2010-02-20ARM: make_coherent(): fix problems with highpte, part 2Russell King
update_mmu_cache() is called with the page table for the faulted-in page still mapped. We need to modify the PTE for this page to ensure coherency with other shared mappings when multiple shared mappings exist within a MM. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-02-20MM: Pass a PTE pointer to update_mmu_cache() rather than the PTE itselfRussell King
On VIVT ARM, when we have multiple shared mappings of the same file in the same MM, we need to ensure that we have coherency across all copies. We do this via make_coherent() by making the pages uncacheable. This used to work fine, until we allowed highmem with highpte - we now have a page table which is mapped as required, and is not available for modification via update_mmu_cache(). Ralf Beache suggested getting rid of the PTE value passed to update_mmu_cache(): On MIPS update_mmu_cache() calls __update_tlb() which walks pagetables to construct a pointer to the pte again. Passing a pte_t * is much more elegant. Maybe we might even replace the pte argument with the pte_t? Ben Herrenschmidt would also like the pte pointer for PowerPC: Passing the ptep in there is exactly what I want. I want that -instead- of the PTE value, because I have issue on some ppc cases, for I$/D$ coherency, where set_pte_at() may decide to mask out the _PAGE_EXEC. So, pass in the mapped page table pointer into update_mmu_cache(), and remove the PTE value, updating all implementations and call sites to suit.

2010-02-20ARM: allow alignment fault mode to be configured at kernel bootRussell King
Some glibc versions intentionally create lots of alignment faults in their gconv code, which if not fixed up, results in segfaults during boot. This can prevent systems booting properly. There is no clear hard-configurable default for this; the desired default depends on the nature of the userspace which is going to be booted. So, provide a way for the alignment fault handler to be configured via the kernel command line. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2010-02-19x86: Initialize stack canary in secondary startJacob Pan

2010-02-19x86: Add pci_init_irq to x86_initThomas Gleixner
Moorestown wants to reuse pcibios_init_irq but needs to provide its own implementation of pci_enable_irq. After we distangled the init we can move the init_irq call to x86_init and remove the pci_enable_irq != NULL check in pcibios_init_irq. pci_enable_irq is compile time initialized to pirq_enable_irq and the special cases which override it (visws and acpi) set the x86_init function pointer to noop. That allows MSRT to override pci_enable_irq and otherwise run pcibios_init_irq unmodified.

2010-02-19x86: Move pci init function to x86_initThomas Gleixner
The PCI initialization in pci_subsys_init() is a mess. pci_numaq_init, pci_acpi_init, pci_visws_init and pci_legacy_init are called and each implementation checks and eventually modifies the global variable pcibios_scanned. x86_init functions allow us to do this more elegant. The pci.init function pointer is preset to pci_legacy_init. numaq, acpi and visws can modify the pointer in their early setup functions. The functions return 0 when they did the full initialization including bus scan. A non zero return value indicates that pci_legacy_init needs to be called either because the selected function failed or wants the generic bus scan in pci_legacy_init to happen (e.g. visws).

2010-02-19x86, setup: Don't skip mode setting for the standard VGA modesH. Peter Anvin
The code for setting standard VGA modes probes for the current mode, and skips the mode setting if the mode is 3 (color text 80x25) or 7 (mono text 80x25). Unfortunately, there are BIOSes, including the VMware BIOS, which report the previous mode if function 0F is queried while the screen is in a VESA mode, and of course, nothing can help a mode poked directly into the hardware. As such, the safe option is to set the mode anyway, and only query to see if we should be using mode 7 rather than mode 3. People who don't want any mode setting at all should probably use vga=0x0f04 (VIDEO_CURRENT_MODE). It's possible that should be the kernel default.

2010-02-19hw-breakpoint: Keep track of dr7 local enable bitsFrederic Weisbecker
When the user enables breakpoints through dr7, he can choose between "local" or "global" enable bits but given how linux is implemented, both have the same effect. That said we don't keep track how the user enabled the breakpoints so when the user requests the dr7 value, we only translate the "enabled" status using the global enabled bits. It means that if the user enabled a breakpoint using the local enabled bit, reading back dr7 will set the global bit and clear the local one. Apps like Wine expect a full dr7 POKEUSER/PEEKUSER match for emulated softwares that implement old reverse engineering protection schemes. We fix that by keeping track of the whole dr7 value given by the user in the thread structure to drop this bug. We'll think about something more proper later. This fixes a 2.6.32 - 2.6.33-x ptrace regression.

Before we had a generic breakpoint API, ptrace was accepting breakpoints on NULL address in x86. The new API refuse them, without given strong reasons. We need to follow the previous behaviour as some userspace apps like Wine need such NULL breakpoints to ensure old emulated software protections are still working.
