2008-01-30x86 setup: be more verbose when probing EDDdevzero@web.de
On early boot, probing the Bios for EDD happens without any message. Enhanced Disk Drive Services (EDD) is a mechanism to match x86 BIOS device names (int13 device 80h) to Linux device names (e.g. /dev/sda, /dev/hda) There are buggy Bios out there having problems with EDD. This can be problems with the Bios itself or with addon cards, too. This patch is adds an informational message on early boot. CONFIG_EDD is not set with defconfig, but with allmodconfig (i.e. CONFIG_EDD=m) so the EDD probe may be active on early boot on many systems nowadays. I can tell, that the probe is active on SuSE distro and with that I have seen more than one system hanging endlessly with those "black screen with a blinking cursor in the the upper left" on installation, making it difficult for the end- user to find out, what`s the issue. For sure I have seen this on FujitsuSiemens PCs with i810 and with i815 chipset. This one also honours the "quiet" bootparam.

2008-01-30x86 setup: early cmdline parser handle boolean optionsdevzero@web.de

2008-01-30x86 setup: make PM transition more paranoid; cleanup 32-bit entryH. Peter Anvin
Make the transition to protected mode more paranoid by having back-to-back near jump (to synchronize the 386/486 prefetch queue) and far jump (to set up the code segment.) While we're at it, zero as many registers as practical (for future expandability of the 32-bit entry interface) and enter 32-bit mode with a valid stack. Note that the 32-bit code cannot rely on this stack, or we'll break all other existing users of the 32-bit entrypoint, but it may make debugging hacks easier to write. Signed-off-by: H.

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.

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.
