kbuild: rename built-in.o to built-in.a

2018-03-25T17:01:19+00:00

Incremental linking is gone, so rename built-in.o to built-in.a, which is the usual extension for archive files. This patch does two things, first is a simple search/replace: git grep -l 'built-in\.o' | xargs sed -i 's/built-in\.o/built-in\.a/g' The second is to invert nesting of nested text manipulations to avoid filtering built-in.a out from libs-y2: -libs-y2 := $(filter-out %.a, $(patsubst %/, %/built-in.a, $(libs-y))) +libs-y2 := $(patsubst %/, %/built-in.a, $(filter-out %.a, $(libs-y))) Signed-off-by: Nicholas Piggin Signed-off-by: Masahiro Yamada

s390: add a few more SPDX identifiers

2017-12-05T06:51:09+00:00

Add the correct SPDX license to a few more files under arch/s390 and drivers/s390 which have been missed to far. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. Signed-off-by: Martin Schwidefsky

virtio/s390: rename drivers/s390/kvm -> drivers/s390/virtio

2015-07-07T11:27:06+00:00

This more accurately reflects what these drivers actually do. Suggested-by: Paolo Bonzini Acked-by: Christian Borntraeger Signed-off-by: Cornelia Huck Signed-off-by: Michael S. Tsirkin

[S390] split/move machine check handler code

2009-03-26T14:24:10+00:00

Split machine check handler code and move it to cio and kernel code where it belongs to. No functional change. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] move sysinfo.c from drivers/s390 to arch/s390/kernel

2009-03-26T14:24:06+00:00

All in sysinfo.c is core kernel code and not driver code. So move it to arch/s390/kernel. Also includes some small cleanups. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

s390: KVM guest: virtio device support, and kvm hypercalls

2008-04-27T09:00:51+00:00

This patch implements kvm guest kernel support for paravirtualized devices and contains two parts: o a basic virtio stub using virtio_ring and external interrupts and hypercalls o full hypercall implementation in kvm_para.h Currently we dont have PCI on s390. Making virtio_pci usable for s390 seems more complicated that providing an own stub. This virtio stub is similar to the lguest one, the memory for the descriptors and the device detection is made via additional mapped memory on top of the guest storage. We use an external interrupt with extint code 0x2603 for host->guest notification. The hypercall definition uses the diag instruction for issuing a hypercall. The parameters are written in R2-R7, the hypercall number is written in R1. This is similar to the system call ABI (svc) which can use R1 for the number and R2-R6 for the parameters.

[S390] Calibrate delay and bogomips.

2007-02-05T20:18:31+00:00

Preset the bogomips number to the cpu capacity value reported by store system information in SYSIB 1.2.2. This value is constant for a particular machine model and can be used to determine relative performance differences between machines. Signed-off-by: Martin Schwidefsky

[PATCH] s390: move s390_root_dev_* out of the cio layer

2006-01-06T16:33:49+00:00

Extract the s390_root_dev_* functions from the common I/O layer as they are also used by non-ccw device drivers. Signed-off-by: Carsten Otte Signed-off-by: Martin Schwidefsky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
