[PATCH] pci and yenta: pcibios_bus_to_resource

2005-08-05T04:32:46Z

In yenta_socket, we default to using the resource setting of the CardBus bridge. However, this is a PCI-bus-centric view of resources and thus needs to be converted to generic resources first. Therefore, add a call to pcibios_bus_to_resource() call in between. This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).

[PATCH] x86_64: Some cleanup in setup64.c

2005-07-29T04:45:58Z

Minor cleanup. Move things into their include files, remove obsolete includes, fix indentation, remove obsolete special cases etc. I also added the per cpu section to asm-generic/sections.h and fixed init/main.c to use it.

[PATCH] Add emergency_restart()

2005-07-26T21:35:41Z

When the kernel is working well and we want to restart cleanly kernel_restart is the function to use. But in many instances the kernel wants to reboot when thing are expected to be working very badly such as from panic or a software watchdog handler. This patch adds the function emergency_restart() so that callers can be clear what semantics they expect when calling restart. emergency_restart() is expected to be callable from interrupt context and possibly reliable in even more trying circumstances. This is an initial generic implementation for all architectures. Signed-off-by: Eric W. Biederman Signed-off-by: Linus Torvalds

[PATCH] kexec: vmlinux: fix physical addresses

2005-06-25T23:24:47Z

In vmlinux.lds.h the code is carefull to define every section so vmlinux properly reports the correct physical load address of code, as well as it's virtual address. The new SECURITY_INIT definition fails to follow that convention and and causes incorrect physical address to appear in the vmlinux if there are any security initcalls. This patch updates the SECURITY_INIT to follow the convention in the rest of the file. Signed-off-by: Eric Biederman Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] adjust per_cpu definition in non-SMP case

2005-06-23T16:45:28Z

Fix (in the architectures I'm actually building for) the UP definition of per_cpu so that the cpu specified may be any expression, not just an identifier or a suffix expression. Signed-off-by: Jan Beulich Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] x86/x86_64: pcibus_to_node

2005-06-23T16:45:08Z

Define pcibus_to_node to be able to figure out which NUMA node contains a given PCI device. This defines pcibus_to_node(bus) in include/linux/topology.h and adjusts the macros for i386 and x86_64 that already provided a way to determine the cpumask of a pci device. x86_64 was changed to not build an array of cpumasks anymore. Instead an array of nodes is build which can be used to generate the cpumask via node_to_cpumask. Signed-off-by: Christoph Lameter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] msync: check pte dirty earlier

2005-06-22T01:46:21Z

It's common practice to msync a large address range regularly, in which often only a few ptes have actually been dirtied since the previous pass. sync_pte_range then goes much faster if it tests whether pte is dirty before locating and accessing each struct page cacheline; and it is hardly slowed by ptep_clear_flush_dirty repeating that test in the opposite case, when every pte actually is dirty. But beware, s390's pte_dirty always says false, since its dirty bit is kept in the storage key, located via the struct page address. So skip this optimization in its case: use a pte_maybe_dirty macro which just says true if page_test_and_clear_dirty is implemented.

[PATCH] ppc32: platform-specific functions missing from kallsyms.

2005-05-05T23:36:31Z

The PPC32 kernel puts platform-specific functions into separate sections so that unneeded parts of it can be freed when we've booted and actually worked out what we're running on today. This makes kallsyms ignore those functions, because they're not between _[se]text or _[se]inittext. Rather than teaching kallsyms about the various pmac/chrp/etc sections, this patch adds '_[se]extratext' markers for kallsyms.

[PATCH] asm/signal.h unification

2005-05-04T14:33:15Z

New file - asm-generic/signal.h. Contains declarations of __sighandler_t, __sigrestore_t, SIG_DFL, SIG_IGN, SIG_ERR and default definitions of SIG_BLOCK, SIG_UNBLOCK and SIG_SETMASK. asm-*/signal.h switched to including it. The only exception is asm-parisc/signal.h that wants its own declaration of __sighandler_t; that one is left as-is. asm-ppc64/signal.h required one more thing - unlike everybody else it used __sigrestorer_t instead of usual __sigrestore_t. PPC64 switched to common spelling. Signed-off-by: Al Viro Signed-off-by: Linus Torvalds

[PATCH] consolidate SIGEV_PAD_SIZE

2005-05-01T15:59:08Z

Discussing with Matthew Wilcox some of his outstanding patches lead me to this patch (among others). The preamble in struct sigevent can be expressed independently of the architecture. Also use __ARCH_SI_PREAMBLE_SIZE on ia64. Signed-off-by: Stephen Rothwell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
