* [ARM] Remove unused DYN_TICK_* macrosRussell King2005-09-05
| | | | | | | Neither DYN_TICK_SKIPPING nor DYN_TICK_SUITABLE are used on ARM. Remove them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Wrap calls to descriptor handlersRussell King2005-09-04
| | | | | | | | | | This is part of Thomas Gleixner's generic IRQ patch, which converts ARM to use the generic IRQ subsystem. Here, we wrap calls to desc->handler() in an inline function, desc_handle_irq(). This reduces the size of Thomas' patch since the changes become more localised.

| | | | | | | | This is part of Thomas Gleixner's generic IRQ patch, which converts ARM to use the generic IRQ subsystem. Here, we rename two of the irq_chip methods - wake becomes set_wake, and type becomes set_type. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * [ARM] 2865/2: fix fadvise64_64 syscall argument passingNicolas Pitre2005-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Nicolas Pitre The prototype for sys_fadvise64_64() is: long sys_fadvise64_64(int fd, loff_t offset, loff_t len, int advice) The argument list is therefore as follows on legacy ABI: fd: type int (r0) offset: type long long (r1-r2) len: type long long (r3-sp[0]) advice: type int (sp[4]) With EABI this becomes: fd: type int (r0) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) advice: type int (sp[8]) Not only do we have ABI differences here, but the EABI version requires one additional word on the syscall stack. To avoid the ABI mismatch and the extra stack space required with EABI this syscall is now defined with a different argument ordering on ARM as follows: long sys_arm_fadvise64_64(int fd, int advice, loff_t offset, loff_t len) This gives us the following ABI independent argument distribution: fd: type int (r0) advice: type int (r1) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) Now, since the syscall entry code takes care of 5 registers only by default including the store of r4 to the stack, we need a wrapper to store r5 to the stack as well. Because that wrapper was missing and was always required this means that sys_fadvise64_64 never worked on ARM and therefore we can safely reuse its syscall number for our new sys_arm_fadvise64_64 interface.

* [ARM] Control v6 'global' bit via Linux PTE entriesRussell King2005-08-10

* [PATCH] pci and yenta: pcibios_bus_to_resourceDominik Brodowski2005-08-05
| | | | | | | | | | | | | | | 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] Add emergency_restart()Eric W. Biederman2005-07-26
|/ | | | | | | | | | | | | | | | | | 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 <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Deepak Saxena This patch implements the iomap API for Intel IXP4xx NPU systems. We need to implement our own version of the API functions b/c of the PCI hostbridge does not provide the capability to map PCI I/O space into the CPU's physical memory space. In addition, if a system has more than 64M of PCI memory mapped BARs, PCI memory must also be accessed indirectly. This patch changes the assignment of PCI I/O resources to fall into to 0x0000:0xffff range so that we can trap I/O areas in our ioread/iowrite macros.
