Make "install_page()" able to handle truncated pages.
This makes it much easier on the callers, no need to
worry about races with vmtruncate() and friends, since
"install_page()" will just cleanly handle that case
and tell the caller about it.

[PATCH] clean up n_tty alloc_buf()
Don't bother zeroing the allocated memory inside alloc_buf() in the
n_tty line discipline. alloc_buf() is static inline and is only
referenced by n_tty_open() which always clears the memory (once more).
No bug, just a minor cleanup

The recent changes to (6 Jul 04) pkt_cls.h are evil, you can't build a version
of 'tc' to work unless you know the kernel config!
It has several API problems:
- API data structures change on kernel config options
- new fields should be added at the end of a structure to allow
binary compatibility.

[INET]: Create enum of ECN bits
This patch is a preparation for an update of the ECN encap/decap
code with respect to RFC3168.
It creates an enum of the four code-points defined by RFC3168
and uses them throughout the inet_ecn.h file.
The only non-trivial bit is in IP_ECN_set_ce/IP6_ECN_set_ce where
the patch uses INET_ECN_CE instead of 1. This is OK as those
functions assume that the ECT bit is already set.

[CRYPTO]: Fix stack overrun in crypt().
The stack allocation in crypt() is bogus as whether tmp_src/tmp_dst
is used is determined by factors unrelated to nbytes and
src->length/dst->length.
Since the condition for whether tmp_src/tmp_dst are used is very
complex, let's allocate them always instead of guessing.
This fixes a number of weird crashes including those AES crashes
that people have been seeing with the 2.4 backport + ipt_conntrack.

[PATCH] NX: clean up legacy binary support
This cleans up legacy x86 binary support by introducing a new
personality bit: READ_IMPLIES_EXEC, and implements Linus' suggestion to
add the PROT_EXEC bit on the two affected syscall entry places,
sys_mprotect() and sys_mmap(). If this bit is set then PROT_READ will
also add the PROT_EXEC bit - as expected by legacy x86 binaries. The
ELF loader will automatically set this bit when it encounters a legacy
binary.
This approach avoids the problems the previous ->def_flags solution
caused. In particular this patch fixes the PROT_NONE problem in a
cleaner way (http://lkml.org/lkml/2004/7/12/227), and it should fix the
ia64 PROT_EXEC problem reported by David Mosberger. Also,
mprotect(PROT_READ) done by legacy binaries will do the right thing as
well.
the details:
- the personality bit is added to the personality mask upon exec(),
within the ELF loader, but is not cleared (see the exceptions below).
This means that if an environment that already has the bit exec()s a
new-style binary it will still get the old behavior.
- one exception are setuid/setgid binaries: these will reset the
bit - thus local attackers cannot manually set the bit and circumvent
NX protection. Legacy setuid binaries will still get the bit through
the ELF loader. This gives us maximum flexibility in shaping
compatibility environments.
- selinux also clears the bit when switching SIDs via exec().
- x86 is the only arch making use of READ_IMPLIES_EXEC currently. Other
arches will have the pre-NX-patch protection setup they always had.
I have booted an old distro [RH 7.2] and two new PT_GNU_STACK distros
[SuSE 9.2 and FC2] on an NX-capable CPU - they work just fine and all
the mapping details are right. I've checked the PROT_NONE test-utility
as well and it works as expected. I have checked various setuid
scenarios as well involving legacy and new-style binaries.
an improved setarch utility can be used to set the personality bit
manually:
http://redhat.com/~mingo/nx-patches/setarch-1.4-3.tar.gz
the new '-X' flag does it, e.g.:
./setarch -X linux /bin/cat /proc/self/maps
will trigger the old protection layout even on a new distro.

[PATCH] pmac_zilog: serial minors taken failure path fix
I've tracked down the core issue giving me the oops wrt pmac_zilog.
When you have two serial drivers, (e.g. 8250 and PMAC_ZILOG) they both say
"I want to reserve X ports starting with major TTY_MAJOR and minor 64".
By the time pmac_zilog gets there, the ports it requests are already
reserved. Unfortunately, init_pmz() doesn't check for pmz_register()
failure, and so it merrily goes on to register the half-initialized
pmac_zilog driver with the power management subsystem.
This path provides a proper failure path.
Also:
Restore ppc configs now that I know people use AT Keyboards on CHRP and PReP
machines, and the zilog driver is no longer Oops'ing.
