2007-08-25[POWERPC] cell: Support pinhole-reset on IBM cell bladesArnd Bergmann2-2/+32
The Cell Broadband Engine has a method of injecting a system-reset-exception from an external source into the operating system, which should trigger the regular behaviour of entering xmon or kdump. Unfortunately, the exception handler cannot distinguish it from other interrupt causes by the SRR1 register, which gets used for this on Power 6 and others. IBM Blade servers that want to support triggering the system reset exception using a pinhole button in the front panel therefore use an extra register to determine the reset cause.

2007-08-25[POWERPC] spu_manage: Use newer physical-id attributeChristian Krafft2-6/+2
Legacy device tree used the reg property for the physical id of an spe. On newer device tree layouts the reg property contains the "correct" value in the reg attribute. So there has been intoduced the "physical-id" on newer devicetree layouts. The id is stored by spu_manage into the spu struct as spe_id. cbe_thermal has been changed to use the spu->spe_id. There's no need for the thermal code to check devicetree attributes for itself.

2007-08-23[x86 setup] Volatilize asm() statementsH. Peter Anvin5-29/+30
asm() statements need to be volatile when: a. They have side effects (other than value returned). b. When the value returned can vary over time. c. When they have ordering constraints that cannot be expressed to gcc. In particular, the keyboard and timer reads were violating constraint (b), which resulted in the keyboard/timeout poll getting loop-invariant-removed when compiling with gcc 4.2.0.

2007-08-23sched: sched_clock_idle_[sleep|wakeup]_event()Ingo Molnar1-1/+0
construct a more or less wall-clock time out of sched_clock(), by using ACPI-idle's existing knowledge about how much time we spent idling. This allows the rq clock to work around TSC-stops-in-C2, TSC-gets-corrupted-in-C3 type of problems. ( Besides the scheduler's statistics this also benefits blktrace and printk-timestamps as well. ) Furthermore, the precise before-C2/C3-sleep and after-C2/C3-wakeup callbacks allow the scheduler to get out the most of the period where the CPU has a reliable TSC. This results in slightly more precise task statistics. the ACPI bits were acked by Len. Signed-off-by: Ingo Molnar <[email protected]> Acked-by: Len Brown <[email protected]>

2007-08-22uml: fix previous request size limit fixJeff Dike1-2/+2
The previous patch which limited the number of sectors in a single request to a COWed device was correct in concept, but the limit was implemented in the wrong place. By putting it in ubd_add, it covered the cases where the COWing was specified on the command line. However, when the command line only has the COW file specified, the fact that it's a COW file isn't known until it's opened, so the limit is missed in these cases. This patch moves the sector limit from ubd_add to ubd_open_dev.

2007-08-22[S390] kprobes: fix instruction length calculationDavid Wilder1-1/+1
Placing a kprobe on "bc" instruction (s390/s390x) can cause an oops. The instruction length is encoded into the first two bits of the s390 instruction. Kprobe is incorrectly computing the instruction length. The instruction length is used for determining what type of "fix-up" is needed for conditional branch instruction. The problem can bee seen by placing a kprobe on a "bc" instruction that will not branch. The results is that Kprobe incorrectly computes the new instruction pointer (psw.addr) after single stepping the instruction. The problem is corrected with this patch.

2007-08-22[S390] hypfs: inode corruption due to missing lockingMichael Holzheu1-8/+25
hypfs removes the whole hypfs directory tree and creates a new one, when a process triggers an update by writing to the "update" attribute. When removing and creating files, it is necessary to lock the inode of the parent directory where the files live. Currently hypfs does not lock the parent inode, which can lead to inode corruption.

2007-08-18x86: properly initialize temp insn buffer for paravirt patchingChris Wright1-0/+2
With commit ab144f5ec64c42218a555ec1dbde6b60cf2982d6 the patching code now collects the complete new instruction stream into a temp buffer before finally patching in the new insns. In some cases the paravirt patchers will choose to leave the patch site unpatched (length mismatch, clobbers mismatch, etc). This causes the new patching code to copy an uninitialized temp buffer, i.e. garbage, to the callsite. Simply make sure to always initialize the buffer with the original instruction stream. A better fix is to audit all the patchers and return proper length so that apply_paravirt() can skip copies when we leave the patch site untouched.
