* s390: remove 31 bit syscallsHeiko Carstens2015-03-251-358/+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>

* s390/compat: get rid of compat wrapper assembly codeHeiko Carstens2014-03-061-62/+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>
* s390/compat: add sync_file_range and fallocate compat syscallsHeiko Carstens2014-03-041-2/+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.

* s390/compat: convert system call wrappers to C part 01Heiko Carstens2014-03-041-12/+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.

* s390: add support for runtime instrumentationJan Glauber2012-09-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow user-space threads to use runtime instrumentation (RI). To enable RI for a thread there is a new s390 specific system call, sys_s390_runtime_instr, that takes as parameter a realtime signal number. If the RI facility is available the system call sets up a control block for the calling thread with the appropriate permissions for the thread to modify the control block. The user-space thread can then use the store and modify RI instructions to alter the control block and start/stop the instrumentation via RION/RIOFF. If the user specified program buffer runs full RI triggers an external interrupt. The external interrupt is translated to a real-time signal that is delivered to the thread that enabled RI on that CPU. The number of the real-time signal is the number specified in the RI system call. So, user-space can select any available real-time signal number in case the application itself uses real-time signals for other purposes. The kernel saves the RI control blocks on task switch only if the running thread was enabled for RI. Therefore, the performance impact on task switch should be negligible if RI is not used. RI is only enabled for user-space mode and is disabled for the supervisor state.
