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:

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:

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:

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:

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 authored
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. Signed-off-by:

Ben Dooks authored
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 authored
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 4e4fc05a 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.

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).

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. Signed-off-by:

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.

Mark the members of the structure for DMA descriptors with proper endian annotations and use the appropriate accessor macros. As the gelic driver works only on PS3, all these macros will be expanded to null. Signed-off-by:

We want to allow different implementations of pci_raw_ops for standard and extended config space on x86. Rather than clutter generic code with knowledge of this, we make pci_raw_ops private to x86 and use it to implement the new raw interface -- raw_pci_read() and raw_pci_write(). Signed-off-by:

Thanks to Loic Prylli <loic@myri.com>, who originally proposed this idea. Always using legacy configuration mechanism for the legacy config space and extended mechanism (mmconf) for the extended config space is a simple and very logical approach. It's supposed to resolve all known mmconf problems. It still allows per-device quirks (tweaking dev->cfg_size). It also allows to get rid of mmconf fallback code. Signed-off-by:

Commit 8811930d ("splice: missing user pointer access verification") added the proper access_ok() calls to copy_from_user_mmap_sem() which ensures we can copy the struct iovecs from userspace to the kernel. But we also must check whether we can access the actual memory region pointed to by the struct iovec to fix the access checks properly. Signed-off-by:

hrtimer_nanosleep_restart() clears/restores restart_block->fn. This is pointless and complicates its usage. Note that if sys_restart_syscall() doesn't actually happen, we have a bogus "pending" restart->fn anyway, this is harmless. Signed-off-by:

Spotted by Pavel Emelyanov and Alexey Dobriyan. compat_sys_nanosleep() implicitly uses hrtimer_nanosleep_restart(), this can't work. Make a suitable compat_nanosleep_restart() helper. Introduced by commit c70878b4 hrtimer: hook compat_sys_nanosleep up to high res timer code Also, set ->addr_limit = KERNEL_DS before doing hrtimer_nanosleep(), this func was changed by the previous patch and now takes the "__user *" parameter. Thanks to Ingo Molnar for fixing the bug in this patch. Signed-off-by:

Spotted by Pavel Emelyanov and Alexey Dobriyan. hrtimer_nanosleep() sets restart_block->arg1 = rmtp, but this rmtp points to the local variable which lives in the caller's stack frame. This means that if sys_restart_syscall() actually happens and it is interrupted as well, we don't update the user-space variable, but write into the already dead stack frame. Introduced by commit 04c22714 hrtimer: Rework hrtimer_nanosleep to make sys_compat_nanosleep easier Change the callers to pass "__user *rmtp" to hrtimer_nanosleep(), and change hrtimer_nanosleep() to use copy_to_user() to actually update *rmtp. Small problem remains. man 2 nanosleep states that *rtmp should be written if nanosleep() was interrupted (it says nothing whether it is OK to update *rmtp if nanosleep returns 0), but (with or without this patch) we can dirty *rem even if nanosleep() returns 0. NOTE: this patch doesn't change compat_sys_nanosleep(), because it has other bugs. Fixed by the next patch. Signed-off-by:
