2007-10-01x86_64: increase VDSO_TEXT_OFFSET for ancient binutilsAndi Kleen1-1/+1
For some reason old binutils genertate larger headers so increase the text offset of the vdso to avoid linker errors. Roland McGrath explains: "There are extra symbols in the '.dynsym' section that are responsible for the size difference (They also cause corresponding inflation in '.gnu.version') Older ld's wrongly generated these unneeded symbols in .dynsym. This was fixed not all that long ago (2006); binutils-2.17.50.0.6 might be the first fixed version, but I have not verified for sure where the cutoff was. The unneeded symbols et al from old ld add almost 700 bytes excess. This limits fairly tightly the amount by which the actual text and data in the vDSO can grow in the future without pushing the whole file over 4kb. If it does grow later on, we should consider changing the layout with a config option or something to pack it better without that padding, when building the kernel with newer binutils."

2007-09-26Revert "x86-64: Disable local APIC timer use on AMD systems with C1E"Linus Torvalds1-34/+0
This reverts commit e66485d747505e9d960b864fc6c37f8b2afafaf0, since Rafael Wysocki noticed that the change only works for his in -mm, not in mainline (and that both "noapictimer" _and_ "apicmaintimer" are broken on his hardware, but that's apparently not a regression, just a symptom of the same issue that causes the automatic apic timer disable to not work). It turns out that it really doesn't work correctly on x86-64, since x86-64 doesn't use the generic clock events for timers yet. Thanks to Rafal for testing, and here's the ugly details on x86-64 as per Thomas: "I just looked into the code and the logic vs. noapictimer on SMP is completely broken. On i386 the noapictimer option not only disables the local APIC timer, it also registers the CPUs for broadcasting via IPI on SMP systems. The x86-64 code uses the broadcast only when the local apic timer is active, i.e. "noapictimer" is not on the command line. This defeats the whole purpose of "noapictimer". It should be there to make boxen work, where the local APIC timer actually has a hardware problem, e.g. the nx6325. The current implementation of x86_64 only fixes the ACPI c-states related problem where the APIC timer stops in C3(2), nothing else. On nx6325 and other AMD X2 equipped systems which have the C1E enabled we run into the following: PIT keeps jiffies (and the system) running, but the local APIC timer interrupts can get out of sync due to this C1E effect. I don't think this is a critical problem, but it is wrong nevertheless. I think it's safe to revert the C1E patch and postpone the fix to the clock events conversion." On further reflection, Thomas noted: "It's even worse than I thought on the first check: "noapictimer" on the command line of an SMP box prevents _ONLY_ the boot CPU apic timer from being used. But the secondary CPU is still unconditionally setting up the APIC timer and uses the non calibrated variable calibration_result, which is of course 0, to setup the APIC timer. Wreckage guaranteed." so we'll just have to wait for the x86 merge to hopefully fix this up for x86-64. Tested-and-requested-by: Rafael J.

2007-09-26[x86 setup] Handle case of improperly terminated E820 chainH. Peter Anvin1-7/+23
At least one system (a Geode system with a Digital Logic BIOS) has been found which suddenly stops reporting the SMAP signature when reading the E820 memory chain. We can't know what, exactly, broke in the BIOS, so if we detect this situation, declare the E820 data unusable and fall back to E801. Also, revert to original behavior of always probing all memory methods; that way all the memory information is available to the kernel. Signed-off-by: H.

2007-09-26x86-64: Disable local APIC timer use on AMD systems with C1EThomas Gleixner1-0/+34
commit 3556ddfa9284a86a59a9b78fe5894430f6ab4eef titled [PATCH] x86-64: Disable local APIC timer use on AMD systems with C1E solves a problem with AMD dual core laptops e.g. HP nx6325 (Turion 64 X2) with C1E enabled: When both cores go into idle at the same time, then the system switches into C1E state, which is basically the same as C3. This stops the local apic timer. This was debugged right after the dyntick merge on i386 and despite the patch title it fixes only the 32 bit path. x86_64 is still missing this fix. It seems that mainline is not really affected by this issue, as the PIT is running and keeps jiffies incrementing, but that's just waiting for trouble. -mm suffers from this problem due to the x86_64 high resolution timer patches. This is a quick and dirty port of the i386 code to x86_64. I spent quite a time with Rafael to debug the -mm / hrt wreckage until someone pointed us to this. I really had forgotten that we debugged this half a year ago already. Sigh, is it just me or is there something yelling arch/x86 into my ear?

