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:

When a machine check or NMI occurs while multiple byte code is patched the CPU could theoretically see an inconsistent instruction and crash. Prevent this by temporarily disabling MCEs and returning early in the NMI handler. Based on discussion with Mathieu Desnoyers.

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. Contains bug fixes from Zach Amsden and suggestions from Mathieu Desnoyers.

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. AK: Enabling by default for i386 will be likely controversal, but let's see what happens AK: Really folks, before complaining just fix your segfaults AK: I bet this will find a lot of silent issues Signed-off-by:Masoud Sharbiani <masouds@google.com> Signed-off-by:

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.

Classic 32-bit PowerPC CPUs, and the early 64-bit PowerPC CPUs, don't provide a way to prevent execution from readable pages, that is, the MMU doesn't distinguish between data reads and instruction reads, although a different exception is taken for faults in data accesses and instruction accesses. Commit 9ba4ace3, in the course of fixing another bug, added a check that meant that a page fault due to an instruction access would fail if the vma did not have the VM_EXEC flag set. This gives an inconsistent enforcement on these CPUs of the no-execute status of the vma (since reading from the page is sufficient to allow subsequent execution from it), and causes old versions of ppc32 glibc (2.2 and earlier) to fail, since they rely on executing the word before the GOT but don't have it marked executable. This fixes the problem by allowing execution from readable (or writable) areas on CPUs which do not provide separate control over data and instruction reads. Signed-off-by:

Move firmware feature initialisation from pSeries_init_early to the earlier pSeries_probe_hypertas so they are initialised before firmware feature fixups are applied. Currently firmware feature sections are only used for iSeries which initialises the these features much earlier. This is a bug in waiting on pSeries. Also adds some whitespace fixups. Signed-off-by:
