2008-12-25tracing/ftrace: don't trace on early stage of a secondary cpu boot, v3Frederic Weisbecker
Impact: fix a crash/hard-reboot on certain configs while enabling cpu runtime On some archs, the boot of a secondary cpu can have an early fragile state. On x86-64, the pda is not initialized on the first stage of a cpu boot but it is needed to get the cpu number and the current task pointer. This data is needed during tracing. As they were dereferenced at this stage, we got a crash while tracing a cpu being enabled at runtime. Some other archs like ia64 can have such kind of issue too. Changes on v2: We dropped the previous solution of a per-arch called function to guess the current state of a cpu. That could slow down the tracing. This patch removes the -pg flag on arch/x86/kernel/cpu/common.c where the low level cpu boot functions exist, on start_secondary() and a helper function used at this stage.

2008-12-24x86: disable X86_PTRACE_BTSIngo Molnar
there's a new ptrace arch level feature in .28: config X86_PTRACE_BTS bool "Branch Trace Store" it has broken fork() handling: the old DS area gets copied over into a new task without clearing it. Fixes exist but they came too late: c5dee61: x86, bts: memory accounting bf53de9: x86, bts: add fork and exit handling and are queued up for v2.6.29. This shows that the facility is still not tested well enough to release into a stable kernel - disable it for now and reactivate in .29. In .29 the hardware-branch-tracer will use the DS/BTS facilities too - hopefully resulting in better code. Signed-off-by: Ingo Molnar <mingo@elte.hu>

Impact: cleanup, fix warning This warning: arch/x86/mm/pat.c: In function track_pfn_vma_copy: arch/x86/mm/pat.c:701: warning: passing argument 5 of follow_phys from incompatible pointer type Triggers because physical addresses are resource_size_t, not u64. This really matters when calling an interface like follow_phys() which takes a pointer to a physical address -- although on x86, being littleendian, it would generally work anyway as long as the memory region wasn't completely uninitialized.

2008-12-22x86: prioritize the FPU traps for the error codeH. Peter Anvin
In the case of multiple FPU errors, prioritize the error codes, instead of returning __SI_FAULT, which ends up pushing a 0 as the error code to userspace, a POSIX violation. For i386, we will simply return if there are no errors at all; for x86-64 this is probably a "can't happen" (and the code should be unified), but for this patch, return __SI_FAULT|SI_KERNEL if this ever happens.

2008-12-22sh: Kill off cf-enabler with extreme prejudice.Paul Mundt
Now that the rest of the boards that were using cf-enabler "generically" have switched to setting up their mappings on their own, only the mach-se boards were left using it. All of the cf-enabler using mach-se boards use a special initialization of the MRSHPC windows rather than going through the special PTE as other SH-4 platforms do. This consolidates the MRSHPC setup logic, hooks it up on the boards that care, and gets rid of any and all remaining references to cf-enabler. This has been long overdue, as cf-enabler has been the bane of arch/sh/kernel for the last 7 years. Good riddance. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
