There's a bunch of code that compares an address with KERNELBASE to see if
it's a "kernel address", ie. >= KERNELBASE. The proper test is actually to
compare with PAGE_OFFSET, since we're going to change KERNELBASE soon.
So replace all of them with an is_kernel_addr() macro that does that.

3) Allows m8xx_wdt to use a kernel timer instead of the builtin RTC/PIT

until an userspace application takes over). For instance Cyclades PRxK
boards (MPC 855T based) have a non-functional internal RTC/PIT unit.
Behaviour for boards with RTC/PIT is unchaged.
4) The last change required moving the RTCSC register setting code
to a weak function which can be overriden by board specific files.
Otherwise the timer init code trashes the register making it impossible

[PATCH] syscall entry/exit revamp
This cleanup patch speeds up the null syscall path on ppc64 by about 3%,
and brings the ppc32 and ppc64 code slightly closer together.
The ppc64 code was checking current_thread_info()->flags twice in the
syscall exit path; once for TIF_SYSCALL_T_OR_A before disabling
interrupts, and then again for TIF_SIGPENDING|TIF_NEED_RESCHED etc after
disabling interrupts. Now we do the same as ppc32 -- check the flags
only once in the fast path, and re-enable interrupts if necessary in the
ptrace case.
The patch abolishes the 'syscall_noerror' member of struct thread_info
and replaces it with a TIF_NOERROR bit in the flags, which is handled in
the slow path. This shortens the syscall entry code, which no longer
needs to clear syscall_noerror.
The patch adds a TIF_SAVE_NVGPRS flag which causes the syscall exit slow
path to save the non-volatile GPRs into a signal frame. This removes the
need for the assembly wrappers around sys_sigsuspend(),
sys_rt_sigsuspend(), et al which existed solely to save those registers
in advance. It also means I don't have to add new wrappers for ppoll()
and pselect(), which is what I was supposed to be doing when I got
distracted into this...
Finally, it unifies the ppc64 and ppc32 methods of handling syscall exit
directly into a signal handler (as required by sigsuspend et al) by
introducing a TIF_RESTOREALL flag which causes _all_ the registers to be
reloaded from the pt_regs by taking the ret_from_exception path, instead
of the normal syscall exit path which stomps on the callee-saved GPRs.
It appears to pass an LTP test run on ppc64, and passes basic testing on
ppc32 too. Brief tests of ptrace functionality with strace and gdb also
appear OK. I wouldn't send it to Linus for 2.6.15 just yet though :)

[PATCH] powerpc: Merge kexec
This patch merges, to some extent, the PPC32 and PPC64 kexec implementations.
We adopt the PPC32 approach of having ppc_md callbacks for the kexec functions.
The current PPC64 implementation becomes the "default" implementation for PPC64
which platforms can select if they need no special treatment.
I've added these default callbacks to pseries/maple/cell/powermac, this means
iSeries no longer supports kexec - but it never worked anyway.
I've renamed PPC32's machine_kexec_simple to default_machine_kexec, inline with
PPC64. Judging by the comments it might be better named machine_kexec_non_of,
or something, but at the moment it's the only implementation for PPC32 so it's
the "default".
Kexec requires machine_shutdown(), which is in machine_kexec.c on PPC32, but we
already have in setup-common.c on powerpc. All this does is call
ppc_md.nvram_sync, which only powermac implements, so instead make
machine_shutdown a ppc_md member and have it call core99_nvram_sync directly
on powermac.
I've also stuck relocate_kernel.S into misc_32.S for powerpc.
Built for ARCH=ppc, and 32 & 64 bit ARCH=powerpc, with KEXEC=y/n. Booted on
P5 LPAR and successfully kexec'ed.

Nothing prevents a user to modprobe a framebuffer driver from e.g. the

This is fatal as a lot of X / framebuffer combinations are unable to

It is also unnecessary as the set_par() function will be called during a

[PATCH] Fix posix-cpu-timers sched_time accumulation
I've spent the past 3 days digging into a glibc testsuite failure in
current CVS, specifically libc/rt/tst-cputimer1.c The thr1 and thr2
timers fire too early in the second pass of this test. The second
pass is noteworthy because it makes use of intervals, whereas the
first pass does not.
All throughout the posix-cpu-timers.c code, the calculation of the
process sched_time sum is implemented roughly as:
unsigned long long sum;
sum = tsk->signal->sched_time;
t = tsk;
do {
sum += t->sched_time;
t = next_thread(t);
} while (t != tsk);
In fact this is the exact scheme used by check_process_timers().
In the case of check_process_timers(), current->sched_time has just
been updated (via scheduler_tick(), which is invoked by
update_process_times(), which subsequently invokes
run_posix_cpu_timers()) So there is no special processing necessary
wrt. that.
In other contexts, we have to allot for the fact that tsk->sched_time
might be a bit out of date if we are current. And the
posix-cpu-timers.c code uses current_sched_time() to deal with that.
Unfortunately it does so in an erroneous and inconsistent manner in
one spot which is what results in the early timer firing.
In cpu_clock_sample_group_locked(), it does this:
cpu->sched = p->signal->sched_time;
/* Add in each other live thread. */
while ((t = next_thread(t)) != p) {
cpu->sched += t->sched_time;
}
if (p->tgid == current->tgid) {
/*
* We're sampling ourselves, so include the
* cycles not yet banked. We still omit
* other threads running on other CPUs,
* so the total can always be behind as
* much as max(nthreads-1,ncpus) * (NSEC_PER_SEC/HZ).
*/
cpu->sched += current_sched_time(current);
} else {
cpu->sched += p->sched_time;
}
The problem is the "p->tgid == current->tgid" test. If "p" is
not current, and the tgids are the same, we will add the process
t->sched_time twice into cpu->sched and omit "p"'s sched_time
which is very very very wrong.
posix-cpu-timers.c has a helper function, sched_ns(p) which takes care
of this, so my fix is to use that here instead of this special tgid
test.
The fact that current can be one of the sub-threads of "p" points out
that we could make things a little bit more accurate, perhaps by using
sched_ns() on every thread we process in these loops. It also points
out that we don't use the most accurate value for threads in the group
actively running other cpus (and this is mentioned in the comment).
But that is a future enhancement, and this fix here definitely makes
sense.

Now when a user-space client application attempts to connect to the server

The reply/x25_sendmsg() will fail, because the new socket created on

NFS: Send valid mode bits to the server
inode->i_mode contains a lot more than just the mode bits. Make sure that
we mask away this extra stuff in SETATTR calls to the server.

SUNRPC: get rid of cl_chatty
Clean up: Every ULP that uses the in-kernel RPC client, except the NLM
client, sets cl_chatty. There's no reason why NLM shouldn't set it, so
just get rid of cl_chatty and always be verbose.
Test-plan:
Compile with CONFIG_NFS enabled.

SUNRPC: transport switch API for setting port number
At some point, transport endpoint addresses will no longer be IPv4. To hide
the structure of the rpc_xprt's address field from ULPs and port mappers,
add an API for setting the port number during an RPC bind operation.
Test-plan:
Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked.
Probably need to rig a server where certain services aren't running, or
that returns an error for some typical operation.
