* x86: disable apm on the olpcJeremy Katz2008-09-241-1/+2
| | | | | | | | The OLPC doesn't support APM but also doesn't have DMI, so we can't detect and disable it based on DMI data. So, just disable based on machine_is_olpc() Signed-off-by: Jeremy Katz <katzj@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| * x86: c1e_idle: don't mark TSC unstable if CPU has invariant TSCAndreas Herrmann2008-09-231-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: Functional TSC is marked unstable on AMD family 0x10 and 0x11 CPUs. This would be wrong because for those CPUs "invariant TSC" means: "The TSC counts at the same rate in all P-states, all C states, S0, or S1" (See "Processor BIOS and Kernel Developer's Guides" for those CPUs.)

| | | | | | | | | | | | | | | | | | | | Impact: System hang when AMD C1E machines switch into C2/C3 AMD C1E enabled systems do not work with normal ACPI C-states even if the BIOS is advertising them.

| * x86: prevent stale state of c1e_mask across CPU offline/onlineThomas Gleixner2008-09-233-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: hang which happens across CPU offline/online on AMD C1E systems. When a CPU goes offline then the corresponding bit in the broadcast mask is cleared. For AMD C1E enabled CPUs we do not reenable the broadcast when the CPU comes online again as we do not clear the corresponding bit in the c1e_mask, which keeps track which CPUs have been switched to broadcast already. So on those !$@#& machines we never switch back to broadcasting after a CPU offline/online cycle. Clear the bit when the CPU plays dead. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 27-rc fails to boot up if configured to use modules. Turns out vsmp_patch was marked __init, and vsmp_patch being the pvops 'patch' routine for vsmp, a call to vsmp_patch just turns out to execute a code page with series of 0xcc (POISON_FREE_INITMEM -- int3). vsmp_patch has been marked with __init ever since pvops, however, apply_paravirt can be called during module load causing calls to freed memory location. Since apply_paravirt can only be called during init/module load, make vsmp_patch with "__init_or_module" Signed-off-by: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

The kexec utility then includes uncached memory as part of vmcore. The kdump kernel MCA'ed when it tries to save the vmcore to a disk. A normal "cached" access may cause MCAs. This patch would label memory with attribute of EFI_MEMORY_UC only as "Uncached RAM" so that kexec would know not to include it in the vmcore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon a bug report by Meelis Roos. The OF device layer builds properties by matching bus types and applying 'range' properties as appropriate, up to the root. The match for "PCI" busses is looking at the 'device_type' property, and this does work %99 of the time. But on an E3500 system with a PCI QFE card, the DEC 21153 bridge sitting above the QFE network interface devices has a 'name' of "pci", but it completely lacks a 'device_type' property. So we don't match it as a PCI bus, and subsequently we end up with no resource values at all for the devices sitting under that DEC bridge. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For Freescale 8xxx devices that use an MPIC, the interrupt numbers in the device tree must be 16 greater than the values documented in the reference manual. In these chips, the MPIC is wired to use the first 16 numbers for external interrupts, but the documentation numbers internal interrupts from 0. In the MPC8610 HPCD device tree, the interrupt properties for the DMA channels for DMA2 were not the adjusted values. This fixes that.

This can't be correct, it breaks rcu (at least the preempt version) and lockdep.

System calls don't use the stack -- they borrow a callee-saved register instead. This means that syscalls that take 6 parameters must be called through a stub that pushes the last parameter on the stack. This patch adds a stub for sync_file_range syscall on AVR32 architecture.

Any function call can try to access the current thread register via the _mcount hooks when the kernel is built with -pg (via ftrace or STACK_DEBUG). That can't be setup properly very early on during the bootup of other cpus for sun4u and some early sun4v systems. So add notrace markers to these specific functions, so that _mcount doesn't get invoked too early. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCI_DMA_BUS_IS_PHYS was defined to be zero, which meant we ignored the DMA mask for IDE and SCSI transfers. This is wrong - we have no DMA translation hardware. We want to obey DMA masks so that the block layer performs bouncing itself.
