Add in code to support an 82077 FDC on sun4c systems. There is a problem with spurious interrupts but it does apear to work. Testing on my SS2 (82072A FDC) shows that the floppy driver is not 100% with sun4c any way (any spurious interrupt kills it, requiring a reboot to recover). Signed-off-by:

Don't provide fake PCI config space for sun4u. Also, put back the funny host controller space handling that at least Sabre needs. You have to read PCI host controller registers at their nature size otherwise you get zeros instead of correct values. Signed-off-by: -

Correct the Solaris x86 number of partitions (slices) is a way that is backward compatible with the earlier size. This works without a new VTOC structure definition as the timestamp and v_asciilabel fields in the VTOC are not used by the kernel yet. Signed-off-by:

Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it. As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files rebuilt down to 3444 (-12.3%).

Introduce CONFIG_SUSPEND representing the ability to enter system sleep states, such as the ACPI S3 state, and allow the user to choose SUSPEND and HIBERNATION independently of each other. Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has been chosen and the kernel is intended for SMP systems. Also, introduce CONFIG_PM_SLEEP which is automatically selected if CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the code needed for both suspend and hibernation. The top-level power management headers and the ACPI code related to suspend and hibernation are modified to use the new definitions (the changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce the number of ifdefs). There are many other files in which CONFIG_PM can be replaced with CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in the future. Signed-off-by:

A non-periodic clock_event_device and the "jiffies" clock don't mix well: tick_handle_periodic() can go into an infinite loop. Currently lguest guests use the jiffies clock when the TSC is unusable. Instead, make the Host write the current time into the lguest page on every interrupt. This doesn't cost much but is more precise and at least as accurate as the jiffies clock. It also gets rid of the GET_WALLCLOCK hypercall. Also, delay setting sched_clock until our clock is set up, otherwise the early printk timestamps can go backwards (not harmful, just ugly).

Jason Yeh sent his crashing .config: bzImages made with CONFIG_RELOCATABLE=y put the relocs where the BSS is expected, and we crash with unusual results such as: lguest: unhandled trap 14 at 0xc0122ae1 (0xa9) Relying on BSS being zero was merely laziness on my part, and unfortunately, lguest doesn't go through the normal startup path (which does this in asm).

MXC needs the same change as IOP.

In sas_smp_get_phy_events() we never test if the call to alloc_smp_req(RPEL_REQ_SIZE) succeeds or fails. That means we run the risk of dereferencing a NULL pointer if it does fail. Far better to test if we got NULL back and in that case return -ENOMEM just as we already do for the other memory allocation in that function. Signed-off-by:

BLK_DEV_BSG was added outside of the if BLOCK check, which allows it to be enabled when CONFIG_BLOCK=n. This leads to many screenlengths of errors, starting with a parse error on the request_queue_t definition.

The patch is *much* smaller than the description. I am attempting to answer to those that want to understand an issue that was reported in May this year. If a Sunrise Lake based card that requires an alternate reset mechanism is set up to ignore the commanded IOP_RESET it reports 0x00000010 (IOP_RESET ignored) instead of 0x3803000F (use alternate reset mechanism to reset all cores), and thus the reset platform function decides to switch to IOP_RESET_ALWAYS because the reset platform function parameters indicate that we *need* to reset the card. IOP_RESET_ALWAYS then responds with the 0x3803000F return code, but alas we treat this as an error instead of using the alternate reset mechanism (put a 0x03 into the register offset 0x38). The reset fails, but the fact that the IOP_RESET_ALWAYS command was issued has put the card in a purposeful shutdown state in preparation for the alternate hardware reset to be applied. Yuck. IOP_RESET is ignored in internal production cards, typically to ensure that we catch all adapter lockup issues without the driver progressing further, so this would not appear to be a field issue and thus this patch was destined to be only in the internal Adaptec source tree. IOP_RESET_ALWAYS is reserved for kexec/kdump/FirmwareUpdate/AutomatedTestFrames so we did not function as expected in any case. Also in the past we have had OEMs specifically request that cards not be resetable after a BlinkLED/FirmwareAssert for one reason or another and To head off the possibility that the Sunrise Lake based cards would suffer a similar fate, we propose the enclosed fix. Yinghai Lu of SUN had a pre-production card with IOP_RESET disabled when he reported an issue to the linux kernel list back in May regarding a kexec problem resulting from this reset being ignore. His fix was to update the Firmware to one that did not ignore the IOP_RESET. Previous kernels did not attempt to reset the adapter and that is why it surfaced as a regression in his hands. The current list of aacraid based cards that use Sunrise Lake: 9005:0285:9005:02b5 Adaptec 5445 9005:0285:9005:02b6 Adaptec 5805 9005:0285:9005:02b7 Adaptec 5085 9005:0285:9005:02c3 Adaptec 51205 9005:0285:9005:02c4 Adaptec 51605 9005:0285:9005:02ce Adaptec 51245 9005:0285:9005:02cf Adaptec 51645 9005:0285:9005:02d0 Adaptec 52445 9005:0285:9005:02d1 Adaptec 5405 9005:0285:9005:02b8 ICP ICP5445SL 9005:0285:9005:02b9 ICP ICP5085SL 9005:0285:9005:02ba ICP ICP5805SL 9005:0285:9005:02c5 ICP ICP5125SL 9005:0285:9005:02c6 ICP ICP5165SL 9005:0285:108e:7aac SUN STK RAID REM 9005:0285:108e:0286 SUN STK RAID INT 9005:0285:108e:0287 SUN STK RAID EXT 9005:0285:108e:7aae SUN STK RAID EM All of these are publicly released with IOP_RESET enabled.

Customer running an application that issues SYNCHRONIZE_CACHE calls directly noticed the broad stroke of the current implementation in the aacraid driver resulting in multiple applications feeding I/O to the storage causing the issuing application to stall for long periods of time. By only waiting for the current WRITE commands, rather than all commands, to complete; and those that are in range of the SYNCHRONIZE_CACHE call that would associate more tightly with the issuing application before telling the Firmware to flush it's dirty cache, we managed to reduce the stalling. The Firmware itself still flushes all the dirty cache associated with the array ignoring the range, it just does so in a more timely manner. Signed-off-by:
