The previous checkstack fix for UML, which needs to use the host's tools,
was wrong in the crossbuilding case. It would use the build host's, rather
than the target's, toolchain.
This patch removes the old fix and adds an explicit special case for UML,
leaving everyone else alone.

Fallback_alloc() does not do the check for GFP_WAIT as done in
cache_grow(). Thus interrupts are disabled when we call kmem_getpages()
which results in the failure.

Fields of struct pipe_buf_operations have not a precise layout (ie not
optimized to fit cache lines nor reduce cache line ping pongs)
The bufs[] array is *large* and is placed near the beginning of the
structure, so all following fields have a large offset. This is
unfortunate because many archs have smaller instructions when using small
offsets relative to a base register. On x86 for example, 7 bits offsets
have smaller instruction lengths.
Moving bufs[] at the end of pipe_buf_operations permits all fields to have
small offsets, and reduce text size, and icache pressure.
# size vmlinux.pre vmlinux
text data bss dec hex filename
3268989 664356 492196 4425541 438745 vmlinux.pre
3268765 664356 492196 4425317 438665 vmlinux
So this patch reduces text size by 224 bytes on my x86_64 machine. Similar
results on ia32.

Those two functions are
void sym_set_change_count(int count)
and
void sym_add_change_count(int count)
All write accesses to sym_change_count are replaced by calls to above
functions.
Variable and changer-functions are moved to confdata.c. IMO thats ok, as
sym_change_count is an attribute of the .config's change state.

Run "make xconfig" on a freshly untarred kernel-tree. Look at the floppy disk
icon of the qt application, that has just started: Its in a normal, active
state.
Mouse click on it: .config is being saved.
This patch series changes things so taht
after the mouse click on the floppy disk icon, the icon is greyed out.
If you mouse click on it now, nothing happens.
If you change some CONFIG_*, the floppy disk icon returns to "active state",
that is, if you mouse click it now, .config is written.
This patch:
Returns sym_change_count to reflect the .config's change state.
All read only accesses of
sym_change_count
are replaced by calls to
conf_get_changed()
.
mconfig.c is manipulated to ask for saving only when
conf_get_changed() returned true.

This reverts commit 373beb35cd.
No one is using this identifier yet. The purpose of this identifier is to
export nsproxy to user space which is wrong. nsproxy is an internal
implementation optimization, which should keep our fork times from getting
slower as we increase the number of global namespaces you don't have to
share.
Adding a global identifier like this is inappropriate because it makes
namespaces inherently non-recursive, greatly limiting what we can do with
them in the future.

This patch removes calls to pci_disable_device except in fail_all_cmds. The

Also, customers can disable any pci device via the ROM Based Setup Utility

blindly enable the card from the driver. Please consider this for inclusion.
