2006-08-14[PATCH] Change panic_on_oops message to "Fatal exception"Horms
Previously the message was "Fatal exception: panic_on_oops", as introduced in a recent patch whith removed a somewhat dangerous call to ssleep() in the panic_on_oops path. However, Paul Mackerras suggested that this was somewhat confusing, leadind people to believe that it was panic_on_oops that was the root cause of the fatal exception. On his suggestion, this patch changes the message to simply "Fatal exception". A suitable oops message should already have been displayed.

Also anyone using mem=XXX on boot line and not aligned to MAX_ORDER requires this patch in order to satisfy buddy allocator. vmem_map always starts at pfn 0. The potentially large MAX_ORDER on ia64 (due to hugetlbfs) requires that the end of vmem_map be aligned to MAX_ORDER_NR_PAGES.

2006-08-02[IA64] Do not assume output registers be reservered.Zou Nan hai
We found an issue in pal.S. According to the software runtime SPEC, The caller's output registers do not need to be preserved for caller. The callee may reuse input registers for any other purpose within the procedure. in ia64_pal_call_phys_stacked, input registers are copied to output registers before call into ia64_switch_mode_phys, then used to call into PAL. This assumes output registers are preserved in ia64_switch_mode_phys, which may not be true. In this particular case, ia64_switch_mode_phys alloc a null frame , and mask off psr.i. If an interrupt comes at this small window, or an MCA comes inside the procedure, output registers maybe changed, then the pal call may got some staled input registers. This patch moves the copies from input to output after ia64_switch_mode_phys to follow the software runtime convention. It also removed some unused labels in ia64_pal_call_phys_stacked.

2006-07-31[CPUFREQ] Longhaul - Workaround issues with APIC.Rafa³ Bilski
There is no need to worry about local APIC. There is need to worry about I/O APIC, because I/O APIC is replacing good old 8259. According to Nehemiah datasheet VIA is using 3-wire bus to connect local APIC to I/O APIC. "[...] When IA32_APIC_BASE[11] is set to 0, processor APICs based on the 3-wire APIC bus cannot be generally re-enabled until a system hardware reset. The 3-wire bus looses track of arbitration that would be necessary for complete re-enabling. Certain (local) APIC functionality can be enabled. [...]" So we must set disable bit for each interrupt in I/O APIC registers. Same situation as for PIC - we must poke registers direcly. How to do this? I don't know.

2006-07-31[PATCH] vDSO hash-style fixRoland McGrath
The latest toolchains can produce a new ELF section in DSOs and dynamically-linked executables. The new section ".gnu.hash" replaces ".hash", and allows for more efficient runtime symbol lookups by the dynamic linker. The new ld option --hash-style={sysv|gnu|both} controls whether to produce the old ".hash", the new ".gnu.hash", or both. In some new systems such as Fedora Core 6, gcc by default passes --hash-style=gnu to the linker, so that a standard invocation of "gcc -shared" results in producing a DSO with only ".gnu.hash". The new ".gnu.hash" sections need to be dealt with the same way as ".hash" sections in all respects; only the dynamic linker cares about their contents. To work with older dynamic linkers (i.e. preexisting releases of glibc), a binary must have the old ".hash" section. The --hash-style=both option produces binaries that a new dynamic linker can use more efficiently, but an old dynamic linker can still handle. The new section runs afoul of the custom linker scripts used to build vDSO images for the kernel. On ia64, the failure mode for this is a boot-time panic because the vDSO's PT_IA_64_UNWIND segment winds up ill-formed. This patch addresses the problem in two ways. First, it mentions ".gnu.hash" in all the linker scripts alongside ".hash". This produces correct vDSO images with --hash-style=sysv (or old tools), with --hash-style=gnu, or with --hash-style=both. Second, it passes the --hash-style=sysv option when building the vDSO images, so that ".gnu.hash" is not actually produced. This is the most conservative choice for compatibility with any old userland. There is some concern that some ancient glibc builds (though not any known old production system) might choke on --hash-style=both binaries. The optimizations provided by the new style of hash section do not really matter for a DSO with a tiny number of symbols, as the vDSO has. If someone wants to use =gnu or =both for their vDSO builds and worry less about that compatibility, just change the option and the linker script changes will make any choice work fine.

2006-07-31[PATCH] panic_on_oops: remove ssleep()Horms
This patch is part of an effort to unify the panic_on_oops behaviour across all architectures that implement it. It was pointed out to me by Andi Kleen that if an oops has occured in interrupt context, then calling sleep() in the oops path will only cause a panic, and that it would be really better for it not to be in the path at all. This patch removes the ssleep() call and reworks the console message accordinly. I have a slght concern that the resulting console message is too long, feedback welcome. For powerpc it also unifies the 32bit and 64bit behaviour. Fror x86_64, this patch only updates the console message, as ssleep() is already not present.

The kprobe-booster's safety check against preemption does not work well now, because the preemption count has been modified by read_rcu_lock() in atomic_notifier_call_chain() before we check it. So, I'd like to prevent boosting kprobe temporarily if the kernel is preemptable. Now we are searching for the good solution.

2006-07-31[PATCH] synchronize_tsc() fixesAndrew Morton
- Move the tsc synchronisation variables into a struct, mark it __initdata - local `realdelta' wants to be 64-bit - Print the skew for negative skews, as well as for positive ones - remove dead code Cc: john stultz <johnstul@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-07-31[IA64] Format /proc/pal/*/version_info correctlyMatthew Wilcox
/proc/pal/*/version_info is a bit confusing. HP firmware, at least, reports 07.31 instead of 0.7.31. Also, the comment is out of place; it's an internal detail about the implementation of ia64_pal_version. Since the 2.2 revision of the SDM still states that PAL_VERSION can be called in virtual mode, correct the comment to be more accurate.