2007-09-25[POWERPC] Ensure FULL_REGS on execRoland McGrath1-0/+7
When PTRACE_O_TRACEEXEC is used, a ptrace call to fetch the registers at the PTRACE_EVENT_EXEC stop (PTRACE_PEEKUSR) will oops in CHECK_FULL_REGS. With recent versions, "gdb --args /bin/sh -c 'exec /bin/true'" and "run" at the (gdb) prompt is sufficient to produce this. I also have written an isolated test case, see https://bugzilla.redhat.com/show_bug.cgi?id=301791#c15. This change fixes the problem by clearing the low bit of pt_regs.trap in start_thread so that FULL_REGS is true again.

2007-09-19x86-64: page faults from user mode are always user faultsLinus Torvalds1-0/+7
Randy Dunlap noticed an interesting "crashme" behaviour on his dual Prescott Xeon setup, where he gets page faults with the error code having a zero "user" bit, but the register state points back to user mode. This may be a CPU microcode buglet triggered by some strange instruction pattern that crashme generates, and loading a microcode update seems to possibly have fixed it. Regardless, we really should trust the register state more than the error code, since it's really the register state that determines whether we can actually send a signal, or whether we're in kernel mode and need to oops/kill the process in the case of a page fault.

2007-09-19uml: fix irqstack crashJeff Dike3-6/+7
This patch fixes a crash caused by an interrupt coming in when an IRQ stack is being torn down. When this happens, handle_signal will loop, setting up the IRQ stack again because the tearing down had finished, and handling whatever signals had come in. However, to_irq_stack returns a mask of pending signals to be handled, plus bit zero is set if the IRQ stack was already active, and thus shouldn't be torn down. This causes a problem because when handle_signal goes around the loop, sig will be zero, and to_irq_stack will duly set bit zero in the returned mask, faking handle_signal into believing that it shouldn't tear down the IRQ stack and return thread_info pointers back to their original values. This will eventually cause a crash, as the IRQ stack thread_info will continue pointing to the original task_struct and an interrupt will look into it after it has been freed. The fix is to stop passing a signal number into to_irq_stack. Rather, the pending signals mask is initialized beforehand with the bit for sig already set. References to sig in to_irq_stack can be replaced with references to the mask.

Also fix find_victim to not call spu_unbind_context without list_mutex because that violates the above guarantee.

2007-09-17[ARM] 4568/1: fix l2x0 cache invalidate handling of unaligned addressesRui Sousa1-1/+11
The l2x0_inv_range() function doesn't handle unaligned addresses correctly. It's necessary to clean the cache lines that are at the start and end of the invalidate range, if the addresses are not aligned, to prevent corruption of other data sharing the same cache line.

2007-09-16[SPARC64]: Warn user if cpu is ignored.David S. Miller2-2/+10
When NR_CPUS is smaller than the cpu probed, let the user know that the cpu won't be used. Suggested by Al Viro. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-09-16[SPARC64]: Fix lockdep, particularly on SMP.David S. Miller3-26/+58
As noted by Al Viro, when we try to call prom_set_trap_table() in the SMP trampoline code we try to take the PROM call spinlock which doesn't work because the current thread pointer isn't valid yet and lockdep depends upon that being correct. Furthermore, we cannot set the current thread pointer register because it can't be properly dereferenced until we return from prom_set_trap_table(). Kernel TLB misses only work after that call. So do the PROM call to set the trap table directly instead of going through the OBP library C code, and thus avoid the lock altogether. These calls are guarenteed to be serialized fully. Since there are now no calls to the prom_set_trap_table{_sun4v}() library functions, they can be deleted. Signed-off-by: David S. Miller <davem@davemloft.net>
