2015-09-18s390: wire up separate socketcalls system callsHeiko Carstens1-0/+17
As discussed on linux-arch all architectures should wire up the separate system calls that are hidden behind the socketcall multiplexer system call. It's just a couple more system calls and gives us a very small performance improvement.

2015-09-18s390/compat: remove superfluous compat wrappersHeiko Carstens1-51/+51
A couple of compat wrapper functions are simply trampolines to the real system call. This happened because the compat wrapper defines will only sign and zero extend system call parameters which are of different size on s390/s390x (longs and pointers). All other parameters will be correctly sign and zero extended by the normal system call wrappers.

2015-08-03s390/numa: add core infrastructurePhilipp Hachtmann1-5/+5
Enable core NUMA support for s390 and add one simple default mode "plain" that creates one single NUMA node. This patch contains several changes from Michael Holzheu.

2015-03-25s390: remove 31 bit syscallsHeiko Carstens1-358/+358
Remove the 31 bit syscalls from the syscall table. This is a separate patch just in case I screwed something up so it can be easily reverted. However the conversion was done with a script, so everything should be ok. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2014-11-19s390/kernel: add system calls for PCI memory accessAlexey Ishchuk1-0/+2
Add the new __NR_s390_pci_mmio_write and __NR_s390_pci_mmio_read system calls to allow user space applications to access device PCI I/O memory pages on s390x platform.

2014-03-06s390/compat: get rid of compat wrapper assembly codeHeiko Carstens1-62/+62
Now that all compat syscalls have been converted to use the COMPAT_SYSCALL_DEFINE macros, we don't need to compat syscall wrapper assembly code anymore. So remove it and fix up the system call table accordingly. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2014-03-04s390/compat: add sync_file_range and fallocate compat syscallsHeiko Carstens1-2/+2
The compat syscall wrappers for sync_file_range and fallocate merged 32 bit parameters into 64 bit parameters. Therefore they did more than just the usual zero and/or sign extension of system call parameters. So convert these two wrappers to full s390 specific compat sytem calls.

2014-03-04s390/compat: convert system call wrappers to C part 01Heiko Carstens1-12/+12
Introduce a new compat_wrap.c file which contains the s390 specific compat system call wrappers. The s390 specific system call wrappers only perform sign, zero and pointer conversion of system call arguments before actually calling the non-compat system call. Therefore introduce COMPAT_SYSCALL_WRAPx macros which generate C code that is nearly identical to the assembly code. This has the advantage that the compile will generate correct code, and we avoid the frequent copy-paste errors seen in the compat_wrapper.S file.
