2008-02-11DM9000: Use netif_msg to enable debugging optionsBen Dooks
Use the netif_msg_*() macros to enable the debugging based on the board's msg_enable field. The output still goes via the dev_dbg() macros, so will be tagged and output as appropriate. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Remove unnecessary changelog in header commentBen Dooks
We have a perfectly good version control system, so we do not need to duplicate change comments in the header for this code. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Ensure spinlock held whilst accessing EEPROM registersBen Dooks
Ensure we hold the spinlock whilst the registers and being modified even though we hold the overall lock. This should protect against an interrupt happening whilst we are using the device. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Remove EEPROM initialisation code.Ben Dooks
Remove the old hack to program an initial EEPROM setting into the DM9000 as we now have ethtool support for reading and writing the EEPROM. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Add ethtool control of msg_enable valueBen Dooks
Allow the msg_enable value to be read and written by the ethtool interface. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Add ethtool support for reading and writing EEPROMBen Dooks
Add ethtool support to access the configuration EEPROM connected to the DM9000. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Add mutex to protect accessBen Dooks
Add a mutex to serialise access to the chip functions from entries such as the ethtool and the MII code. This should reduce the amount of time the spinlock is held to protect the address register. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Remove barely used SROM array read.Ben Dooks
The srom array in the board data is only being used in the device probe routines. The probe also only uses the first 6 bytes of an array we spend 512ms reading 128 bytes from. Change to reading the MAC area directly to the MAC address structure. As a side product, we rename the read_srom_word to dm9000_read_eeprom to bring it into line with the rest of the driver. No change is made to the delay in this function, which will be dealt with in a later patch. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Use msleep() instead of udelay()Ben Dooks
We can use sleeping functions when reading and writing the PHY registers, so let us sleep instead of busy waiting for the PHY. Note, this also fixes a bug reading the PHY where only 100uS was being used instead of 150uS Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Do not sleep with spinlock and IRQs heldBen Dooks
The phy read and write routines call udelay() with the board lock held, and with the posibility of IRQs being disabled. Since these delays can be up to 500usec, and are only required as we have to save the chip's address register. To improve the behaviour, hold the lock whilst we are writing and then restore the state before the delay and then repeat the process once the delay has happened.

2008-02-11DM9000: Remove old timer based poll routinesBen Dooks
Remove the timer based MII phy polling, as this is currently broken with the new EEPROM code that now uses mutexes to protect the phy access. This will need to be replaced in the future by some form of mutex safe mechanism for reading the MII phy status. The replacement has not been done here as changing this patch, which is early in the sequence has quite a knock-on effect. Once this series is merged, then a new presentation of an patch to poll the MII link status can be added. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Pass IRQ flags via platform resourcesBen Dooks
Use the flags in the IRQ resource to specify the type of IRQ being requested, so that systems which do not have level-based interrupts, or change the interrupt in some other way can specify this without making an #ifdef mess in the driver. This is specifically designed to undo the change in commit 4e4fc05a2b6e7bd2e0facd96e0c18dceb34d9349 which hardwires the type for everyone but blackfin to IRQT_RISING, which breaks all a number of Simtec boards which use (and setup in the bootloader) active low IRQs. Note, although there where originally objections due to the use of IORESOURCE_IRQ and IRQT_ flags not sharing the same definition, at least <include/linux/interrupt.h> notes these are the same.

2008-02-11Optimize cxgb3 xmit path (a bit)Krishna Kumar
1. Add common code for stopping queue. 2. No need to call netif_stop_queue followed by netif_wake_queue (and infact a netif_start_queue could have been used instead), instead call stop_queue if required, and remove code under USE_GTS macro. 3. There is no need to check for netif_queue_stopped, as the network core guarantees that for us (I am sure every driver could remove that check, eg e1000 - I have tested that path a few billion times with about a few hundred thousand qstops but the condition never hit even once).

2008-02-11e1000: Fix for 32 bits platforms with 64 bits resourcesBenjamin Herrenschmidt
The e1000 driver stores the content of the PCI resources into unsigned long's before ioremapping. This breaks on 32 bits platforms that support 64 bits MMIO resources such as ppc 44x. This fixes it by removing those temporary variables and passing directly the result of pci_resource_start/len to ioremap. The side effect is that I removed the assignments to the netdev fields mem_start, mem_end and base_addr, which are totally useless for PCI devices.

2008-02-11PS3: gelic: Add support for dual network interfaceMasakazu Mokuno
Add support for dual network (net_device) interface so that ethernet and wireless can own separate ethX interfaces. V2 - Fix the bug that bringing down and up the interface keeps rx disabled. - Make 'gelic_net_poll_controller()' extern , as David Woodhouse pointed out at the previous submission. - Fix weird usage of member names for the rx descriptor chain V1 - Export functions which are convenient for both interfaces - Move irq allocation/release code to driver probe/remove handlers because interfaces share interrupts. - Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb() as the interfaces share the hardware rx queue. - Add gelic_port struct in order to abstract dual interface handling - Change handlers for hardware queues so that they can handle dual {source,destination} interfaces. - Use new NAPI functions This is a prerequisite for the new PS3 wireless support.

Code cleanup: - Use appropriate prefixes for names instead of fixed 'gelic_net' so that objects of the functions, variables and constants can be estimated. - Remove definitions for IPSec offload to the gelic hardware. This functionality is never supported on PS3. - Group constants with enum. - Use bitwise constants for interrupt status, instead of bit numbers to eliminate shift operations. - Style fixes.

2008-02-11ide-disk: fix flush requests (take 2)Bartlomiej Zolnierkiewicz
commit 813a0eb233ee67d7166241a8b389b6a76f2247f9 Author: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Date: Fri Jan 25 22:17:10 2008 +0100 ide: switch idedisk_prepare_flush() to use REQ_TYPE_ATA_TASKFILE requests ... broke flush requests. Allocating IDE command structure on the stack for flush requests is not a very brilliant idea: - idedisk_prepare_flush() only prepares the request and it doesn't wait for it to be completed - there are can be multiple flush requests queued in the queue Fix the problem (per hints from James Bottomley) by: - dynamically allocating ide_task_t instance using kmalloc(..., GFP_ATOMIC) - adding new taskfile flag (IDE_TFLAG_DYN) - calling kfree() in ide_end_drive_command() if IDE_TFLAG_DYN is set (while at it rename 'args' to 'task' and fix whitespace damage) [ This will be fixed properly before 2.6.25 but this bug is rather critical and the proper solution requires some more work + testing. ] Thanks to Sebastian Siewior and Christoph Hellwig for reporting the problem and testing patches (extra thanks to Sebastian for bisecting it to the guilty commmit).

2008-02-11ide: another possible ide panic fix for blk-end-requestKiyoshi Ueda
I have reviewed all blk-end-request patches again to confirm whether there are any similar problems with the last week's ide-cd panic: http://lkml.org/lkml/2008/1/29/140 And I found a possible similar bug in ide-io change: ide_end_drive_cmd() could be called for blk_pc_request() which could have bios. To complete such requests correctly, we need to pass the actual size of the request. Otherwise, __blk_end_request() returns 1 because the request still has bios, and the system will BUG() unnecessarily. The following patch fixes the bug and should be applied on top of Linus' git.
