* [PATCH] Set the vga cursor even when hiddenSamuel Thibault2005-11-05
| | | | | | | | | | | | | | | | | Some visually impaired people use hardware devices which directly read the vga screen. When newt for instance asks to hide the cursor for better visual aspect, the kernel puts the vga cursor out of the screen, so that the cursor position can't be read by the hardware device. This is a great loss for such people. Here is a patch which uses the same technique as CUR_NONE for hiding the cursor while still moving it. Mario, you should apply it to the speakup kernel for access floppies asap. I'll submit a 2.4 patch too. Signed-off-by: samuel.thibault@ens-lyon.org Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [PATCH] phy address mask support for generic phy layerMatt Porter2005-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a phy_mask field to struct mii_bus and uses it. This field indicates each phy address to be ignored when probing the mdio bus. This support is needed for the fs_enet and ibm_emac drivers to be converted to the generic phy layer among other drivers. Many systems lock up on probing certain phy addresses or probing doesn't return 0xffff when nothing is found at the address. A new driver I'm working on also makes use of this mask.

| * [PATCH] pcnet32: Prevent hang with 79c976Don Fry2005-11-05
| | | | | | | | | | | | | | | | | | | | | | | | Some boards using the 79c976 pcnet32 chip will hang the system if the ethtool --register-dump is performed with the device operational. The request to read bcr30 is retried by the PCI device infinitely without returning data, hanging the system. Tested ia32 and ppc64.

| | | | | | | | | | | | | | | | | | | | | | This patch is a better fix for Allied Telesyn 2700/2701 FX boards than the change made in early January this year. It allows the user to select the speed/duplex via module_param, but if no selection is made, forces the speed to 100 FD. It fixes both Bugzilla bugs 2669 and 4551.

When changing ring size via ethtool, it also releases the lock before returning on error. Added comment that the caller of pcnet32_alloc_ring must call pcnet32_free_ring on error, to avoid leak.

| * [PATCH] S2io: Multi buffer mode supportAnanda Raju2005-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, This patch provides dynamic two buffer-mode and 3 buffer-mode options. Previously 2 buffer-mode was compilation option. Now with this patch applied one can load driver in 2 buffer-mode with module-load parameter ie. #insmod s2io.ko rx_ring_mode=2 This patch also provides 3 buffer-mode which provides header separation functionality. In 3 buffer-mode skb->data will have L2/L3/L4 headers and "skb_shinfo(skb)->frag_list->data" will have have L4 payload. one can load driver in 3 buffer-mode with same above module-load parameter ie. #insmod s2io.ko rx_ring_mode=3 Please review the patch.

The patch also makes the scsi_disk keep a reference to the underlying scsi_device, and it erases the scsi_device's pointer to the scsi_disk when the scsi_device is removed (since the pointer should no longer be used).

The flush cache allows any pending "lazy writes" that the adapter is processing to complete ( a "must have" for a RAID adapter ) and the reset puts the adapter back into a known, good state.

When we perform the reset, we wanted to tear down the internal data structures and rebuild them. Unfortunately, when it came to the rport structure, things were odd. If we deleted them, the scsi targets and sdevs would be torn down. Not a good thing for a temporary reset. We could block the rports, but we either maintain the internal structures to keep the rport reference (perhaps even replicating what's in the transport), or we have to fatten the fc transport with new search routines to find the rport (and deal with a case of a dangling rport that the driver forgets). It dawned on me that we had actually reached this state incorrectly. When the fc transport first started, we did the block/unblock first, then added the rport interface. The purpose of block/unblock is to hide the temporary disappearance of the rport (e.g. being deleted, then readded). Why are we making the driver do the block/unblock ? We should be making the transport have only an rport add/delete, and the let the transport handle the block/unblock. So... This patch removes the existing fc_remote_port_block/unblock functions. It moves the block/unblock functionality into the fc_remote_port_add/delete functions. Updates for the lpfc driver are included. Qlogic driver updates are also enclosed, thanks to the contributions of Andrew Vasquez. [Note: the qla2xxx changes are relative to the scsi-misc-2.6 tree as of this morning - which does not include the recent patches sent by Andrew]. The zfcp driver does not use the block/unblock functions. One last comment: The resulting behavior feels very clean. The LLDD is concerned only with add/delete, which corresponds to the physical disappearance. However, the fact that the scsi target and sdevs are not immediately torn down after the LLDD calls delete causes an interesting scenario... the midlayer can call the xxx_slave_alloc and xxx_queuecommand functions with a sdev that is at the location the rport used to be. The driver must validate the device exists when it first enters these functions. In thinking about it, this has always been the case for the LLDD and these routines. The existing drivers already check for existence. However, this highlights that simple validation via data structure dereferencing needs to be watched. To deal with this, a new transport function, fc_remote_port_chkready() was created that LLDDs should call when they first enter these two routines. It validates the rport state, and returns a scsi result which could be returned. In addition to solving the above, it also creates consistent behavior from the LLDD's when the block and deletes are occuring.
