2007-06-03network drivers: eliminate unneeded kill_vid codeStephen Hemminger
Many drivers had code that did kill_vid, but they weren't doing vlan filtering. With new API the stub is unneeded unless device sets NETIF_F_HW_VLAN_FILTER. Bad habit: I couldn't resist fixing a couple of nearby style things in acenic, and forcedeth.

2007-03-02[VLAN]: Avoid a 4-order allocation.Dan Aloni
This patch splits the vlan_group struct into a multi-allocated struct. On x86_64, the size of the original struct is a little more than 32KB, causing a 4-order allocation, which is prune to problems caused by buddy-system external fragmentation conditions. I couldn't just use vmalloc() because vfree() cannot be called in the softirq context of the RCU callback.

2007-02-27chelsio: Fix non-NAPI compileRoland Dreier
Chelsio without NAPI enabled has been broken (won't compile) since 3de00b89 ("chelsio: NAPI speed improvement"): drivers/net/chelsio/sge.c: In function `t1_interrupt`: drivers/net/chelsio/sge.c:1716: error: `Q` undeclared (first use in this function) The change below seems to add back in the declaration and initialization of `Q` that was removed by mistake, and at least makes the driver compile for me, although I have no hardware and hence no way to test whether this actually works.

Let's try to avoid some code duplication. - cxgb2 The data are contiguous. Use plain memcpy. - ixf1010/pm3393/vsc7326 The cast of &mac->stats to (u64 *) is not wonderful but it is not clear if it is worth to add an ad-hoc union under the struct cmac_statistics. vsc7326_reg.h suggests that more statistics could be available.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
