* Revert "[PATCH] i386/x86_64: Force pci=noacpi on HP XW9300"Linus Torvalds2006-05-301-8/+0
| | | | | | | | | | | | | This reverts commit 5491d0f3e206beb95eeb506510d62a1dab462df1. As per Andi: "After some discussion with people who have the affected system it seems best to revert for 2.6.17. It broke a common BIOS workaround and PCI-X still doesn't work. Alternative is for people to change the BIOS which seems to be better right now." Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86_64: Don't do syscall exit tracing twiceAndi Kleen2006-05-301-6/+1
| | | | | | | | | | | int_ret_from_syscall already does syscall exit tracing, so no need to do it again in the caller. This caused problems for UML and some other special programs doing syscall interception. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86_64: Fix off by one in bad_addr checking in find_e820_areaRobert Hentosh2006-05-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Robert Hentosh <robert_hentosh@dell.com> Actually, we just stumbled on a different bug found in find_e820_area() in e820.c. The following code does not handle the edge condition correctly: while (bad_addr(&addr, size) && addr+size < ei->addr + ei->size) ; last = addr + size; if ( last > ei->addr + ei->size ) continue; The second statement in the while loop needs to be a <= b so that it is the logical negavite of the if (a > b) outside it. It needs to read: while (bad_addr(&addr, size) && addr+size <= ei->addr + ei->size) ; In the case that failed bad_addr was returning an address that is exactly size bellow the end of the e820 range.

* [PATCH] x86_64: Handle empty node zeroDaniel Yeisley2006-05-303-2/+8
| | | | | | | | | | | | | | | From: Daniel Yeisley <dan.yeisley@unisys.com> It is possible to boot a Unisys ES7000 with CPUs from multiple cells, and not also include the memory from those cells. This can create a scenario where node 0 has cpus, but no associated memory. The system will boot fine in a configuration where node 0 has memory, but nodes 2 and 3 do not. [AK: I rechecked the code and generic code seems to indeed handle that already. Dan's original patch had a change for mm/slab.c that seems to be already in now.] Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | From: "Jan Beulich" <jbeulich@novell.com> The PM timer code updates vxtime.last_tsc, but this update was done incorrectly in two ways: - offset_delay being in microseconds requires multiplying with cpu_mhz rather than cpu_khz - the multiplication of offset_delay and cpu_khz (both being 32-bit values) on most current CPUs would overflow (observed value of the delay was approximately 4000us, yielding an overflow for frequencies starting a little above 1GHz) Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] x86_64: Fix stack/mmap randomization for compat tasksAndi Kleen2006-05-301-2/+2
| | | | | | | | | | | | | | | | | ia32_setup_arg_pages would ignore the passed in random stack top and use its own static value. Now it uses the 8bit of randomness native i386 would use too. This indirectly fixes mmap randomization for 32bit processes too, which depends on the stack randomization. Should also give slightly better virtual cache colouring and possibly better performance with HyperThreading.

* | [PATCH] PowerMac: force only suspend-to-disk to be validJohannes Berg2006-05-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a very long time, echoing 'standby' or 'mem' into /sys/power/state has killed the machine on powerpc. This patch fixes that. This patch adds the .valid callback to pm_ops on PowerMac so that only the suspend to disk state can be entered. Note that just returning 0 would suffice since the upper layers don't pass PM_SUSPEND_DISK down, but we handle it there regardless just in case that changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using asm-generic/dma-mapping.h does not work because pushing the call down to pci_alloc_coherent() causes the gfp_t argument of dma_alloc_coherent() to be ignored. Fix this by implementing things directly, and adding a gfp_t argument we can use in the internal call down to the PCI DMA implementation of pci_alloc_coherent(). This fixes massive memory corruption when using the sound driver layer, which passes things like __GFP_COMP down into these routines and (correctly) expects that to work. Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | Problem: If we put a probe onto a callq instruction and the probe is executed, kernel panic of Bad RIP value occurs. Root cause: If resume_execution() found 0xff at first byte of p->ainsn.insn, it must check the _second_ byte. But current resume_execution check _first_ byte again. I changed it checks second byte of p->ainsn.insn. Kprobes on i386 don't have this problem, because the implementation is a little bit different from x86_64.

| | | | | | | | | | | | | | | | | | | | | | | o Kdump second kernel boot fails after a system crash if second kernel is UP and acpi=off and if crash occurred on a non-boot cpu. o Issue here is that MP tables report boot cpu lapic id as 0 but second kernel is booting on a different processor and MP table data is stale in this context. Hence apic_id_registered() check fails in setup_local_APIC() when called from APIC_init_uniprocessor(). o Problem is not seen if ACPI is enabled as in that case boot_cpu_physical_apicid is read from the LAPIC. o Problem is not seen with SMP kernels as well because in this case also boot_cpu_physical_apicid is read from LAPIC. (smp_boot_cpus()). o The problem is fixed by reading boot_cpu_physical_apicid from LAPIC if it is a UP kernel and CRASH_DUMP is enabled.

However, an undefined instruction is used when attempting to restore a non-existent "auxiliary control register". This leads to a crash on S3C2412, which has an ARM926 core instead of an ARM920. At suspend time, the following fragment runs: mrc p15, 0, r7, c2, c0, 0 @ translation table base address mrc p15, 0, r8, c2, c0, 0 @ auxiliary control register mrc p15, 0, r9, c1, c0, 0 @ control register and at resume time, the following fragment runs: mcr p15, 0, r7, c2, c0, 0 @ translation table base mcr p15, 0, r8, c1, c1, 0 @ auxilliary control ... mcr p15, 0, r9, c1, c0, 0 @ turn on MMU, etc There are several problems with these fragments: 1. The ARM920 and ARM926 cores don't have any "auxiliary control register", at least not according to the ARM920 and ARM926 TRM's. 2. The 2nd line of suspend erroneously saves the c2 register again. 3. This saved c2 value is restored using an undefined instruction. For some reason this does not crash on ARM920, but does crash on ARM926. The following patch fixes all these problems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OF trampoline code prom_init.c still needs to identify IBM pSeries (PAPR) machines in order to run some platform specific code on them like instanciating the TCE tables. The code doing that detection was changed recently in 2.6.17 early stages but was done slightly incorrectly. It should be testing for an exact match of "chrp" and it currently tests for anything that begins with "chrp". That means it will incorrectly match with platforms using Maple-like device-trees and have open firmware. This fixes it by using strcmp instead of strncmp to match what the actual platform detection code does.

* | [PATCH] x86_64: Fix memory hotadd heuristicsAndi Kleen2006-05-161-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes some boot failures on Dell and Unisys systems with memory hotadd added. - Set hotadd_percent to 0 by default. This means anybody using hotadd memory needs to specify the value on the command line. That's because there are lots of Intel boxes which have a bogus hotplug area in their SRAT and they would waste a lot of memory before. - Fix calculation of how much memory to use when the hotplug area exceeds hotadd_percent - Fix fallback when the - Fix fallback if memory hotadd is not compiled in.

| | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to see all devices. The system has multiple PCI segments and we don't handle that properly yet in PCI and ACPI. Short term before this is fixed blacklist it to pci=noacpi. Acked-by: len.brown@intel.com Cc: gregkh@suse.de Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

|/ | | | | | | | | | | This triggers for b44's 1GB DMA workaround which tries to map first and then bounces. The 32bit heuristic is reasonable because the IOMMU doesn't attempt to handle < 32bit masks anyways. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
