rtc: ignore msb when reading back mday from alarm
I have a system here that actively relies upon RTC wake alarms, and it
has been failing (again) for a few days when attempting to use the
/sys/class/rtc/rtc?/wakealarm interface.
The old (fixed by Linus) /proc/ interface still works, but I'd like to
get it using the new one.
This patch fixes rtc-cmos to ignore the two upper bits when reading the
BCD mday (day of month) register from CMOS. Some systems (eg. mine)
seem to have the top bit set to "1" for some reason.
The older /proc/ interface ignores the upper bits, and so we should too.

libata: increase 128 KB / cmd limit for ATAPI tape drives
Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are
limited in the amount of data that they can transfer by the max_sectors
value. The max_sectors value is currently calculated according to the
command set for disk drives, which doesn't apply to tape drives. The
default max_sectors value of 256 limits ATAPI tape drive commands to
128 KB. This patch against 2.6.24-rc1 increases the max_sectors value
for tape drives to 65535, which permits tape drive commands to transfer
just under 32 MB.
Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V
SATA tape drive.
Note that some of the chipset drivers also set their own max_sectors
value, which may override the value set in libata-core. I don't have
any of these chipsets to test, so I didn't go messing with them. Also,
ATAPI devices other than tape drives may benefit from similar changes,
but I have only tape drives and disk drives to test.

Fix myri10ge NAPI oops & warnings
When testing the myri10ge driver with 2.6.24-rc1, I found
that the machine crashed under heavy load:
Unable to handle kernel paging request at
0000000000100108 RIP:
[<
ffffffff803cc8dd>] net_rx_action+0x11b/0x184
The address corresponds to the list_move_tail() in
netif_rx_complete():
if (unlikely(work == weight))
list_move_tail(&n->poll_list, list);
Eventually, I traced the crashes to calling netif_rx_complete() with
work_done == budget. From looking at other drivers, it appears that
one should only call netif_rx_complete() when work_done < budget.
To fix it, I changed the test in myri10ge_poll() so that it refers
to to work_done rather than looking at the rx ring status. If
work_done is < budget, then that implies we have no more packets to
process. Any races will be resolved by the NIC when the write to
irq_claim is made.
In myri10ge_clean_rx_done(), if we ever exceeded our budget, it would
report a work_done one larger than was acutally done. This is because
the increment was done in the conditional, so work_done would be
incremented regardless of whether or not the test passed or failed.
This would lead to the WARN_ON_ONCE(work > weight); warning in
net_rx_action triggering. I've moved the increment of work_done
inside the loop. Note that this would only be a problem when we had
exceeded our budget.
