| * perf_counter, x86: Set global control MSR correctlyYong Wang2009-06-241-9/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous code made an assumption that the power on value of global control MSR has enabled all fixed and general purpose counters properly. However, this is not the case for certain Intel processors, such as Atom - and it might also be firmware dependent. Each enable bit in IA32_PERF_GLOBAL_CTRL is AND'ed with the enable bits for all privilege levels in the respective IA32_PERFEVTSELx or IA32_PERF_FIXED_CTR_CTRL MSRs to start/stop the counting of respective counters. Counting is enabled if the AND'ed results is true; counting is disabled when the result is false. The end result is that all fixed counters are always disabled on Atom processors because the assumption is just invalid. Fix this by not initializing the ctrl-mask out of the global MSR, but setting it to perf_counter_mask.

* | | alpha: fix percpu build breakageTejun Heo2009-07-011-3/+3
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | alpha percpu access requires custom SHIFT_PERCPU_PTR() definition for modules to work around addressing range limitation. This is done via generating inline assembly using C preprocessing which forces the assembler to generate external reference. This happens behind the compiler's back and makes the compiler think that static percpu variables in modules are unused. This used to be worked around by using __unused attribute for percpu variables which prevent the compiler from omitting the variable; however, recent declare/definition attribute unification change broke this as __used can't be used for declaration. Also, in the process, PER_CPU_ATTRIBUTES definition in alpha percpu.h got broken. This patch adds PER_CPU_DEF_ATTRIBUTES which is only used for definitions and make alpha use it to add __used for percpu variables in modules. This also fixes the PER_CPU_ATTRIBUTES double definition bug.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the link script for ARM to use PAGE_SIZE instead of hard- coded 4096. Also the old RODATA macro is deprecated for the RO_DATA(PAGE_SIZE) macro. As a consequence the PAGE_SIZE was changed from (1UL << PAGE_SHIFT) to (_AC(1,UL) << PAGE_SHIFT) because the linker does not understand the "UL" suffix to numeric constants.

The result can be used for conditional code based on whether device is GP (general purpose), EMU or HS (high security). Also move the type defines so omap1 code compile does not require ifdefs for sections using these defines. This code is needed for the following fix to set the SRAM size correctly for HS omaps. Also at least PM and watchdog code will need this function. Signed-off-by: Kevin Hilman <khilman@ti.deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

This patch adds them back in again. Note that only the .ocr_mask change was /critical/, but I've added the .max_freq setting back as well, as the original sources had it. Can anyone confirm if this is unnecessary? Secondly, there is support in the original code for a 4wire/higher speed mode. As I don't have the requisite N770 hardware (I think it was a rev2 N770?) to test this, I can't really add it back.

Mikael Petterson <mikepe@it.uu.se> reported that at least one of his systems will not boot as a result. We have ruled out the detection algorithm malfunctioning, so it is not a matter of producing the incorrect bitmasks; rather, something in the application of them fails. Revert the commit until we can root cause and correct this problem. -stable team: this means the underlying commit should be rejected.

Until now kvm on s390 did not implement the store facility extended (STFLE) instruction. A 2.6.31-rc kernel that was compiled for z9 or higher did not boot in kvm. This patch implements stfle.
