Oh, and for non-x86 platforms with interesting pci mapping, this tweak to one new routine would be important in a particular error path I've yet to see ... :)

It fixes problems with interrupt transfers, which I think that nobody else has run into (or I'd surely have heard of it :). Looks like not many folk are using USB 2.0 hubs yet. - wasn't checking enough of the periodic schedule to detect bandwidth overcommit (would BUG out) - frames to uframes is rightshift 3, not 8 :) - properly cleans up (no oops!) after certain rare errors in the interrupt submit path (just my luck to hit one) - use that cleanup to bypass some old implementation shortcuts in the control and bulk submit paths - there are also some other minor updates/cleanups

general cleanups: - removed commented out function prototypes - removed duplicate function prototypes - removed unneeded #include - added named initializers - merged lots of the individual device structures into general 1, 2, and 4 port structures.

Summary of changes: - Remove palette conversion and related code - Full OV518 support (except for color), initial OV518+ support - Improved OV6620 quality (Credit: Alexandre F.) - ov51x_init_isoc() should exit if usb_submit_urb() fails - ISO completion handler should only issue warning if bad data is received - Added "mirror" module parameter; reverses image horizontally - Changed USB control transaction fields to match Windows driver - New decompression module locking (decomp_ops->owner), per Greg's advice - EXPORT_SYMBOL_NOVERS => EXPORT_SYMBOL - New devices: Lifeview USB Live TV PAL/SECAM and PAL D/K+B/G - Disabled buf_timeout feature. It was calling vfree() in interrupt context, which is illegal. Memory is deallocated immediately on close(). - Most sensors thought to be OV7620AE were actually OV76BE. Changed code to reflect this, and emit a warning if an OV7620AE is encountered. - Miscellaneous cleanups and bug fixes

This patch brings 2.5.8 in sync with the x86-64 2.4 development tree again (excluding device drivers) It has lots of bug fixes and enhancements. It only touches architecture specific files. - Sync with 2.5.8 - SMP/APIC supported now. - Module loading works now. - Time keeping bugs fixed. - entry.S streamlined and some bugs fixed. - modify_ldt works now - mostly rewritten FPU support (including FXRSTOR for initial FPU initialization based on the initial state) - 32bit emulation enhanced and bugs fixed. - rewrote mm initialization and lots of cleanups in the page table handling __PAGE_OFFSET is now moved to 0x10000000000 and some vmalloc/ioremap problems have been fixed. They have an own PML4 slot now. - WCHAN reporting support for RIP (but not RSP) - Lots of various other bug fixes and cleanups. Currently broken: - ACPI - MTRR It needs some other bugfixes outside architecture specific code. I sent them all in separate mail.

When vt_init happens to run before the keyboard is initialized (the order is random because they're both different initcalls) then set_leds raises an not yet enabled tasklet. This causes an endless loop on the first schedule() call because the tasklet handling cannot handle raised but disabled tasklets. This patch just does not do set_leds in virtual terminal initialization to avoid that. It is done later anyways.

Minor patch for the x86-64 32bit emulation. Originally proposed by hpa and it makes autofs 32bit/64bit clean for x86-64

Initialize the saved FPU/XMM state in the task struct and fall through to restore_fpu() to make sure that all state is fully initialized. This means that old SSE/SSE2 information cannot ever leak into newly created processes.

- (tcq, general) Remove the 'attempt to keep queue full option'. It worked on some IBM models, but failed miserably on others. Also removes some uglies in ide_queue_commands() - (tcq0 Change default depth back to 32. - (general) Add isr for no-dataphase taskfile, like task_no_data_intr but doesn't complain about failure. This is handy for commands what we _know_ will fail, such as WIN_NOP. - (general) ide_cmd_type_parser() must set a handler to WIN_NOP... Otherwise we will just hang the ide system issuing a nop. - (general) HWGROUP(drive)->rq->special -> IDE_CUR_AR(drive) - (general) Have ide_raw_taskfile() copy back the taskfile after execution, otherwise we cannot use the info that ide_end_drive_cmd() puts in there. - (tcq) Use nIEN bit correctly in ide-tcq - (tcq) Small ide_tcq_wait_altstat() changes. Do initial 400ns delay (1us here), then 10us each successive run. - (tcq) Add beginning for 'nop auto poll' support check. - (tcq) Arm handler before GET_STAT() service check in ide_dma_queued_start, WD seemed to trigger interrupt before that. Makes WD Expert drives work with tcq.

