Gcc might re-order MMIO accessors vs. surrounding consistent memory accesses, which is a "bad thing", and could break drivers. This fixes it by adding a "memory" clobber to the MMIO accessors, which should prevent gcc from doing that reordering.

The following commit (4c9bf4e7): libata: replace tf_read with qc_fill_rtf for non-SFF drivers Broke the sata_fsl.c driver in 2.6.26-rc. I know the following patch fixes the issue, it clearly also adds port multipler support. The current 2.6.26-rc driver is broken. On boot with debug enabled we get something like (w/o this patch): spurious interrupt!!, CC = 0x1 interrupt status 0x1 xx_scr_read, reg_in = 1 spurious interrupt!!, CC = 0x1 interrupt status 0x1 xx_scr_read, reg_in = 1 spurious interrupt!!, CC = 0x1 interrupt status 0x1 xx_scr_read, reg_in = 1 .. continues for ever. This change fixes this as a side effect of adding port multiplier support. Signed-off-by: Ashish Kalra <ashish.kalra@freescale.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

ICH8M on macbooks are peculiar in that some of them lock up when the second port is enabled, some return bogus values on SIDPR access while yet others hang on SIDPR access. Also, the ich8m_apple_sata entry was wrongly added below generic ich8m entry making it virtually useless. This patch works around macbook ich8m problems by * moving ich8m_apple_sata entry above generic ich8m entry * dropping PIIX_FLAG_SIDPR from ich8m_apple_sata * adding subsystem 106b:00a1 as ich8m_apple_sata Reported and tested by MATSUBAYASHI.

The 5182 System-On-Chip (SOC) variant wants certain lower bits to be cleared on any write to the PHY_MODE3 register. If/when support is added for other SOC variants, we'll need some way to uniquely identify the 5182, and not perform this workaround for the others. But for now, it is the only SOC variant we support here. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Convert the System-on-Chip flag from a host flag to an hpriv flag, for better consistency with other chip-rev flags, and for easier use in errata fixes etc. Also change the related "HAS_PCI()" into "!IS_SOC()" for better consistency of naming/use (everything else SOC-related already uses "SOC").

The SW_RADIO code for EV_SW events has a name that is not descriptive enough of its intended function, and could induce someone to think KEY_RADIO is its EV_KEY counterpart, which is false. Rename it to SW_RFKILL_ALL, and document what this event is for. Keep the old name around, to avoid userspace ABI breaks. The SW_RFKILL_ALL event is meant to be used by rfkill master switches. It is not bound to a particular radio switch type, and usually applies to all types. It is semantically tied to master rfkill switches that enable or disable every radio in a system.

llc_sap_rcv was being preceded by skb_set_owner_r, then calling llc_state_process that calls sock_queue_rcv_skb, that in turn calls skb_set_owner_r again making the space allowed to be used by the socket to be leaked, making the socket to get stuck. Fix it by setting skb->sk at llc_sap_rcv and leave the accounting to be done only at sock_queue_rcv_skb.

The driver incorrectly assumed that putchar will only be called from schedulable process context and therefore blocked and waited if no free output buffers where available. Since putchar may also be called from BH context this may lead to deadlocks. To fix this just return the number of characters accepted and let the upper layer handle the rest. The console write function will busy wait (sclp_sync_wait) until a buffer is available again.

This fixes the last remaining section mismatch warnings in s390 architecture code. It reveals also a real bug introduced by... me with git commit 2069e978 ("[S390] sparsemem vmemmap: initialize memmap.") Calling the generic vmemmap_alloc_block() function to get initialized memory is a nice idea, however that function is __meminit annotated and therefore the function might be gone if we try to call it later. This can happen if a DCSS segment gets added. So basically revert the patch and clear the memmap explicitly to fix the original bug.

Due to incorrect function call sequence it can happen that a tape block request is finished before the request is taken from the block request queue. The following sequence leads to that condition: * tapeblock_start_request() -> start CCW program * Request finishes -> IO interrupt * tapeblock_end_request() * end_that_request_last() If blkdev_dequeue_request() has not been called before end_that_request_last(), a kernel bug is triggered in end_that_request_last() because the request is still queued. To solve that problem blkdev_dequeue_request() has to be called before starting the CCW program.
