alpha: nautilus - fix compile failure with gcc-4.3

2009-02-02T16:28:08+00:00

commit 70b66cbfd3316b792a855cb9a2574e85f1a63d0f upstream.

init_srm_irq() deals with irq's #16 and above, but size of irq_desc
array on nautilus and some other system types is 16. So gcc-4.3
complains that "array subscript is above array bounds", even though
this function is never called on those systems.

This adds a check for NR_IRQS <= 16, which effectively optimizes
init_srm_irq() code away on problematic platforms.

Thanks to Daniel Drake  for detailed analysis
of the problem.

Remove attribute((weak)) from sys_pipe/sys_pipe2

2009-01-18T18:35:33+00:00

commit 1134723e96f6e2abcf8bfd7a2d1c96fcc323ef35 upstream.

Remove __attribute__((weak)) from common code sys_pipe implemantation.
IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations
with the same name. Just rename them.
For sys_pipe2 there is no architecture specific implementation.

[PATCH] fix osf_getdirents()

2008-08-25T05:18:06+00:00

Return value of filldir callback is just "should we stop here"; it's
not a usable channel for passing error values (i.e. ->readdir() will
forget anything except "is it non-zero").

[PATCH] sanitize __user_walk_fd() et.al.

2008-07-27T00:53:34+00:00

* do not pass nameidata; struct path is all the callers want.
* switch to new helpers:
	user_path_at(dfd, pathname, flags, &path)
	user_path(pathname, &path)
	user_lpath(pathname, &path)
	user_path_dir(pathname, &path)  (fail if not a directory)
  The last 3 are trivial macro wrappers for the first one.
* remove nameidata in callers.

Alpha Linux kernel fails with inconsistent kallsyms data

2008-07-04T17:40:09+00:00

The build of the Alpha Linux kernel currently fails[1] with inconsistent
kallsyms data.  As I never saw that before, I thought about hardware
problems.  But in fact it is a bug in the Linux kernel.

The end of the rodata section is marked with the "__end_rodata" symbol.
This symbol have different aligning constraints than the inittext parts
and therefor the start marked "_sinittext".  Because of that the
__end_rodata symbol shifts between < _sinittext and == _sinittext.  The
later variant is seen as a code symbol and recorded in the kallsyms data.

On fix would be to move the exception table a little bit and get some
space between that two areas.

on_each_cpu(): kill unused 'retry' parameter

2008-06-26T09:24:38+00:00

It's not even passed on to smp_call_function() anymore, since that
was removed. So kill it.

smp_call_function: get rid of the unused nonatomic/retry argument

2008-06-26T09:24:35+00:00

It's never used and the comments refer to nonatomic and retry
interchangably. So get rid of it.

alpha: convert to generic helpers for IPI function calls

2008-06-26T09:22:57+00:00

This converts alpha to use the new helpers for smp_call_function() and
friends, and adds support for smp_call_function_single().
