2010-02-22PCI PM: Make it possible to force using INTx for PCIe PME signalingRafael J. Wysocki
Apparently, some machines may have problems with PCI run-time power management if MSIs are used for the native PCIe PME signaling. In particular, on the MSI Wind U-100 PCIe PME interrupts are not generated by a PCIe root port after a resume from suspend to RAM, if the system wake-up was triggered by a PME from the device attached to this port. [It doesn't help to free the interrupt on suspend and request it back on resume, even if that is done along with disabling the MSI and re-enabling it, respectively.] However, if INTx interrupts are used for this purpose on the same machine, everything works just fine. For this reason, add a kernel command line switch allowing one to request that MSIs be not used for the native PCIe PME signaling, introduce a DMI table allowing us to blacklist machines that need this switch to be set by default and put the MSI Wind U-100 into this table.

2010-02-22PCI PM: PCIe PME root port service driverRafael J. Wysocki
PCIe native PME detection mechanism is based on interrupts generated by root ports or event collectors every time a PCIe device sends a PME message upstream. Once a PME message has been sent by an endpoint device and received by its root port (or event collector in the case of root complex integrated endpoints), the Requester ID from the message header is registered in the root port's Root Status register. At the same time, the PME Status bit of the Root Status register is set to indicate that there's a PME to handle. If PCIe PME interrupt is enabled for the root port, it generates an interrupt once the PME Status has been set. After receiving the interrupt, the kernel can identify the PCIe device that generated the PME using the Requester ID from the root port's Root Status register. [For details, see PCI Express Base Specification, Rev. 2.0.] Implement a driver for the PCIe PME root port service working in accordance with the above description.

2010-02-20ARM: allow alignment fault mode to be configured at kernel bootRussell King
Some glibc versions intentionally create lots of alignment faults in their gconv code, which if not fixed up, results in segfaults during boot. This can prevent systems booting properly. There is no clear hard-configurable default for this; the desired default depends on the nature of the userspace which is going to be booted. So, provide a way for the alignment fault handler to be configured via the kernel command line. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Now that numa=fake=<size>[MG] is implemented, it is possible to remove configurable node size support.

2010-02-15x86, numa: Add fixed node size option for numa emulationDavid Rientjes
numa=fake=N specifies the number of fake nodes, N, to partition the system into and then allocates them by interleaving over physical nodes. This requires knowledge of the system capacity when attempting to allocate nodes of a certain size: either very large nodes to benchmark scalability of code that operates on individual nodes, or very small nodes to find bugs in the VM. This patch introduces numa=fake=<size>[MG] so it is possible to specify the size of each node to allocate. When used, nodes of the size specified will be allocated and interleaved over the set of physical nodes. FAKE_NODE_MIN_SIZE was also moved to the more-appropriate include/asm/numa_64.h.

2010-01-25mm: add coherence API for DMA to vmalloc/vmap areasJames Bottomley
On Virtually Indexed architectures (which don't do automatic alias resolution in their caches), we have to flush via the correct virtual address to prepare pages for DMA. On some architectures (like arm) we cannot prevent the CPU from doing data movein along the alias (and thus giving stale read data), so we not only have to introduce a flush API to push dirty cache lines out, but also an invalidate API to kill inconsistent cache lines that may have moved in before DMA changed the data Signed-off-by: James Bottomley <James.Bottomley@suse.de>

Commit d899bf7b (procfs: provide stack information for threads) introduced to show stack information in /proc/{pid}/status. But it cause large performance regression. Unfortunately /proc/{pid}/status is used ps command too and ps is one of most important component. Because both to take mmap_sem and page table walk are heavily operation. If many process run, the ps performance is, [before d899bf7b] % perf stat ps >/dev/null Performance counter stats for 'ps': 4090.435806 task-clock-msecs # 0.032 CPUs 229 context-switches # 0.000 M/sec 0 CPU-migrations # 0.000 M/sec 234 page-faults # 0.000 M/sec 8587565207 cycles # 2099.425 M/sec 9866662403 instructions # 1.149 IPC 3789415411 cache-references # 926.409 M/sec 30419509 cache-misses # 7.437 M/sec 128.859521955 seconds time elapsed [after d899bf7b] % perf stat ps > /dev/null Performance counter stats for 'ps': 4305.081146 task-clock-msecs # 0.028 CPUs 480 context-switches # 0.000 M/sec 2 CPU-migrations # 0.000 M/sec 237 page-faults # 0.000 M/sec 9021211334 cycles # 2095.480 M/sec 10605887536 instructions # 1.176 IPC 3612650999 cache-references # 839.160 M/sec 23917502 cache-misses # 5.556 M/sec 152.277819582 seconds time elapsed Thus, this patch revert it. Fortunately /proc/{pid}/task/{tid}/smaps provide almost same information. we can use it. Commit d899bf7b introduced two features: 1) Add the annotattion of [thread stack: xxxx] mark to /proc/{pid}/task/{tid}/maps. 2) Add StackUsage field to /proc/{pid}/status. I only revert (2), because I haven't seen (1) cause regression.
