because udbg_puts or udbg_write stuff the last byte of the line into the Tx FIFO and return, whereupon the serial8250 initialization code immediately empties that FIFO. The fix: udbg_puts and udbg_write now wait for the Tx FIFO to clear before returning. This delays the system by one additional serial frame time for each line written by udbg, but the effect is not noticeable, a cumulative 17 milliseconds for 200 lines of early printk output at 115200 baud. Also, the routines in udbg_16550.c now emit CRLF instead of LFCR. Linux makes a point of emitting CRLF because, when serial output is captured to a file, LFCR sequences can confuse text editors.

Based on an original patch from Roel Kluin <roel.kluin@gmail.com>. The write size calculated during regs and fpcr writes may currently go negative.

When identify_cpu() is called a second time with a logical PVR, it only copies a subset of the cpu_spec fields so as to avoid overwriting the performance monitor fields that were initialized based on the real PVR. However some of the other, non performance monitor related fields are also not copied: * pvr_mask * pvr_value * mmu_features * machine_check The fact that pvr_mask is not copied can result in show_cpuinfo() showing the cpu as "unknown", if we override an unknown PVR with a logical one - as reported by Shaggy. So change the logic to copy all fields, and then put back the PMC related ones in the case that we're overwriting a real PVR with a logical one.

Setting G5's cpu frequency transition latency to CPUFREQ_ETERNAL stops ondemand governor from working. I measured the latency using sched_clock and haven't seen much higher than 11000ns, so I set this to 12000ns for my configuration. Possibly other configurations will be different? Ideally the generic code would be able to measure it in case the platform does not provide it. But this simple patch at least makes it throttle again.

This reverts commit e088e4c9. Removing the sysfs interface for p4-clockmod was flagged as a regression in bug 12826. Course of action: - Find out the remaining causes of overheating, and fix them if possible. ACPI should be doing the right thing automatically. If it isn't, we need to fix that. - mark p4-clockmod ui as deprecated - try again with the removal in six months. It's not really feasible to printk about the deprecation, because it needs to happen at all the sysfs entry points, which means adding a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

The Freescale Serial Synchronous Interface (SSI) is an audio device present on some Freescale SOCs. Various implementations of the SSI have a different transmit and receive FIFO depth, but are otherwise identical. To support these variations, add a new property fsl,fifo-depth to the SSI node that specifies the depth of the FIFOs. Also update the MPC8610 HPCD device tree with this property.

The interrupt pending register is write 1 clear. If there are more than one external interrupts pending at the same time, acking the first interrupt by reading pending register then OR the corresponding bit and write back to pending register will also clear other interrupt pending bits.

Impact: remove lots of lguest boot WARN_ON() when CONFIG_SPARSE_IRQ=y We now need to call irq_to_desc_alloc_cpu() before set_irq_chip_and_handler_name(), but we can't do that from init_IRQ (no kmalloc available). So do it as we use interrupts instead. Also means we only alloc for irqs we use, which was the intent of CONFIG_SPARSE_IRQ anyway.

Impact: fix lguest boot crash on modern Intel machines The code in early_init_intel does: if (c->x86 > 6 || (c->x86 == 6 && c->x86_model >= 0xd)) { u64 misc_enable; rdmsrl(MSR_IA32_MISC_ENABLE, misc_enable); And that rdmsr faults (not allowed from non-0 PL). We can get around this by mugging the family ID part of the cpuid. 5 seems like a good number. Of course, this is a hack (how very lguest!). We could just indicate that we don't support MSRs, or implement lguest_rdmst.

This is a build fix required after "x86-64: seccomp: fix 32/64 syscall hole" (commit 5b101740). MIPS doesn't have the issue that was fixed for x86-64 by that patch. This also doesn't solve the N32 issue which is that N32 seccomp processes will be treated as non-compat processes thus only have access to N64 syscalls.

In case a ptraced task is reaped (while the tracer is still attached), ds_exit_thread() is called before ptrace_exit(). The latter will release the bts_tracer and remove the thread's ds_ctx. The former will WARN() if the context is not NULL. Oleg Nesterov submitted patches that move ptrace_exit() before exit_thread() and thus reverse the order of the above calls. Remove the bad warning. I will add it again when Oleg's changes are in.
