ip_summed changes last summer had missed that one. As the result, we have ip_summed interpreted as CHECKSUM_PARTIAL now. IOW, ->csum is interpreted as offset of checksum in the packet. net/core/* will both read and modify the value as that offset, with obvious reasons. At the very least it's a remote memory corruptor.

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.

This patch makes tms380tr use the new DMA API. Now that on Alpha, this API also supports bus master DMA for ISA (platform) devices, i changed the driver to use this new API. This also works around a bug in the firmware loader: The example provided in Documentation/firmware_class no longer works, as the firmware loader now calls get_kobj_path_length() and the kernel promptly oopses, as the home-grown device doesn't have a parent. Of course, this doesn't happen with a "real" device which has its bus (or pseudo bus in the case of platform) as parent. Converted tms380tr to use new DMA API: - proteon.c, skisa.c: use platform pseudo bus to create a struct device - Space.c: delete init hooks - abyss.c, tmspci.c: pass struct device to tms380tr.c - tms380tr.c, tms380tr.h: new DMA API, use real device fo firmware loader Signed-off-by: NJochen Friedrich <jochen@scram.de> Cc: Jeff Garzik <jgarzik@pobox.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NJeff Garzik <jgarzik@pobox.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