Use the (well, one) standard way to build a multi-part module. Standard except for that we build aix7xxx_mod.o but then rename it at modules_install time (just as it was before).

(The O_TARGET is used only internally when linking, the name of the module is unchanged).

I'm currently working on a node affine scheduler extension for NUMA machines and the load balancer behaves a bit different from the original. So after a few boot failures with those slowly booting 16 CPU IA64 machines I thought there must be a simpler solution than synchronizing and waiting for the load balancer: just let migration_CPU0 do what it is designed for. So my proposal is: - start all migration threads on CPU#0 - initialize migration_CPU0 (trivial, reliable, as it already is on the right CPU) - let all other migration threads use set_cpus_allowed() to get to the right place The only synchronization needed is the non-zero migration threads waiting for migration_CPU0 to start working, which it will, as it is already on the right CPU. This saves quite some lines of code. I first posted this to LKML on March 6th (BTW, the fix #1, too) and since then it was tested on several big NUMA platforms: 16 CPU NEC AzusA (IA64) (also known as HP rx....), up to 32 CPU SGI IA64, 16 CPU IBM NUMA-Q (IA32). No more lock-ups at boot since then. So I consider it working. There is another good reason for this approach: the integration of the CPU hotplug patch with the new scheduler becomes easier. One just needs to create the new migration thread, it will move itself to the right CPU without any additional magic (which you otherwise need because of the synchronizations which won't be there at hotplug). Kimi Suganuma in the neighboring cube is fiddling this out currently.

Attached is a patch that disables interrupts while holding the rq_lock. This is certainly needed to prevent a race against the timer tick, as Erich Focht pointed out.

- line ending white spaces squadron strikes back; - some fscked tabs are fixed. Nice after longs coding sessions.

- dscc4_do_action() now looks like the others event waiting loops (may be called from interrupt context however); - dscc4_start_xmit(): cosmetic before LxDA changes + mb() parano; - dscc4_clock_setting(): only one return point, thanks; - dscc4_priv() invocation removed from dscc4_xxx_settings; - minor cleanups.

François Romieu authored
- DEBUG_PARANOIA was bad. "if (debug > x) {" is nice; - state_check() now has only one return point; - try_get_rx_skb() cosmetic; - dscc4_rx_update() belongs to HOLD mode to LxDA changes; - dscc4_wait_ack_cec() behaves like dscc4_xpr_ack(); - dscc4_rx_skb() refill logic is ready for LxDA mode and does everything to fulfill what its name suggests. - document some errata voodoo in dscc4_init_one(); - dscc4_init_ring() should handle try_get_rx_skb() failure.

François Romieu authored
- dscc4_patch_register() turns into scc_patchl() and should now avoid an hardware bug quoted in errata sheet; - dscc4_init_registers() interface changes as any caller doesn't really need to poke into dscc4_dev_priv internal; - scc_{writel/readl}() are added to access some buggy behaving registers; - {read/write}l conversion to the previous functions - dscc4_do_tx() sneaks, sorry. Belongs to HOLD -> LxDA changes.

This trivial patch will apply to both 2.4.19-pre7 and 2.5.8 with just line offsets. It stops us from following a NULL pointer in classzone in the case where there is a pgdat without a fully populated zone list (ie a node with no ZONE_NORMAL on an ia32 NUMA machine). Without this patch, ia32 NUMA machines won't even boot - we dereference the classzone ptr a few lines further down (or try to ;-) ).
