| * sh: Fix kernel thread stack corruption with preempt.Hideo Saito2007-03-05
| | | | | | | | | | | | | | | | | | | | | | When I run a preemptive kernel-2.6.20 for SH7780, a created kthread(pdflush) can not exit by do_exit() in kernel_thread_helper. I think that the created kthread should have a room for 'struct pt_regs' space on the stack top, because __switch_to() will refer to the space as follows using 'regs = task_pt_regs(prev)' and next condition may be true.

* | [PATCH] CPU hotplug: call check_tsc_sync_source() with irqs offIngo Molnar2007-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | check_tsc_sync_source() depends on being called with irqs disabled (it checks whether the TSC is coherent across two specific CPUs). This is incidentally true during bootup, but not during cpu hotplug __cpu_up(). This got found via smp_processor_id() debugging. disable irqs explicitly and remove the unconditional enabling of interrupts. Add touch_nmi_watchdog() to the cpu_online_map busy loop. this bug is present both on i386 and on x86_64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replaced check_user_space() + __check_access_register with the new check_space(). The old functions made wrong assumptions about kernel and user space when the kernel and user address spaces are switched (kernel in home space, user in primary/secondary space). Secondly the user process can switch to the accress register mode if it is running in primary or secondary mode. In addition it can load an arbitrary value to the access registers. If any other value than 0 for primary space or 1 for secondary space is loaded and memory is accessed using the base register related to the access register, the program should be terminated with a SIGSEGV. To achieve that the DUALD pointer in the DUCT and the PSALD pointer in the PASTE need to point to an array of 8 invalid access-list entries to get a ALEN-translation exception if an invalid alet is used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The illegal operation handler calls the die notifier with DIE_BPT to let kprobes pick up its breakpoint. If kprobes does not find its breakpoint it returns NOTIFY_STOP instead of NOTIFY_DONE. Since we use stop_machine_run on s390 to arm/disarm the kprobes breakpoints the race that kprobe_handler tries to solve by checking for the kprobes breakpoints does not exist. Removing the check makes BUG_ON working again. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

The memory area for this header is also marked as a separate EFI memory descriptor on ia64. The separate EFI memory descriptor is at the moment of the type EFI_UNUSABLE_MEMORY. With such a type the secondary kernel skips over the entire memory granule (config option, 16M or 64M) when detecting memory. If we are lucky we will just lose some memory, but if we happen to have data in the same granule (such as an initramfs image), then this data will never get mapped and the kernel bombs out when trying to access it. So this is an attempt to fix this by changing the EFI memory descriptor type into EFI_LOADER_DATA. This type is the same type used for the kernel data and for initramfs. In the secondary kernel we then handle the ELF core header data the same way as we handle the initramfs image. This patch contains the kernel changes to make this happen. Pretty straightforward, we reserve the area in reserve_memory(). The address for the area comes from the kernel command line and the size comes from the specialized EFI parsing function vmcore_find_descriptor_size().

Unfortunately, the vm_file field is not filled in, so processes with mappings to that memory do not prevent the file from being closed and the memory freed. This results in use-after-free bugs and multiple freeing of pages, etc. I saw this bug on an Altix on SLES9. Haven't reproduced upstream but it looks like the same issue is there.

* | [PATCH] clocksource init adjustments (fix bug #7426)john stultz2007-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch resolves the issue found here: http://bugme.osdl.org/show_bug.cgi?id=7426 The basic summary is: Currently we register most of i386/x86_64 clocksources at module_init time. Then we enable clocksource selection at late_initcall time. This causes some problems for drivers that use gettimeofday for init calibration routines (specifically the es1968 driver in this case), where durring module_init, the only clocksource available is the low-res jiffies clocksource. This may cause slight calibration errors, due to the small sampling time used. It should be noted that drivers that require fine grained time may not function on architectures that do not have better then jiffies resolution timekeeping (there are a few). However, this does not discount the reasonable need for such fine-grained timekeeping at init time. Thus the solution here is to register clocksources earlier (ideally when the hardware is being initialized), and then we enable clocksource selection at fs_initcall (before device_initcall). This patch should probably get some testing time in -mm, since clocksource selection is one of the most important issues for correct timekeeping, and I've only been able to test this on a few of my own boxes.
