In this case, we emulate 64k pages with multiple 4k hash PTEs, however in hpte_need_flush() we incorrectly only mask the hardware page size from the address, instead of the logical page size. This causes things to go wrong when we later attempt to iterate through the hardware subpages of the logical page. This patch corrects the error. It has been tested on pSeries bare metal by Michael Neuling. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

On managed CPUs the cpufreq.c core will call driver->exit(cpu) on the managed cpus and powernow_k8 will free the core's data. Later driver->get(cpu) function might get called trying to read out the current freq of a managed cpu and the NULL pointer check does not work on the freed object -> better set it to NULL. ->get() is unsigned and must return 0 as invalid frequency.

This wasn't a problem previously but it now triggers a BUG_ON in xics_set_cpu_priority() because os_cppr->index isn't 0. Fix this problem by setting the index on the CPPR stack to 0 before calling xics_set_cpu_priority() in xics_teardown_cpu(). Also make it clear that we only want to set the priority when there's just one CPPR value in the stack, and enforce it by updating the value of os_cppr->stack[0] rather than os_cppr->stack[os_cppr->index]. While we're at it change the BUG_ON to a WARN_ON.

The problem is that the DWARF info for function epilogues is wrong. Take this standard epilogue sequence, 80003cc4: e3 6f mov r14,r15 80003cc6: 26 4f lds.l @r15+,pr 80003cc8: f6 6e mov.l @r15+,r14 <---- interrupt here 80003cca: f6 6b mov.l @r15+,r11 80003ccc: f6 6a mov.l @r15+,r10 80003cce: f6 69 mov.l @r15+,r9 80003cd0: 0b 00 rts If we take an interrupt at the highlighted point, the DWARF info will bogusly claim that the return address can be found at some offset from the frame pointer, even though the frame pointer was just restored. The worst part is if the unwinder finds a text address at the bogus stack address - unwinding will continue, for a bit, until it finally comes across an unexpected address on the stack and blows up. The only solution is to stop unwinding once we've calculated the function that was executing when the interrupt occurred. This PC can be easily calculated from pt_regs->pc.

This error was causing the DWARF unwinder to pick up the wrong return address on the stack and then unwind using the unwind tables for the wrong function. While I'm here I might as well add CFI annotations for the other registers since they could be useful when unwinding.

However, this causes lost characters on the serial ports. As this is considered non-standard behaviour for Linux, disable the timeout. Note that this will also cause blocking of any deeper omap sleep states. To enable the autoidling of the serial ports, do something like this for each serial port: # echo 5 > /sys/devices/platform/serial8250.0/sleep_timeout # echo 5 > /sys/devices/platform/serial8250.1/sleep_timeout ...

The additional pins exist in omap36xx_cbp_subset, but are not initialized as the superset is missing these offsets. This causes the following errors during the boot: mux: Unknown entry offset 0x236 mux: Unknown entry offset 0x22e mux: Unknown entry offset 0x1ec mux: Unknown entry offset 0x1ee mux: Unknown entry offset 0x1f4 mux: Unknown entry offset 0x1f6 mux: Unknown entry offset 0x1f8 mux: Unknown entry offset 0x1fa mux: Unknown entry offset 0x1fc mux: Unknown entry offset 0x22a mux: Unknown entry offset 0x226 mux: Unknown entry offset 0x230 mux: Unknown entry offset 0x22c mux: Unknown entry offset 0x228 Fix this by adding the missing offsets to omap3 superset. Note that additionally the uninitialized pins need to be skipped on 34xx. Based on an earlier patch by Allen Pais <allen.pais@ti.com>.
