LLDDs should never see REQ_BLOCK_PC requests, we can handle them just fine in the core code. There is a small behaviour change in that some check in sr's rw_intr are bypassed, but I consider the old behaviour a bug. Mike found this cleanup opportunity and provdided early patches, so all the credit goes to him, even if I redid the patches from scratch beause that was easier than forward-porting the old patches.

We need to iterate over all children when removing and expander, else stale objects will be around after host removal. This fixes the oops Eric Moore saw when removing and reloading mptsas. Also don't try the scsi_remove_target call unless operating on an end device. The current unconditional call is harmless but confusing. Signed-off-by:

While trying to get SUSE's SLES9 working on system with more than 4GB we've noticed that SCSI layer happilly passes addresses over 4GB to the buslogic driver, which is quite a big problem as buslogic can generate only 32bit busmastering cycles. Fortunately in the current kernels this problem does not exist anymore as SCSI layer now assumes 4GB capable device by default, but it is still good idea to pass correct device structure to the SCSI layer. If nothing else, /sys/block/sda/device now points to /sys/devices/pci0000:00/0000:00:10.0/host0/... instead of /sys/devices/platform/host0/... like it did in the past. Change does nothing for ISA based BusLogic adapters, they'll still end under platform (and they are probably broken for long time as I do not see anything forcing ISA 16MB limit for them).

Received From Mark Salyzyn. The Jaguar and Corsair class of adapters (2410, 2810, 2610, 21610, CERC) perform better (about 10% better read performance, write performance neutral) with current Firmware if the OS limits the number of scatter gather elements to 17 per request. Signed-off-by:

The driver is doing a rather stupid mod_timer allegedly to "give request sense more time to complete". This is illegal and pointless, so just eliminate it. Also eliminate all the other uses of struct timer_list in the driver, which are mostly bogus. Signed-off-by: -

o This fix was posted for i386 long back. Posting it for x86_64. http://marc.theaimsgroup.com/?l=linux-kernel&m=110380103229830&w=2 o This patch fixes the problem of secondary cpus boot up. This situation is faced when kernel is built for default locations like 16MB and onwards. In this configuration, only primary cpu (BP) comes and secondary cpus don't boot. o Problem occurs because in trampoline code, lgdt is not able to load the GDT as it happens to be situated beyond 16MB. This is due to the fact that cpu is still in real mode and default operand size is 16bit. o This patch uses lgdtl instead of lgdt to force operand size to 32 instead of 16. Signed-off-by:

Previously they would be only allocated before the kernel text at 1MB. This limited the maximum supported memory to 128GB. Now allow the e820 allocator to put them everywhere. Try to put them beyond any DMA zones to avoid filling them up. This should free some GFP_DMA memory compared to earlier kernels. Signed-off-by:

When building in a separate objtree, file names produced by BUG() & Co. can get fairly long; printing only the first 50 characters may thus result in (almost) no useful information. The following change makes it so that rather the last 50 characters of the filename get printed. Signed-Off-By:

Due to a broken condition, the body of the loop that is intended to wait for the Update-In-Progress bit to get set and then cleared again was never entered; in fact, the entire loop was optimized out by the compiler. Here is a change to fix the condition (and to also move the initialization of locals out of the spin lock protected region). Signed-Off-By:

o Currently, during kexec reboot, IOAPIC is re-programmed back to virtual wire mode if there was an i8259 connected to it. This enables getting timer interrupts in second kernel in legacy mode. o After putting into virtual wire mode, IOAPIC delivers the i8259 interrupts to CPU0. This works well for kexec but not for kdump as we might crash on a different CPU and second kernel will not see timer interrupts. o This patch modifies the redirection table entry to deliver the timer interrupts to the cpu we are rebooting (instead of hardcoding to zero). This ensures that second kernel receives timer interrupts even on a non-boot cpu. Signed-off-by:
