A change I made for 2.6.17 and another for 2.6.18 do not work on older
pcnet32 chips which I do not have access to.  If the chip is a 79C970 or
79C965, do not try and suspend or check the link status.
I have tested with a 79C970A, 79C971, 79C972, 79C973, 79C975, 79C976,
and 79C978.

cb958186ed [PATCH] Signedness issue in drivers/net/3c515.c
while playing with gcc 4.1 -Wextra warnings, I came across this one:

drivers/net/3c515.c:1027: warning: comparison of unsigned expression >= 0 is always true

Since i is unsigned the >= 0 check in the for loop is always true,
so we might spin there forever unless the if condition triggers.
Since i is only used in this loop, this patch changes it to
an integer.

c9169f8747 [POWERPC] hugepage BUG fix
On Tue, 2006-08-15 at 08:22 -0700, Dave Hansen wrote:
> kernel BUG in cache_free_debugcheck at mm/slab.c:2748!

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.

0f4184f73d [SERIAL] sunsab: Fix E250 console with RSC.
This fixes yet another sunsab problem, when console is set to anything
but the first port. The console framework calls sunsab_console_setup
for each port, and we end up setting up a console on a not yet
discovered port, which leads to an Oops. Instead, defer console setup
until the requested port is properly initialized. Tested on an E250
through an RSC console.

87589f08be [POWERPC] Correct masks used in emulating some instructions
When we get an illegal instruction exception, we check to see whether
the instruction is one that we emulate for the user program.  Some of
the masks we use in checking whether the offending instruction is one
we care about didn't have the top bit set, which is the MSB of the
major opcode.  Thus some undefined opcodes could get emulated as other
(defined but unimplemented) instructions.  This corrects the masks.

5db9fa9593 [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.

Move out PCS handling from piix_sata_prereset() into
piix_sata_present_mask() and use it from newly implemented
piix_sata_softreset().  Class codes for devices which are indicated to
be absent by PCS are cleared to ATA_DEV_NONE.  This fixes ghost device
problem reported on ICH6 and 7.

This patch moves PCS handling from prereset to softreset, which makes
two behavior changes.

* perform softreset even when PCS indicates no device
* PCS handling is repeated before retrying softresets due to reset
  failures.

Both behavior changes are intended and more consistent with how other
drivers behave.
