mm, show_mem: suppress page counts in non-blockable contexts

2013-10-26T20:06:13+00:00

commit 4b59e6c4730978679b414a8da61514a2518da512 upstream.

On large systems with a lot of memory, walking all RAM to determine page
types may take a half second or even more.

In non-blockable contexts, the page allocator will emit a page allocation
failure warning unless __GFP_NOWARN is specified.  In such contexts, irqs
are typically disabled and such a lengthy delay may even result in NMI
watchdog timeouts.

To fix this, suppress the page walk in such contexts when printing the
page allocation failure warning.

unicore32, exec: remove redundant set_fs(USER_DS)

2011-11-16T02:50:09+00:00

The address limit is already set in flush_old_exec() so this
set_fs(USER_DS) is redundant.

arch/unicore32: do not use EXTRA_AFLAGS or EXTRA_CFLAGS

2011-11-15T09:13:15+00:00

Usage of these flags has been deprecated for nearly 4 years by:

    commit f77bf01425b11947eeb3b5b54685212c302741b8
    Author: Sam Ravnborg 
    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

doc: fix broken references

2011-09-27T16:08:04+00:00

There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.

Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

This patch removes all the module loader hook implementations in the
architecture specific code where the functionality is the same as that
now provided by the recently added default hooks.
