2009-04-13Fix quilt merge error in acpi-cpufreq.cLinus Torvalds
We ended up incorrectly using '&cur' instead of '&readin' in the work_on_cpu() -> smp_call_function_single() transformation in commit 01599fca6758d2cd133e78f87426fc851c9ea725 ("cpufreq: use smp_call_function_[single|many]() in acpi-cpufreq.c"). Andrew explains: "OK, the acpi tree went and had conflicting changes merged into it after I'd written the patch and it appears that I incorrectly reverted part of 18b2646fe3babeb40b34a0c1751e0bf5adfdc64c while fixing the resulting rejects. Switching it to `readin' looks correct." Acked-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This is the second go through of the old DMA_nBIT_MASK macro,and there're not so many of them left,so I put them into one patch.I hope this is the last round. After this the definition of the old DMA_nBIT_MASK macro could be removed.

Atttempting to rid us of the problematic work_on_cpu(). Just use smp_call_fuction_single() here.

2009-04-12x86: fix wrong section of pat_disable & make it staticMarcin Slusarz
pat_disable cannot be __cpuinit anymore because it's called from pat_init and the callchain looks like this: pat_disable [cpuinit] <- pat_init <- generic_set_all <- ipi_handler <- set_mtrr <- (other non init/cpuinit functions) WARNING: arch/x86/mm/built-in.o(.text+0x449e): Section mismatch in reference from the function pat_init() to the function .cpuinit.text:pat_disable() The function pat_init() references the function __cpuinit pat_disable(). This is often because pat_init lacks a __cpuinit annotation or the annotation of pat_disable is wrong. Non CONFIG_X86_PAT version of pat_disable is static inline, so this version can be static too (and there are no callers outside of this file).

2009-04-10x86, intr-remap: fix eoi for interrupt remapping without x2apicWeidong Han
To simplify level irq migration in the presence of interrupt-remapping, Suresh used a virtual vector (io-apic pin number) to eliminate io-apic RTE modification. Level triggered interrupt will appear as an edge to the local apic cpu but still as level to the IO-APIC. So in addition to do the local apic EOI, it still needs to do IO-APIC directed EOI to clear the remote IRR bit in the IO-APIC RTE. Pls refer to Suresh's patch for more details (commit 0280f7c416c652a2fd95d166f52b199ae61122c0). Now interrupt remapping is decoupled from x2apic, it also needs to do the directed EOI for apic. Otherwise, apic interrupts won't work correctly.

2009-04-09mutex: have non-spinning mutexes on s390 by defaultHeiko Carstens
Impact: performance regression fix for s390 The adaptive spinning mutexes will not always do what one would expect on virtualized architectures like s390. Especially the cpu_relax() loop in mutex_spin_on_owner might hurt if the mutex holding cpu has been scheduled away by the hypervisor. We would end up in a cpu_relax() loop when there is no chance that the state of the mutex changes until the target cpu has been scheduled again by the hypervisor. For that reason we should change the default behaviour to no-spin on s390. We do have an instruction which allows to yield the current cpu in favour of a different target cpu. Also we have an instruction which allows us to figure out if the target cpu is physically backed. However we need to do some performance tests until we can come up with a solution that will do the right thing on s390.

The flexible array in the USBH platform data is not safe to copy. The compiler will not allocate any extra memory for the non-init platform data structure (in the *_devices.c files) since it isn't given any defaults at compile time. When the probe function attempts to address that array, it will actually attempt to access data in an adjacent structure. Since there are currently no (known) implementations of the at91 USBH IP with more than 2 vbus pins, I am capping the value at 2. If somebody tries to assign more, then the compiler will produce a warning.

2009-04-08xen: mask XSAVE from cpuidJeremy Fitzhardinge
Xen leaves XSAVE set in cpuid, but doesn't allow cr4.OSXSAVE to be set. This confuses the kernel and it ends up crashing on an xsetbv instruction. At boot time, try to set cr4.OSXSAVE, and mask XSAVE out of cpuid it we can't. This will produce a spurious error from Xen, but allows us to support XSAVE if/when Xen does. This also factors out the cpuid mask decisions to boot time. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

2009-04-08xen: make xen_load_gdt simplerJeremy Fitzhardinge
Remove use of multicall machinery which is unused (gdt loading is never performance critical). This removes the implicit use of percpu variables, which simplifies understanding how the percpu code's use of load_gdt interacts with this code.

2009-04-08xen: split construction of p2m mfn tables from registrationJeremy Fitzhardinge
Build the p2m_mfn_list_list early with the rest of the p2m table, but register it later when the real shared_info structure is in place. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2009-04-08xen: separate p2m allocation from settingJeremy Fitzhardinge
When doing very early p2m setting, we need to separate setting from allocation, so split things up accordingly. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2009-04-08xen: disable preempt for leave_lazy_mmuJeremy Fitzhardinge
xen_mc_flush() requires preemption to be disabled for its own sanity, so disable it while we're flushing. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2009-04-08x86: smarten /proc/interrupts output for new countersHidetoshi Seto
Now /proc/interrupts of tip tree has new counters: PLT: Platform interrupts Format change of output, as like that by commit: commit 7a81d9a7da03d2f27840d659f97ef140d032f609 x86: smarten /proc/interrupts output should be applied to these new counters too.
