2008-02-11x86: vdso_install fixRoland McGrath
The makefile magic for installing the 32-bit vdso images on disk had a little error. A single-line change would fix that bug, but this does a little more to reduce the error-prone duplication of this bit of makefile variable magic.

git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6: [IA64] Fix build for sim_defconfig
2008-02-11[IA64] Fix build for sim_defconfigTony Luck
Commit bdc807871d58285737d50dc6163d0feb72cb0dc2 broke the build for this config because the sim_defconfig selects CONFIG_HZ=250 but include/asm-ia64/param.h has an ifdef for the simulator to force HZ to 32. So we ended up with a kernel/timeconst.h set for HZ=250 ... which then failed the check for the right HZ value and died with: Drop the #ifdef magic from param.h and make force CONFIG_HZ=32 directly for the simulator.

2008-02-11x86: remove over noisy debug printkThomas Gleixner
pageattr-test.c contains a noisy debug printk that people reported. The condition under which it prints (randomly tapping into a mem_map[] hole and not being able to c_p_a() there) is valid behavior and not interesting to report. Remove it.

2008-02-11Use proper abstractions in quirk_intel_irqbalanceMatthew Wilcox
Since we may not have a pci_dev for the device we need to access, we can't use pci_read_config_word. But raw_pci_read is an internal implementation detail; it's better to use the architected pci_bus_read_config_word interface. Using PCI_DEVFN instead of a mysterious constant helps reassure everyone that we really do intend to access device 8. [ Thanks to Grant Grundler for pointing out to me that this is exactly what the write immediately above this is doing -- enabling device 8 to respond to config space cycles. - Matthew Grant also says: "Can you also add a comment which points at the Intel documentation? The 'Intel E7320 Memory Controller Hub (MCH) Datasheet' at http://download.intel.com/design/chipsets/datashts/30300702.pdf Page 69 documents register F4h (DEVPRES1).

2008-02-10Change pci_raw_ops to pci_raw_read/writeMatthew Wilcox
We want to allow different implementations of pci_raw_ops for standard and extended config space on x86. Rather than clutter generic code with knowledge of this, we make pci_raw_ops private to x86 and use it to implement the new raw interface -- raw_pci_read() and raw_pci_write().

2008-02-10PCI x86: always use conf1 to access config space below 256 bytesIvan Kokshaysky
Thanks to Loic Prylli <loic@myri.com>, who originally proposed this idea. Always using legacy configuration mechanism for the legacy config space and extended mechanism (mmconf) for the extended config space is a simple and very logical approach. It's supposed to resolve all known mmconf problems. It still allows per-device quirks (tweaking dev->cfg_size). It also allows to get rid of mmconf fallback code.

2008-02-09[ARM] 4824/1: pxa: clear RDH bit after any resetDmitry Krivoschekov
According to PXA300/310 and PXA320 Developer manuals, the ASCR[RDH] "bit needs to be cleared as part of the software initialization coming out of any reset and coming out of D3". The latter requirement is addressed by commit "c4d1fb627ff3072", as for the former (coming out of any reset), the kernel relies on boot loaders and assumes that RDH bit is cleared there. Though, not all bootloaders follow the rule so we have to clear the bit in kernel. We clear the RDH bit in pxa3xx_init() function since it is always invoked after any reset. We also preserve D1S, D2S and D3S bits from being cleared in case we invoke pxa3xx_init() function not from normal hardware reset (e.g. kexec scenario), so these bits can be properly referenced later.

2008-02-09x86: introduce page pool in cpaThomas Gleixner
DEBUG_PAGEALLOC was not possible on 64-bit due to its early-bootup hardcoded reliance on PSE pages, and the unrobustness of the runtime splitup of large pages. The splitup ended in recursive calls to alloc_pages() when a page for a pte split was requested. Avoid the recursion with a preallocated page pool, which is used to split up large mappings and gets refilled in the return path of kernel_map_pages after the split has been done. The size of the page pool is adjusted to the available memory. This part just implements the page pool and the initialization w/o using it yet.

Makes strtoul smaller, and also we are getting rid of static const char small_digits[] = "0123456789abcdefx"; static const char large_digits[] = "0123456789ABCDEFX"; since this works equally well: static const char digits[16] = "0123456789ABCDEF"; Size savings: $ size vmlinux.org vmlinux text data bss dec hex filename 877320 112252 90112 1079684 107984 vmlinux.org 877048 112252 90112 1079412 107874 vmlinux It may be also a tiny bit faster because code has less branches now, but I doubt it is measurable.

2008-02-09[S390] dynamic page tables.Martin Schwidefsky
Add support for different number of page table levels dependent on the highest address used for a process. This will cause a 31 bit process to use a two level page table instead of the four level page table that is the default after the pud has been introduced. Likewise a normal 64 bit process will use three levels instead of four. Only if a process runs out of the 4 tera bytes which can be addressed with a three level page table the fourth level is dynamically added. Then the process can use up to 8 peta byte.
