Alright, this one is only triggered when slab debugging is enabled.  The
slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary.  The free
path makes use of this assumption and uses the lowest nibble to pass around
an index into an array of kmem_cache pointers.  With slab debugging turned
on, the slab is still aligned, but the "working" object pointer is not.
This would break the assumption above that a full nibble is available for
the PGF_CACHENUM_MASK.

The following patch reduces PGF_CACHENUM_MASK to cover only the two least
significant bits, which is enough to cover the current number of 4 pgtable
cache types.  Then use this constant to mask out the appropriate part of
the huge pte pointer.

[POWERPC] Fix gettimeofday inaccuracies

There are two problems in the powerpc gettimeofday code which can
cause incorrect results to be returned.

The first is that there is a race between do_gettimeofday and the
timer interrupt:

1. do_gettimeofday does get_tb()

2. decrementer exception on boot cpu which runs timer_recalc_offset,
   which also samples the timebase and updates the do_gtod structure
   with a greater timebase value.

3. do_gettimeofday calls __do_gettimeofday, which leads to the
   negative result from tb_val - temp_varp->tb_orig_stamp.

The second is caused by taking the boot cpu offline, which can cause
the value of tb_last_jiffy to be increased past the currently
available timebase, causing the same underflow as above.

[BNX2]: Fix tx race condition.

Fix a subtle race condition between bnx2_start_xmit() and bnx2_tx_int()
similar to the one in tg3 discovered by Herbert Xu:

CPU0 CPU1
bnx2_start_xmit()
if (tx_ring_full) {
tx_lock
bnx2_tx()
if (!netif_queue_stopped)
netif_stop_queue()
if (!tx_ring_full)
update_tx_ring
netif_wake_queue()
tx_unlock
}

Even though tx_ring is updated before the if statement in bnx2_tx_int() in
program order, it can be re-ordered by the CPU as shown above.  This
scenario can cause the tx queue to be stopped forever if bnx2_tx_int() has
just freed up the entire tx_ring.  The possibility of this happening
should be very rare though.

The following changes are made, very much identical to the tg3 fix:

1. Add memory barrier to fix the above race condition.

2. Eliminate the private tx_lock altogether and rely solely on
netif_tx_lock.  This eliminates one spinlock in bnx2_start_xmit()
when the ring is full.

3. Because of 2, use netif_tx_lock in bnx2_tx_int() before calling
netif_wake_queue().

4. Add memory barrier to bnx2_tx_avail().

5. Add bp->tx_wake_thresh which is set to half the tx ring size.

6. Check for the full wake queue condition before getting
netif_tx_lock in tg3_tx().  This reduces the number of unnecessary
spinlocks when the tx ring is full in a steady-state condition.

[POWERPC] kprobes: Fix possible system crash during out-of-line single-stepping

- On archs that have no-exec support, we vmalloc() a executable scratch
area of PAGE_SIZE and divide it up into an array of slots of maximum
instruction size for that arch
- On a kprobe registration, the original instruction is copied to the
first available free slot, so if multiple kprobes are registered, chances
are, they get contiguous slots
- On POWER4, due to not having coherent icaches, we could hit a situation
where a probe that is registered on one processor, is hit immediately on
another. This second processor could have fetched the stream of text from
the out-of-line single-stepping area *before* the probe registration
completed, possibly due to an earlier (and a different) kprobe hit and
hence would see stale data at the slot.

Executing such an arbitrary instruction lead to a problem as reported
in LTC bugzilla 23555.

The correct solution is to call flush_icache_range() as soon as the
instruction is copied for out-of-line single-stepping, so the correct
instruction is seen on all processors.

[POWERPC] Make secondary CPUs call into kdump on reset exception

In the case of a system hang, the user will invoke soft-reset to
initiate the kdump boot.  If xmon is enabled, the CPU(s) enter into the
xmon debugger.   Unfortunately, the secondary CPU(s) will return to the
hung state when they exit from the debugger (returned from die() ->
system_reset_exception()).  This causes a problem in kdump since the
hung CPU(s) will not respond to the IPI sent from kdump.  This patch
fixes the issue by calling crash_kexec_secondary() directly from
system_reset_exception() without returning to the previous state.  These
secondary CPUs wait 5ms until the kdump boot is started by the primary
CPU.   In the case we exited from the debugger to "recover" (command 'x'
in xmon) the primary and the secondary CPUs will all return from die()
-> system_reset_exception() ->crash_kexec_secondary() wait 5ms, then
return to the previous state.  A kdump boot is not started in this case.

Hans de Goede [Tue, 15 Aug 2006 10:09:27 +0000 (12:09 +0200)]
[PATCH] PATCH: 1 line 2.6.18 bugfix: modpost-64bit-fix.patch

There is a small but annoying bug in scripts/mod/file2alias.c which causes
it to generate invalid aliases for input devices on 64 bit archs. This causes
joydev.ko to not be automaticly loaded when inserting a joystick, resulting in
a non working joystick (for the average user).

In scripts/mod/file2alias.c is the following code for generating the input
aliases:
static void do_input(char *alias,
                     kernel_ulong_t *arr, unsigned int min, unsigned int max)
{
        unsigned int i;

        for (i = min; i < max; i++)
                if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG)))
                        sprintf(alias + strlen(alias), "%X,*", i);
}

On 32 bits systems, this correctly generates "0,*" for the first alias, "8,*"
for the second etc.

However on 64 bits it generates: "0,*20,*" resp "8,*28,*" Notice how it adds 20
+ first entry (hex) ! to the list of hex codes, which is 32 more then the first
entry, thus is because the bit test above wraps at 32 bits instead of 64.

scripts/mod/file2alias.c, line 379 reads:
                if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG)))
That should be:
                if (arr[i / BITS_PER_LONG] & (1L << (i%BITS_PER_LONG)))

Notice the added 'L' after the 1, otherwise that is an 32 bit int instead of a
64 bit long, and when that int gets shifted >= 32 times, appearantly the number
by which to shift is wrapped at 5 bits ( % 32) causing it to test a bit 32 bits
too low.
