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.

- 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.
Thanks to Will Schmidt who tracked this down.

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.

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.
The patch below makes the nescesarry 1 char change :)
