2009-05-01x86: initialize io_bitmap_base on 32bitThomas Gleixner
commit db949bba3c7cf2e664ac12e237c6d4c914f0c69d (x86-32: use non-lazy io bitmap context switching) broke ioperm for 32bit because it removed the lazy initialization of io_bitmap_base and did not set it to the real bitmap offset.

2009-04-29perf_counter, x86: return raw count with x86_perf_counter_update()Robert Richter
To check on AMD cpus if a counter overflows, the upper bit of the raw counter value must be checked. This value is already internally available in x86_perf_counter_update().

2009-04-29perf_counter, x86: implement the interrupt handler for AMD cpusRobert Richter
This patch implements the interrupt handler for AMD performance counters. In difference to the Intel pmu, there is no single status register and also there are no fixed counters. This makes the handler very different and it is useful to make the handler vendor specific. To check if a counter is overflowed the upper bit of the counter is checked. Only counters where the active bit is set are checked. With this patch throttling is enabled for AMD performance counters. This patch also reenables Linux performance counters on AMD cpus.

2009-04-29perf_counter, x86: change and remove pmu initialization checksRobert Richter
Some functions are only called if the pmu was proper initialized. That initalization checks can be removed. The way to check initialization changed too. Now, the pointer to the interrupt handler is checked. If it exists the pmu is initialized. This also removes a static variable and uses struct x86_pmu as only data source for the check.

2009-04-29perf_counter, x86: rework counter enable functionsRobert Richter
There is vendor specific code in generic x86 code, and there is vendor specific code that could be generic. This patch introduces x86_pmu_enable_counter() for x86 generic code. Fixed counter code for Intel is moved to Intel only functions. In the end, checks and calls via function pointers were reduced to the necessary. Also, the internal function i/f changed.

2009-04-29x86, vmlinux.lds: unify data output sectionsSam Ravnborg
For 64 bit the following functional changes are introduced: - .data.page_aligned has moved - .data.cacheline_aligned has moved - .data.read_mostly has moved - ALIGN() moved out of output section for .data.cacheline_aligned - ALIGN() moved out of output section for .data.page_aligned Notice that 32 bit and 64 bit has different location of _edata. .data_nosave is 32 bit only as 64 bit is special due to PERCPU.
