alpha: take a bunch of syscalls into osf_sys.c

2012-08-19T15:41:19Z

New helper: current_thread_info(). Allows to do a bunch of odd syscalls in C. While we are at it, there had never been a reason to do osf_getpriority() in assembler. We also get "namespace"-aware (read: consistent with getuid(2), etc.) behaviour from getx?id() syscalls now.

alpha: Use new generic strncpy_from_user() and strnlen_user()

2012-08-19T15:41:18Z

Similar to x86/sparc/powerpc implementations except: 1) we implement an extremely efficient has_zero()/find_zero() sequence with both prep_zero_mask() and create_zero_mask() no-operations. 2) Our output from prep_zero_mask() differs in that only the lowest eight bits are used to represent the zero bytes nevertheless it can be safely ORed with other similar masks from prep_zero_mask() and forms input to create_zero_mask(), the two fundamental properties prep_zero_mask() must satisfy. Tests on EV67 and EV68 CPUs revealed that the generic code is essentially as fast (to within 0.5% of CPU cycles) of the old Alpha specific code for large quadword-aligned strings, despite the 30% extra CPU instructions executed. In contrast, the generic code for unaligned strings is substantially slower (by more than a factor of 3) than the old Alpha specific code.

alpha: remove mysterious if zero-ed out includes

2012-07-31T00:25:11Z

There's a small group of odd looking includes in smc37c669.c. These includes appear to be if zero-ed out ever since they were added to the tree (in v2.1.89). Their purpose is unclear to me. Perhaps they were used in someones build system. Whatever their purpose was, nothing else uses something comparable. This entire if zero-ed out block might as well be removed.

alpha/PCI: factor out pcibios_setup()

2012-06-26T12:54:28Z

The PCI core provides a generic pcibios_setup() routine. Drop this architecture-specific version in favor of that. Acked-by: Richard Henderson Signed-off-by: Myron Stowe Signed-off-by: Bjorn Helgaas

PCI: replace struct pci_bus secondary/subordinate with busn_res

2012-06-13T21:42:22Z

Replace the struct pci_bus secondary/subordinate members with the struct resource busn_res. Later we'll build a resource tree of these bus numbers. [bhelgaas: changelog] Signed-off-by: Yinghai Lu Signed-off-by: Bjorn Helgaas

alpha/PCI: move fixup hooks from init to devinit

2012-06-12T15:10:54Z

The fixups are executed once the pci-device is found which is during boot process so __init seems fine as long as the platform does not support hotplug. However it is possible to remove the PCI bus at run time and have it rediscovered again via "echo 1 > /sys/bus/pci/rescan" and this will call the fixups again.
