BKL: remove extraneous #include

2010-11-17T16:59:32+00:00

The big kernel lock has been removed from all these files at some point,
leaving only the #include.

Remove this too as a cleanup.

Make do_execve() take a const filename pointer

2010-08-18T01:07:43+00:00

Make do_execve() take a const filename pointer so that kernel_execve() compiles
correctly on ARM:

arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type

This also requires the argv and envp arguments to be consted twice, once for
the pointer array and once for the strings the array points to.  This is
because do_execve() passes a pointer to the filename (now const) to
copy_strings_kernel().  A simpler alternative would be to cast the filename
pointer in do_execve() when it's passed to copy_strings_kernel().

do_execve() may not change any of the strings it is passed as part of the argv
or envp lists as they are some of them in .rodata, so marking these strings as
const should be fine.

Further kernel_execve() and sys_execve() need to be changed to match.

This has been test built on x86_64, frv, arm and mips.

Mark arguments to certain syscalls as being const

2010-08-13T23:53:13+00:00

Mark arguments to certain system calls as being const where they should be but
aren't.  The list includes:

 (*) The filename arguments of various stat syscalls, execve(), various utimes
     syscalls and some mount syscalls.

 (*) The filename arguments of some syscall helpers relating to the above.

 (*) The buffer argument of various write syscalls.

frv: Remove the BKL from sys_execve

2009-10-14T15:18:14+00:00

sys_execve for frv seems to be a copy-and-paste of sys_execve that no
longer requires the bkl. Just remove it.

[PATCH] FRV: Fix FRV arch compile errors

2006-07-10T20:24:21+00:00

Fix some FRV arch compile errors, including:

 (*) Marking nr_kernel_pages as __meminitdata so that references to it end up
     being properly calculated rather than being assumed to be in the small
     data section (and thus calculated wrt the GP register).  Not doing this
     causes the linker to emit errors as the offset is too big to fit into the
     load instruction.

 (*) Move pm_power_off into an unconditionally compiled .c file as it's now
     unconditionally accessed.

 (*) Declare frv_change_cmode() in a header file rather than in a .c file, and
     declare it asmlinkage.
