2014-05-07ACPICA: acpidump: Fix code issue in invoking fread in the loop.Lv Zheng1-11/+6
This patch fixes an issue that the while loop is not needed as fread() should return exact the bytes of expected. The patch is tested by runing diff against the output of "-c" mode and the normal mode, and only finds the following differences: 1. table addresses: the "-c" mode will always fill 0x0000000000000000 for the address. 2. RSDP/RSDT/XSDT: there is no generation of such tables for "-c" mode. So the test result shows the fix is valid. Lv Zheng.

2014-05-04vexpress: Initialise the sysregs before setting up the clocksCatalin Marinas1-0/+2
Following arm64 commit bc3ee18a7a57 (arm64: init: Move of_clk_init to time_init()), vexpress_osc_of_setup() is called via of_clk_init() long before initcalls are issued. Initialising the vexpress oscillators requires the vespress sysregs to be already initialised, so this patch adds an explicit call to vexpress_sysreg_of_early_init() in vexpress oscillator setup function.

2014-05-04arm64: fixmap: fix missing sub-page offset for earlyprintkMarc Zyngier2-4/+5
Commit d57c33c5daa4 (add generic fixmap.h) added (among other similar things) set_fixmap_io to deal with early ioremap of devices. More recently, commit bf4b558eba92 (arm64: add early_ioremap support) converted the arm64 earlyprintk to use set_fixmap_io. A side effect of this conversion is that my virtual machines have stopped booting when I pass "earlyprintk=uart8250-8bit,0x3f8" to the guest kernel. Turns out that the new earlyprintk code doesn't care at all about sub-page offsets, and just assumes that the earlyprintk device will be page-aligned. Obviously, that doesn't play well with the above example. Further investigation shows that set_fixmap_io uses __set_fixmap instead of __set_fixmap_offset. A fix is to introduce a set_fixmap_offset_io that uses the latter, and to remove the superflous call to fix_to_virt (which only returns the value that set_fixmap_io has already given us). With this applied, my VMs are back in business. Tested on a Cortex-A57 platform with kvmtool as platform emulation.

Fix for the arm64 kern_addr_valid() function to recognize virtual addresses in the kernel logical memory map. The function fails as written because it does not check whether the addresses in that region are mapped at the pmd level to 2MB or 512MB pages, continues the page table walk to the pte level, and issues a garbage value to pfn_valid().

As trace event triggers are now part of the mainline kernel, I added my trace event trigger tests to my test suite I run on all my kernels. Now these tests get run under different config options, and one of those options is CONFIG_PROVE_RCU, which checks under lockdep that the rcu locking primitives are being used correctly.

2014-05-01parisc: remove _STK_LIM_MAX overrideJohn David Anglin1-1/+0
There are only a couple of architectures that override _STK_LIM_MAX to a non-infinity value. This changes the stack allocation semantics in subtle ways. For example, GNU make changes its stack allocation to the hard maximum defined by _STK_LIM_MAX. As a results, threads executed by processes running under make are allocated a stack size of _STK_LIM_MAX rather than a sensible default value. This causes various thread stress tests to fail when they can't muster more than about 50 threads. The attached change implements the default behavior used by the majority of architectures.

2014-05-01Revert "hwmon: (coretemp) Refine TjMax detection"Guenter Roeck1-2/+2
This reverts commit 9fb6c9c73b11bef65ba80a362547fd116c1e1c9d. Tjmax on some Intel CPUs is below 85 degrees C. One known example is L5630 with Tjmax of 71 degrees C. There are other Xeon processors with Tjmax of 70 or 80 degrees C. Also, the Intel IA32 System Programming document states that the temperature target is in bits 23:16 of MSR 0x1a2 (MSR_TEMPERATURE_TARGET), which is 8 bits, not 7. So even if turbostat uses similar checks to validate Tjmax, there is no evidence that the checks are actually required. On the contrary, the checks are known to cause problems and therefore need to be removed. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=75071.

2014-05-01ACPI / processor: Fix failure of loading acpi-cpufreq driverLan Tianyu1-3/+4
According commit d640113fe (ACPI: processor: fix acpi_get_cpuid for UP processor), BIOS may not provide _MAT or MADT tables and acpi_get_apicid() always returns -1. For these cases, original code will pass apic_id with vaule of -1 to acpi_map_cpuid() and it will check the acpi_id. If acpi_id is equal to zero, ignores apic_id and return zero for CPU0. Commit b981513 (ACPI / scan: bail out early if failed to parse APIC ID for CPU) changed the behavior. Return ENODEV when find apic_id is less than zero after calling acpi_get_apicid(). This causes acpi-cpufreq driver fails to be loaded on some machines. This patch is to fix it.

2014-05-01PNP / ACPI: Do not return errors if _DIS or _SRS are not presentRafael J. Wysocki1-18/+26
The ACPI PNP subsystem returns errors from pnpacpi_set_resources() and pnpacpi_disable_resources() if the _SRS or _DIS methods are not present, respectively, but it should not do that, because those methods are optional. For this reason, modify pnpacpi_set_resources() and pnpacpi_disable_resources(), respectively, to ignore missing _SRS or _DIS. This problem has been uncovered by commit 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace) and manifested itself by causing serial port suspend to fail on some systems.
