2008-01-30x86: unify paravirt pagetable accessorsJeremy Fitzhardinge
Put all the defines for mapping pagetable operations to their native versions (for the non-paravirt case) into one place. Make the corresponding changes to paravirt.h. The tricky part here is that when a pagetable entry can't be updated atomically (ie, 32-bit PAE), we need special handlers for pte_clear, set_pte_atomic and set_pte_present. However, the other two modes don't need special handling for these, and can use a common set_pte(_at) path.

2008-01-30x86: page.h: make pte_t a union to always includeJeremy Fitzhardinge
Make sure pte_t, whatever its definition, has a pte element with type pteval_t. This allows common code to access it without needing to be specifically parameterised on what pagetable mode we're compiling for. For 32-bit, this means that pte_t becomes a union with "pte" and "{ pte_low, pte_high }" (PAE) or just "pte_low" (non-PAE).

2008-01-30x86: make NUMA work on 32-bit againMel Gorman
On 32-bit NUMA, the memmap representing struct pages on each node is allocated from node-local memory if possible. As only node-0 has memory from ZONE_NORMAL, the memmap must be mapped into low memory. This is done by reserving space in the Kernel Virtual Area (KVA) for the memmap belonging to other nodes by taking pages from the end of ZONE_NORMAL and remapping the other nodes memmap into those virtual addresses. The node boundaries are then adjusted so that the region of pages is not used and it is marked as reserved in the bootmem allocator. This reserved portion of the KVA is PMD aligned althought strictly speaking that requirement could be lifted (see thread at http://lkml.org/lkml/2007/8/24/220). The problem is that when aligned, there may be a portion of ZONE_NORMAL at the end that is not used for memmap and does not have an initialised memmap nor is it marked reserved in the bootmem allocator. Later in the boot process, these pages are freed and a storm of Bad page state messages result. This patch marks these pages reserved that are wasted due to alignment in the bootmem allocator so they are not accidently freed. It is worth noting that memory from node-0 is wasted where it could have been put into ZONE_HIGHMEM on NUMA machines. Worse, the KVA is always reserved from the location of real memory even when there is plenty of spare virtual address space. This patch also makes sure that reserve_bootmem() is not called with a 0-length size in numa_kva_reserve(). When this happens, it usually means that a kernel built for Summit is being booted on a normal machine. The resulting BUG_ON() is misleading so it is caught here.

2008-01-30x86: kprobes: add kprobes smoke tests that run on bootAnanth N Mavinakayanahalli
Here is a quick and naive smoke test for kprobes. This is intended to just verify if some unrelated change broke the *probes subsystem. It is self contained, architecture agnostic and isn't of any great use by itself. This needs to be built in the kernel and runs a basic set of tests to verify if kprobes, jprobes and kretprobes run fine on the kernel. In case of an error, it'll print out a message with a "BUG" prefix. This is a start; we intend to add more tests to this bucket over time.

- add support for PER_CPU_ATTRIBUTES - fix generic smp percpu_modcopy to use per_cpu_offset() macro. Add the ability to use generic/percpu even if the arch needs to override several aspects of its operations. This will enable the use of generic percpu.h for all arches. An arch may define: __per_cpu_offset Do not use the generic pointer array. Arch must define per_cpu_offset(cpu) (used by x86_64, s390). __my_cpu_offset Can be defined to provide an optimized way to determine the offset for variables of the currently executing processor. Used by ia64, x86_64, x86_32, sparc64, s/390. SHIFT_PTR(ptr, offset) If an arch defines it then special handling of pointer arithmentic may be implemented. Used by s/390.

2008-01-30i386: handle an initrd in highmem (version 2)H. Peter Anvin
The boot protocol has until now required that the initrd be located in lowmem, which makes the lowmem/highmem boundary visible to the boot loader. This was exported to the bootloader via a compile-time field. Unfortunately, the vmalloc= command-line option breaks this part of the protocol; instead of adding yet another hack that affects the bootloader, have the kernel relocate the initrd down below the lowmem boundary inside the kernel itself. Note that this does not rely on HIGHMEM being enabled in the kernel. Signed-off-by: H.

2008-01-30debug: add the end-of-trace marker and the module list toArjan van de Ven
Unlike oopses, WARN_ON() currently does't print the loaded modules list. This makes it harder to take action on certain bug reports. For example, recently there were a set of WARN_ON()s reported in the mac80211 stack, which were just signalling a driver bug. It takes then anther round trip to the bug reporter (if he responds at all) to find out which driver is at fault. Another issue is that, unlike oopses, WARN_ON() doesn't currently printk the helpful "cut here" line, nor the "end of trace" marker. Now that WARN_ON() is out of line, the size increase due to this is minimal and it's worth adding.

A quick grep shows that there are currently 1145 instances of WARN_ON in the kernel. Currently, WARN_ON is pretty much entirely inlined, which makes it hard to enhance it without growing the size of the kernel (and getting Andrew unhappy). This patch build on top of Olof's patch that introduces __WARN, and places the slowpath out of line. It also uses Ingo's suggestion to not use __FUNCTION__ but to use kallsyms to do the lookup; this saves a ton of extra space since gcc doesn't need to store the function string twice now: 3936367 833603 624736 5394706 525112 vmlinux.before 3917508 833603 624736 5375847 520767 vmlinux-slowpath 15Kb savings...
