* x86: re-add rdmsrl_safeAndi Kleen2008-04-172-0/+15
| | | | | | | | | | | | | RDMSR for 64bit values with exception handling. Makes it easier to deal with 64bit valued MSRs. The old 64bit code base had that too as checking_rdmsrl(), but it got dropped somehow.

* x86: add set_memory_4k to pageattr.cAndi Kleen2008-04-171-0/+1
| | | | | | | | | | | | | | | | | | | Add a new function to force split large pages into 4k pages. This is needed for some followup optimizations. I had to add a new field to cpa_data to pass down the information that try_preserve_large_page should not run. Right now no set_page_4k() because I didn't need it and all the specialized users I have in mind would be more comfortable with pure addresses. I also didn't export it because it's unlikely external code needs it.

* x86: account overlapped mappings in max_pfn_mappedAndi Kleen2008-04-172-2/+3
| | | | | | | | | | | When end_pfn is not aligned to 2MB (or 1GB) then the kernel might map more memory than end_pfn. Account this in max_pfn_mapped.

* x86: implement true end_pfn_mapped for 32bitAndi Kleen2008-04-172-2/+3
| | | | | | | | | | | | | | Even on 32bit 2MB pages can map more memory than is in the true max_low_pfn if end_pfn is not highmem and not aligned to 2MB. Add a end_pfn_map similar to x86-64 that accounts for this fact. This is important for code that really needs to know about all mapping aliases.

* x86: don't set up early exception handlers for external interruptsAndi Kleen2008-04-171-1/+2
| | | | | | | | | | | | All of early setup runs with interrupts disabled, so there is no need to set up early exception handlers for vectors >= 32 This saves some minor text size.
