2008-01-30x86: change size of APICIDs from u8 to u16travis@sgi.com
Change the size of APICIDs from u8 to u16. This partially supports the new x2apic mode that will be present on future processor chips. (Chips actually support 32-bit APICIDs, but that change is more intrusive. Supporting 16-bit is sufficient for now). Signed-off-by: Jack Steiner <steiner@sgi.com> I've included just the partial change from u8 to u16 apicids. The remaining x2apic changes will be in a separate patch. In addition, the fake_node_to_pxm_map[] and fake_apicid_to_node[] tables have been moved from local data to the __initdata section reducing stack pressure when MAX_NUMNODES and MAX_LOCAL_APIC are increased in size.

For K8 system: 4G RAM with memory hole remapping enabled, or more than 4G RAM installed. when try to use kexec second kernel, and the first doesn't include gart_shutdown. the second kernel could have different aper position than the first kernel. and second kernel could use that hole as RAM that is still used by GART set by the first kernel. esp. when try to kexec 2.6.24 with sparse mem enable from previous kernel (from RHEL 5 or SLES 10). the new kernel will use aper by GART (set by first kernel) for vmemmap. and after new kernel setting one new GART. the position will be real RAM. the _mapcount set is lost.

2008-01-30x86/pgtable: explain constant sign extension problemJeremy Fitzhardinge
When the _PAGE_FOO constants are defined as (1ul << _PAGE_BIT_FOO), they become unsigned longs. In 32-bit PAE mode, these end up being implicitly cast to 64-bit types when used to manipulate a pte, and because they're unsigned the top 32-bits are 0, destroying the upper bits of the pte. When _PAGE_FOO constants are given a signed integer type, the cast to 64-bits will sign-extend so that the upper bits are all ones, preserving the upper pte bits in manipulations. Explain this in a prominent place.

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.

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.

2008-01-30debug: move WARN_ON() out of lineArjan van de Ven
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...
