2005-06-25Merge Christoph's freeze cleanup patchLinus Torvalds
2005-06-25[PATCH] Cleanup patch for process freezingChristoph Lameter
1. Establish a simple API for process freezing defined in linux/include/sched.h: frozen(process) Check for frozen process freezing(process) Check if a process is being frozen freeze(process) Tell a process to freeze (go to refrigerator) thaw_process(process) Restart process frozen_process(process) Process is frozen now 2. Remove all references to PF_FREEZE and PF_FROZEN from all kernel sources except sched.h 3. Fix numerous locations where try_to_freeze is manually done by a driver 4. Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE. This is not clean in an SMP environment. freeze(process) is therefore not SMP safe! Signed-off-by: Christoph Lameter <christoph@lameter.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-24[TG3]: Refinements to new locking strategy.Michael Chan
1. Move tp->irq_sync = 0 to before the interrupt mailbox IO in tg3_enable_ints() so that the interrupt handler will always see irq_sync == 0 when interrupts are enabled. 2. Remove the tg3_enable_ints() call in tg3_reset_hw(). Interrupts are always enabled explicitly or through tg3_netif_start(). This is to prevent interrupts being enabled while poll is disabled. 3. Update trans_start with jiffies in tg3_netif_stop() to prevent false NETDEV WATCHDOG. 4. Pass in the proper irq_sync parameter to tg3_full_lock() depending on netif_running() in some of the ethtool set calls. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2005-06-24[TG3]: Eliminate all hw IRQ handler spinlocks.David S. Miller
Move all driver spinlocks to be taken at sw IRQ context only. This fixes the skb_copy() we were doing with hw IRQs disabled (which is illegal and triggers a BUG() with HIGHMEM enabled). It also simplifies the locking all over the driver tremendously. We accomplish this feat by creating a special sequence to synchronize with the hw IRQ handler using a binary state and synchronize_irq(). This idea is from Herbert Xu. Thanks to Michael Chan for helping to track down all of the race conditions in initial versions of this code. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-06-24[TG3]: Fix missing memory barriers and SD_STATUS_UPDATED bit clearing.David S. Miller
There must be a rmb() between reading the status block tag and calling tg3_has_work(). This was missing in tg3_mis() and tg3_interrupt_tagged(). tg3_poll() got it right. Also, SD_STATUS_UPDATED must be cleared in the status block right before we call tg3_has_work(). Only tg3_poll() got this wrong. Based upon patches and commentary from Grant Grundler and Michael Chan. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-06-23[SLIP]: Simplify sl_free_bufs()Jesper Juhl
We can avoid assignments to the local variable 'tmp' and actually get rid of tmp alltogether in sl_free_bufs(). This patch does that. This is safe since both kfree() and slhc_free() handles NULL pointers gracefully. Signed-off-by: Jesper Juhl <juhl-lkml@dif.dk> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-06-09[PATCH] iseries_veth: Supress spurious WARN_ON() at module unloadMichael Ellerman
My patch from a few weeks back (now in mainline), called "Cleanup skbs to prevent unregister_netdevice() hanging", can cause our TX timeout code to fire on machines with lots of VLANs (because it takes > 2 seconds between when we stop the queues and when we're finished stopping the connections). When that happens the TX timeout code freaks out and does a WARN_ON() because as far as it's concerned there shouldn't be a TX timeout happening, which is fair enough. I have a "proper" fix for this, which is to a) do refcounting on connections and b) implement a proper ack timer so we don't keep unacked skbs lying around for ever. But for 2.6.12 I propose just supressing the WARN_ON(). Users will still see the "NETDEV WATCHDOG" warning, but that's not nearly as bad as a WARN_ON() which users interpret as an Oops.

2005-06-06[TG3] Fix link failure in 5701Michael Chan
On some 5701 devices with older bootcode, the LED configuration bits in SRAM may be invalid with value zero. The fix is to check for invalid bits (0) and default to PHY 1 mode. Incorrect LED mode will lead to error in programming the PHY. Thanks to Grant Grundler for debugging the problem. >From Grant: | In May, 2004, tg3 v3.4 changed how MAC_LED_CTRL (0x40c) was getting | programmed and how to determine what to program into LED_CTRL. The new | code trusted NIC_SRAM_DATA_CFG (0x00000b58) to indicate what to write | to LED_CTRL and MII EXT_CTRL registers. On "IOX Core Lan", SRAM was | saying MODE_MAC (0x0) and that doesn't work.

2005-05-29[TG3]: Fix bug in tg3_load_firmware_cpuMichael Chan
Add tg3_nvram_lock() and tg3_nvram_unlock() calls around tg3_halt_cpu(). It is possible that the bootcode may be loading code from nvram during this call and stopping the cpu without getting the lock may cause uncompleted nvram data to be left in the nvram data register.
