2007-09-11[MIPS] Fix aliasing bug in copy_user_highpage.Ralf Baechle
Copy_user_highpage was written assuming it was only being called for breaking COW pages in which case the source page isn't cached as in marked cachable under it kernel virtual address. If it is called anyway the aliasing avoidance strategy implemented by kmap_coherent will fail. Avoid the use of kmap_coherent for pages marked dirty and to avoid another instance of this sort of bug, place a BUG_ON in kmap_coherent. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-09-10i386: fix a hang on stuck nmi watchdogDaniel Walker
In the case when an nmi gets stucks the endflag stays equal to zero. This causes the busy looping on other cpus to continue, even though the nmi test is done. On my machine with out the change below the system would hang right after check_nmi_watchdog(). The change below just sets endflag prior to checking if the test was successful or not.

2007-09-10i386: Fix perfctr watchdog on core duoStephane Eranian
Fix the NMI watchdog on Intel CoreDuo processor where the kernel would get stuck during boot. The issue is related to errata AE49, where the PERFEVTSEL1 counter does not have a working enable bit. Thus it is not possible to use it for NMI. The patch creates a dedicated wd_ops for CoreDuo which falls back to using PERFEVTSEL0. The other Intel processors supporting the architectural PMU will keep on using PERFEVTSEL1 as this allows other subsystems, such as perfmon, to use PERFEVTSEL0 for PEBS monitoring in particular. Bug initially reported by Daniel Walker.

2007-09-10Fix spurious syscall tracing after PTRACE_DETACH + PTRACE_ATTACHRoland McGrath
When PTRACE_SYSCALL was used and then PTRACE_DETACH is used, the TIF_SYSCALL_TRACE flag is left set on the formerly-traced task. This means that when a new tracer comes along and does PTRACE_ATTACH, it's possible he gets a syscall tracing stop even though he's never used PTRACE_SYSCALL. This happens if the task was in the middle of a system call when the second PTRACE_ATTACH was done. The symptom is an unexpected SIGTRAP when the tracer thinks that only SIGSTOP should have been provoked by his ptrace calls so far. A few machines already fixed this in ptrace_disable (i386, ia64, m68k). But all other machines do not, and still have this bug. On x86_64, this constitutes a regression in IA32 compatibility support. Since all machines now use TIF_SYSCALL_TRACE for this, I put the clearing of TIF_SYSCALL_TRACE in the generic ptrace_detach code rather than adding it to every other machine's ptrace_disable.

2007-09-11[POWERPC] ibmebus: Prevent bus_id collisionsJoachim Fenkes
Previously, ibmebus derived a device's bus_id from its location code. The location code is not guaranteed to be unique, so we might get bus_id collisions if two devices share the same location code. The OFDT full_name, however, is unique, so we use that instead (truncating it on the left if it is too long).

2007-09-11[POWERPC] cell/PS3: Ignore storage devices that are still being probedGeert Uytterhoeven
On PS3, A storage device may show up in the repository before the hypervisor has finished probing: - If its type is not yet known, it shows up as PS3_DEV_TYPE_STOR_DUMMY, - If its regions are being probed, it shows up as having zero regions. If any of these happen, consider the device not yet present. The storage probe thread will retry later. This fixes the timing-dependent problem where a kernel booted from FLASH ROM sometimes cannot find the hard disk.

2007-09-11[POWERPC] cell/PS3: Always set master run control bit in mfc_sr1_setJeremy Kerr
At present, running any SPE program on the ps3 will trigger a BUG_ON when spufs_run_spu tries to clear the master run control bit, as lv1 does not make the master run control available to Linux. This change makes SPE apps work again by disabling changes to the master run control on PS3. Although we don't have the facility to disable a SPE with supervisor-level privileges, it's better than hitting the BUG_ON unconditionally.

interrupt. The Cell BE Architecture spec states that the SPU MFC Class 0 interrupt is edge-triggered. The current spu interrupt handler assumes this behavior and does not clear the interrupt status. The PS3 hypervisor visualizes all SPU interrupts as level, and on return from the interrupt handler the hypervisor will deliver a new virtual interrupt for any unmasked interrupts which for which the status has not been cleared. This fix clears the interrupt status in the interrupt handler.

2007-09-05[x86 setup] Work around bug in Xen HVMChristian Ehrhardt
Apparently XEN does not keep the contents of the 48-bit gdt_48 data structure that is passed to lgdt in the XEN machine state. Instead it appears to save the _address_ of the 48-bit descriptor somewhere. Unfortunately this data happens to reside on the stack and is probably no longer availiable at the time of the actual protected mode jump. This is Xen bug but given that there is a one-line patch to work around this problem, the linux kernel should probably do this. My fix is to make the gdt_48 description in setup_gdt static (in setup_idt this is already the case). This allows the kernel to boot under Xen HVM again.
