https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-3.15.y2014-03-04T08:05:47Zs390/compat: add sync_file_range and fallocate compat syscalls2014-03-04T08:05:47ZHeiko Carstens2014-03-01T12:09:26Zurn:sha1:2c81fc4fb41f589454861bbdb90ffde73840b8f8
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.

Convert s390 specific system calls to to the new COMPAT_SYSCALL_DEFINE macro.
This allows us to get rid of the assembly compat wrappers.

s390/compat: change parameter types from unsigned long to compat_ulong_t2014-01-30T00:22:40ZHeiko Carstens2014-01-29T22:05:47Zurn:sha1:49382d93852f1ba4a4fbbce20d094f600cc8aff8
Change parameter types of s390's compat ipc syscall from unsigned long
to compat_ulong_t to enforce zero extension of these parameters.
This is not really a bug, since s390_ipc compat syscall is only a
wrapper to the generic compat_sys_ipc() syscall, which performs correct
zero and sign extension.
This was introduced with commit 56e41d3c5aa8 ("merge compat sys_ipc
instances").

s390/compat: make psw32_user_bits a constant value again2013-10-24T15:17:12ZHeiko Carstens2013-10-16T12:17:29Zurn:sha1:f26946d7ecad0afdd85e6ae56663d0fe26676b34
Make psw32_user_bits a constant value again.
This is a leftover of the code which allowed to run the kernel either
in primary or home space which got removed with 9a905662 "s390/uaccess:
always run the kernel in home space".
