Due to index register access ordering problems, when using macros a line like this fails (and does nothing): setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88); With inlined functions this line will work as expected. Note about a side effect: Seems on Geode GX1 based systems the "suspend on halt power saving feature" was never enabled due to this wrong macro expansion. With inlined functions it will be enabled, but this will stop the TSC when the CPU runs into a HLT instruction. Kernel output something like this: Clocksource tsc unstable (delta = -472746897 ns) This is the 3rd version of this patch. - Adding missed arch/i386/kernel/cpu/mtrr/state.c Thanks to Andres Salomon - Adding some big fat comments into the new header file Suggested by Andi Kleen AK: fixed x86-64 compilation Signed-off-by: NJuergen Beisert <juergen@kreuzholzen.de> Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Reenable kprobes and alternative patching when the kernel text is write protected by DEBUG_RODATA Add a general utility function to change write protected text. The new function remaps the code using vmap to write it and takes care of CPU synchronization. It also does CLFLUSH to make icache recovery faster. There are some limitations on when the function can be used, see the comment. This is a newer version that also changes the paravirt_ops code. text_poke also supports multi byte patching now.

This patch makes the i386 behave the same way that x86_64 does when a segfault happens. A line gets printed to the kernel log so that tools that need to check for failures can behave more uniformly between debug.show_unhandled_signals sysctl variable to 0 (or by doing echo 0 > /proc/sys/debug/exception-trace) Also, all of the lines being printed are now using printk_ratelimit() to deny the ability of DoS from a local user with a program like the following: main() { while (1) if (!fork()) *(int *)0 = 0; } This new revision also includes the fix that Andrew did which got rid of new sysctl that was added to the system in earlier versions of this. Also, 'show-unhandled-signals' sysctl has been renamed back to the old 'exception-trace' to avoid breakage of people's scripts.

Selinux folks had been complaining about the lack of AVC_PATH records when audit is disabled. I must admit my stupidity - I assumed that avc_audit() really couldn't use audit_log_d_path() because of deadlocks (== could be called with dcache_lock or vfsmount_lock held). Shouldn't have made that assumption - it never gets called that way. It _is_ called under spinlocks, but not those. Since audit_log_d_path() uses ab->gfp_mask for allocations, kmalloc() in there is not a problem. IOW, the simple fix is sufficient: let's rip AUDIT_AVC_PATH out and simply generate pathname as part of main record. It's trivial to do.

The sanity check in audit_match_class() is wrong. We are able to audit 2048 syscalls but in audit_match_class() we were accidentally using sizeof(_u32) instead of number of bits in _u32 when deciding how many syscalls were valid. On ia64 in particular we were hitting syscall numbers over the (wrong) limit of 256. Fixing the audit_match_class check takes care of the problem.

Some HW platforms, such as the new cell blades, requires some MPIC sources to be left alone by the operating system. This implements support for a "protected-sources" property in the mpic controller node containing a list of source numbers to be protected against operating system interference. For those interested in the gory details, the MPIC on the southbridge of those blades has some of the processor outputs routed to the cell, and at least one routed as a GPIO to the service processor. It will be used in the GA product for routing some of the southbridge error interrupts to the service processor which implements some of the RAS stuff, such as checkstopping when fatal errors occurs before they can propagate.
