* exec: unify do_execve/compat_do_execve codeOleg Nesterov2011-04-093-251/+50
| | | | | | | | | | | | | | | | | | | | Add the appropriate members into struct user_arg_ptr and teach get_user_arg_ptr() to handle is_compat = T case correctly. This allows us to remove the compat_do_execve() code from fs/compat.c and reimplement compat_do_execve() as the trivial wrapper on top of do_execve_common(is_compat => true). In fact, this fixes another (minor) bug. "compat_uptr_t str" can overflow after "str += len" in compat_copy_strings() if a 64bit application execs via sys32_execve(). Unexport acct_arg_size() and get_arg_page(), fs/compat.c doesn't need them any longer.

* exec: introduce struct user_arg_ptrOleg Nesterov2011-04-091-12/+30
| | | | | | | | | | | | | | | No functional changes, preparation. Introduce struct user_arg_ptr, change do_execve() paths to use it instead of "char __user * const __user *argv". This makes the argv/envp arguments opaque, we are ready to handle the compat case which needs argv pointing to compat_uptr_t.

| | | | | | | | | | | | Introduce get_user_arg_ptr() helper, convert count() and copy_strings() to use it. No functional changes, preparation. This helper is trivial, it just reads the pointer from argv/envp user-space array.

| * [S390] compile fix for latest binutilsMartin Schwidefsky2011-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | The latest binutils won't accept the stfl instruction with march=g5 which is the correct behaviour. Unfortunately head.S is assembled with -march=g5 even if the target cpu is z900 or later. To get 31-bit kernels compiled again the easiest fix is to use the .insn notation for the stfl instruction in head.S. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
| * [S390] cio: prevent purging of CCW devices in the online statePeter Oberparleiter2011-04-041-6/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cio_ignore purge function is intended to only remove CCW devices which are in the offline state. There is a time frame after the purge function finished where a CCW device is scheduled for removal but still accessible. When the device is set online during this time frame, it may first appear online before it is then removed. Fix this by preventing that CCW devices can be set online while there is work (such as removal triggered by the purge function) for it pending. Also ensure that the purge function does not schedule devices for removal which are in the process of being set online.

| | | | | | | | | | | | | | | | | | | | | | After the execution has been switched to the destination CPU, the target function is called with the wrong parameter. According to the C calling convention on s390, the first parameter should be loaded into register 2. Currently in smp_restart_cpu() it is stored in register 3. To fix this, we load the parameter into the correct register 2. Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| * | quota: Don't write quota info in dquot_commit()Jan Kara2011-04-011-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no reason to write quota info in dquot_commit(). The writing is a relict from the old days when we didn't have dquot_acquire() and dquot_release() and thus dquot_commit() could have created / removed quota structures from the file. These days dquot_commit() only updates usage counters / limits in quota structure and thus there's no need to write quota info. This also fixes an issue with journaling filesystem which didn't reserve enough space in the transaction for write of quota info (it could have been dirty at the time of dquot_commit() because of a race with other operation changing it).

Without this parameter, sci_console_init is called during early console setup without any port being initialized, and the kernel crashes a little bit later when uart_set_options attemps to invoke set_termios on a port with an ops member equal to NULL. This patch just checks in sci_console_init that the port is properly initialized, and aborts the early console setup if it is not.

This patch updates find_perf_probe_point() and introduces new rules to get correct line number. - If debuginfo doesn't have a correct file name, we shouldn't return line number too, because, without file name, line number is meaningless. - If the address is in a function, it stores the function name and the offset from the function entry. - If the address is on a line, it tries to get the relative line number from the function entry line, except for the address is same as the entry address of the function (in this case, the relative line number should be 0). - If the address is in an inline function entry (call-site), it uses the inline function call line number as the line on which the address is. - If the address is in an inline function body, it stores the inline function name and offset from the inline function call site instead of the (non-inlined) function.
