We are currently only reporting syspect indents if the conditional is
modified but the indent missmatch could be generated by the body changing,
make sure we catch both. Also only report the first line of the body, and
more importantly make sure we report the raw copy of the line. Finally
report the indent levels to make it easier to understand what is wrong.

This series of patches re-introduces the iommu_num_pages function so that
it can be used by each architecture specific IOMMU implementations. The
series also changes IOMMU implementations for X86, Alpha, PowerPC and
UltraSparc. The other implementations are not yet changed because the
modifications required are not obvious and I can't test them on real
hardware.

struct stat / compat_stat is the same on all architectures, so
cp_compat_stat should be, too.
Turns out it is, except that various architectures have slightly and some
high2lowuid/high2lowgid or the direct assignment instead of the
SET_UID/SET_GID that expands to the correct one anyway.
This patch replaces the arch-specific cp_compat_stat implementations with
a common one based on the x86-64 one.

Thomas found that there is an unnecessary (always true) test in
ep_send_events(). The callback never inserts into ->rdllink while the
send loop is performed, and also does the ~EP_PRIVATE_BITS test. Given
we're holding the mutex during this time, the conditions tested inside the
loop are always true. This patch drops the test done inside the
re-insertion loop.

With MAX_ARG_STRINGS set to 0x7FFFFFFF, and being passed to 'count()' and
compat_count(), it would appear that the current max bounds check of
fs/exec.c:394:
if(++i > max)
return -E2BIG;
would never trigger. Since 'i' is of type int, so values would wrap and the
function would continue looping.
Simple fix seems to be chaning ++i to i++ and checking for '>='.

On sethostname() and setdomainname(), previous information may be retained
if it was longer than than the new hostname/domainname.
This can be demonstrated trivially by calling sethostname() first with a
long name, then with a short name, and then calling uname() to retrieve
the full buffer that contains the hostname (and possibly parts of the old
hostname), one just has to look past the terminating zero.
I don't know if we should really care that much (hence the RFC); the only
scenarios I can possibly think of is administrator putting something
sensitive in the hostname (or domain name) by accident, and changing it
back will not undo the mistake entirely, though it's not like we can
recover gracefully from "rm -rf /" either... The other scenario is
namespaces (CLONE_NEWUTS) where some information may be unintentionally
"inherited" from the previous namespace (a program wants to hide the
original name and does clone + sethostname, but some information is still
left).
I think the patch may be defended on grounds of the principle of least
surprise. But I am not adamant :-)
(I guess the question now is whether userspace should be able to
write embedded NULs into the buffer or not...)
At least the observation has been made and the patch has been presented.
