[ARCNET]: Use menuconfig objects.

2007-05-24T23:36:51+00:00

Use menuconfigs instead of menus, so the whole menu can be disabled at once instead of going through all options. Signed-off-by: Jan Engelhardt Signed-off-by: Andrew Morton Signed-off-by: David S. Miller

[SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}

2007-04-26T05:28:23+00:00

To clearly state the intent of copying from linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo

[SK_BUFF]: unions of just one member don't get anything done, kill them

2007-04-26T05:26:20+00:00

Renaming skb->h to skb->transport_header, skb->nh to skb->network_header and skb->mac to skb->mac_header, to match the names of the associated helpers (skb[_[re]set]_{transport,network,mac}_header). Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[SK_BUFF]: Introduce skb_mac_header()

2007-04-26T05:24:41+00:00

For the places where we need a pointer to the mac header, it is still legal to touch skb->mac.raw directly if just adding to, subtracting from or setting it to another layer header. This one also converts some more cases to skb_reset_mac_header() that my regex missed as it had no spaces before nor after '=', ugh. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[SK_BUFF]: Introduce skb_reset_mac_header(skb)

2007-04-26T05:24:32+00:00

For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

bugfixes and new hardware support for arcnet driver

2007-02-17T20:30:48+00:00

The modifications and bug fixes noted below were done by Realtime Control Works and Contemporary Control Systems, Inc, Jan 2005. They were incorporated into the 2.6 kernel by Jeff Morrow of Sierra Analytics, Feb 2007. The changes have been tested on a Contemporary Controls PCI20U-4000. Summary of changes: Arc-rawmode.c: rx(): - Fixed error in received packet lengths; 256 byte packets were being received as 257 bytes packets. prepare_tx(): - Fixed error in transmit length calcs; 257 byte packets were being transmitted as 260 byte packets. com20020.c: com20020_check(): - We now load the SETUP2 register if the 'clockm' parameter is non-zero, instead of checking for ARC_CAN_10MBIT. The user is now responsible for whether or not SETUP2 is loaded. If the clock multiplier is non-zero, this means that the user wants a baud rate greater than 2.5Mbps. This is not possible unless the SETUP2 register is present (COM20020D, or COM20022). So, we're relying on the user to be smart about what kind of chip he's dealing with... com20020-pci.c - Added several entries to com20020pci_id_table[]. Signed-off-by: Jeff Morrow Cc: "David S.

[PATCH] com20020 build fix

2006-11-10T16:08:53+00:00

com20020.c needs to export functions if either of the ISA or PCI modules are built as loadable modules. Or they could always be exported.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers

2006-10-05T14:10:12+00:00

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. Signed-Off-By: David Howells (cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)
