* s390/compat: get rid of compat wrapper assembly codeHeiko Carstens2014-03-061-369/+0
| | | | | | | | | 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 Carstens2014-03-041-18/+0
| | | | | | | | | | 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 Carstens2014-03-041-56/+0
| | | | | | | | | | | | | | | 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.

* open*(2) compat fixes (s390, arm64)Al Viro2012-12-021-1/+1
| | | | | | | | | | | | | | | | | | | The usual rules for open()/openat()/open_by_handle_at() are 1) native 32bit - don't force O_LARGEFILE in flags 2) native 64bit - force O_LARGEFILE in flags 3) compat on 64bit host - as for native 32bit 4) native 32bit ABI for 64bit system (mips/n32, x86/x32) - as for native 64bit There are only two exceptions - s390 compat has open() forcing O_LARGEFILE and arm64 compat has open_by_handle_at() doing the same thing. The same binaries on native host (s390/31 and arm resp.) will *not* force O_LARGEFILE, so IMO both are emulation bugs. Objections? The fix is obvious...
