1. The only place that RTPRIO_TO_LOAD_WEIGHT() is used is in the call to move_tasks() in the function active_load_balance() and its purpose here is just to make sure that the load to be moved is big enough to ensure that exactly one task is moved (if there's one available). This can be accomplished by using ULONG_MAX instead and this allows RTPRIO_TO_LOAD_WEIGHT() to be deleted. 2. This, in turn, allows PRIO_TO_LOAD_WEIGHT() to be deleted. 3. This allows load_weight() to be deleted which allows TIME_SLICE_NICE_ZERO to be deleted along with the comment above it.

Marcin Slusarz reported a ne2k-pci "hung network interface" regression. delayed disable relies on the ability to re-trigger the interrupt in the case that a real interrupt happens after the software disable was set. In this case we actually disable the interrupt on the hardware level _after_ it occurred. On enable_irq, we need to re-trigger the interrupt. On i386 this relies on a hardware resend mechanism (send_IPI_self()). Actually we only need the resend for edge type interrupts. Level type interrupts come back once enable_irq() re-enables the interrupt line. I assume that the interrupt in question is level triggered because it is shared and above the legacy irqs 0-15: 17: 12 IO-APIC-fasteoi eth1, eth0 Looking into the IO_APIC code, the resend via send_IPI_self() happens unconditionally. So the resend is done for level and edge interrupts. This makes the problem more mysterious. The code in question lib8390.c does disable_irq(); fiddle_with_the_network_card_hardware() enable_irq(); The fiddle_with_the_network_card_hardware() might cause interrupts, which are cleared in the same code path again, Marcin found that when he disables the irq line on the hardware level (removing the delayed disable) the card is kept alive. So the difference is that we can get a resend on enable_irq, when an interrupt happens during the time, where we are in the disabled region.

* Fix cs5535_tuneproc() to pass PIO transfer mode value instead of PIO mode number to cs5535_set_speed() (fixes random PIO timings being programmed and a possible OOPS). Do a little cleanup while at it. * Fix cs5535_set_speed() to check if the mate device is present (fixes PIO0 taskfile timings being used if there is no other device on the cable). * Use cs5535_tuneproc() in cs5535_dma_check(). The old code had the same issue as cs5535_tuneproc() and add additionally caused 0x00-0x04 transfer mode values (== default PIO, default PIO w/ IORDY + two invalid values) being set on the device instead of values 0x08-0x0c (XFER_PIO_[0,4]).

As found by the Coverity checker, and reported by Adrian Bunk, this fixes a overrun error in the CS5535 IDE driver. Somebody got a little excited with the if() statement - the CS5535 only supports UDMA 0-4. Bart: Not a bug per se since the upper layer will never feed this function with speed > XFER_UDMA_4 (thanks to ->ultra_mask being set to 0x1f). Worth fixing anyway.

Make sure to reduce the rating of the ITC clock if ITCs are drifty. If they are drifting then we have not synchronized the ITC values, nor are we doing the jitter compensation (useless since drift may increase the differentials arbitrarily). Without this patch it is possible that the ITC clock becomes selected as the system clock on systems with drifty ITCs which will result in nanosleep hanging. One can still select the itc clock manually on such systems via clocksource=itc (Produces nice hangs on SGI Altix.)

If the sn2_rtc clock is present then it is a must have since sn2_rtc provides a synchronized time source on Altix systems. So elevate the priority to 450. Otherwise the ITC would take precendence. Altix systems currently do not boot because the ITC clocksource is broken. It seems to assume that ITCs are synchronized and as a result nanosleep hangs (may be fixed in a different patch). While we are at it: Remove the sn2_mc definition. The sn2_rtc has a fixed address. No point in reading the address from memory. Removing it avoids touching one cacheline.

* Fix MWDMA timings setup in sis_old_set_dmamode() and sis_66_set_dmamode(). The old timings were overclocked (even worse behavior than sis5513 IDE driver which depends on BIOS to program correct timings), the new timings are taken from the datasheet (they match timings from ATA spec). * Fix UDMA timings setup in sis_old_set_dmamode(). Misplaced pci_write_config_word() call resulted in UDMA timings never being set. * Fix comments for sis_133_early_set_dmamode() and sis_133_set_dmamode(): - only the former function handles early SiS 961 bridges - both functions lack MWDMA timings setup * Fix typos in sis_100_set_piomode() and sis_133_set_piomode() comments. * Bump driver version.

Linus Torvalds authored
Alexey Dobriyan noticed that the new WARN_ON() semantics that were introduced by commit 684f9783 (to also return the value to be warned on) didn't compile when given a bitfield, because the typeof doesn't work for bitfields. So instead of the typeof trick, use an "int" variable together with a "!!(x)" expression, as suggested by Al Viro. To make matters more interesting, Paul Mackerras points out that that is sub-optimal on Power, but the old asm-coded comparison seems to be buggy anyway on 32-bit Power if the conditional was 64-bit, so I think there are more problems there. Regardless, the new WARN_ON() semantics may have been a bad idea. But this at least avoids the more serious complications.
