* [PATCH] i386: fix uses of user_mode() vs. user_mode_vm()Jan Beulich2006-03-23

This is useful for Xen > because it will need only to redefine only the macro to a hypervisor call. I am of the opinion that the above changeset is incomplete, i.e. it missed converting some previous uses of user_mode to user_mode_vm. While most of them could be considered just cosmetical, at least the one in die_nmi doesn't appear to be.

* [PATCH] i386: actively synchronize vmalloc area when registering certain ↵Jan Beulich2006-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | callbacks Registering a callback handler through register_die_notifier() is obviously primarily intended for use by modules. However, the way these currently get called it is basically impossible for them to actually be used by modules, as there is, on non-PAE configurationes, a good chance (the larger the module, the better) for the system to crash as a result. This is because the callback gets invoked (a) in the page fault path before the top level page table propagation gets carried out (hence a fault to propagate the top level page table entry/entries mapping to module's code/data would nest infinitly) and (b) in the NMI path, where nested faults must absolutely not happen, since otherwise the IRET from the nested fault re-enables NMIs, potentially resulting in nested NMI occurences. Besides the modular aspect, similar problems would even arise for in- kernel consumers of the API if they touched ioremap()ed or vmalloc()ed memory inside their handlers.

* [PATCH] x86: early printk handling fixesStas Sergeev2006-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The history is that -mm kernels do not work for me for a few months already. The things started from crashing somewhere after starting init, and for the last month - no boot at all, just "Uncompressing... OK, booting kernel", and silence. Early console didn't work too. With the latest releases this degraded into an infinite stream of the "Unknown interrupt or fault" messages. So today my patience ran out and I started to think how can I collect at least some info for the bug-report. Attached is the patch that allows to gather some valueable debug info on the problem by making an early console more useable. I can't properly test the patch, as the kernel still doesn't boot, so I'll explain it in details in a hope someone else can justify the intrusive changes. arch_hooks.h: added prototypes for setup_early_printk() and early_printk(). setup.c: killed wrong setup_early_printk() prototype. Moved setup_early_printk() a bit earlier, as it was not "early enough" to cover the bug I was fighting with. early_printk.c: made it to start printing from the bottom of the screen, otherwise the messages interfere with the ones of the boot-loader, so you can't read them.

* [PATCH] x86: SMP alternativesGerd Hoffmann2006-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement SMP alternatives, i.e. switching at runtime between different code versions for UP and SMP. The code can patch both SMP->UP and UP->SMP. The UP->SMP case is useful for CPU hotplug. With CONFIG_CPU_HOTPLUG enabled the code switches to UP at boot time and when the number of CPUs goes down to 1, and switches to SMP when the number of CPUs goes up to 2. Without CONFIG_CPU_HOTPLUG or on non-SMP-capable systems the code is patched once at boot time (if needed) and the tables are released afterwards. The changes in detail: * The current alternatives bits are moved to a separate file, the SMP alternatives code is added there. * The patch adds some new elf sections to the kernel: .smp_altinstructions like .altinstructions, also contains a list of alt_instr structs. .smp_altinstr_replacement like .altinstr_replacement, but also has some space to save original instruction before replaving it. .smp_locks list of pointers to lock prefixes which can be nop'ed out on UP. The first two are used to replace more complex instruction sequences such as spinlocks and semaphores. It would be possible to deal with the lock prefixes with that as well, but by handling them as special case the table sizes become much smaller. * The sections are page-aligned and padded up to page size, so they can be free if they are not needed. * Splitted the code to release init pages to a separate function and use it to release the elf sections if they are unused.

Luckily before it passes paddr (calculated from paddr) to the hpte_insert routines it calls virt_to_abs() (aka. __pa()) on the address, so there isn't actually a bug. map_io_page() however does pass pstart properly, so currently it's broken AFAICT because we're calling __pa(paddr) which will get us something very large. Presumably no one's calling map_io_page() in the right context. Anyway, change htab_bolt_mapping() callers to properly pass pstart, and then use it properly in htab_bolt_mapping(), ie. don't call __pa() on it again. Booted on p5 LPAR, iSeries and Power3.

Set nodes online as resources are scanned. Fall back to node 0 only when we're sure this isn't a NUMA machine.

| | * | | [PATCH] powerpc: add a raw dump command to xmonOlaf Hering2006-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dump a stream of rawbytes with a new 'dr' command. Produces less output and it is simpler to feed the output to scripts. Also, dr has no dumpsize limits. Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Paul Mackerras <paulus@samba.org>
