Just copy the first 512 read-only bytes of the current cpu lowcore if a new cpu gets onlined. The rest is zeroed out and must be explicitly initialized. Current code just copies the entire lowcore and initializes the needed fields. This should reveal bugs in future enhancements quite early. Also when the lowcore of the first cpu is replaced this is now done atomically (no interrupts, no machine checks).

After setting the status of the cqr and releasing the lock for the block cqr queue, we call the cqr callback function, which will usually just trigger the dasd_block_tasklet. But when the tasklet is already running the cqr might be processed before we invoke the callback function. In rare cases the callback pointer may already be invalid by the time we want to call it, which will result in a panic. Solution: Call the callback function first and then release the lock.

If both NO_IDLE_HZ and VIRT_TIMER are disabled default_idle won't load an enabled wait psw and busy loop instead. This is because the idle_chain is empty and the return value of atomic_notifier_call_chain will be NOTIFY_DONE, which causes default_idle to return instead of loading an enabled wait psw. Fix this by calling __atomic_notifier_call_chain instead and add proper return value handling.

This patch fixes the missing residual count setting in DMA mode, which was introduced during the conversion to blk-end-request. The residual count could be used by the request submitter. So if it isn't set correctly, some upper layers does not work. (e.g. wodim for CD burning.) The bug is in only DMA mode. In PIO mode, we are setting the residual count correctly, so no need to fix.

Prefetch needs to be set for some ide devices to work when connected to a ht6560b interface. This was not always done properly, causing a system with a HD and CD on the primary interface to not work properly. Or, in effect, hang hard. This patch forces prefetch on devices before checking whether it is necessary to change the settings in the interface This patch should also be applied to 2.4. I don't currently have a 2.4 tree around.

The early boot code maps KERNEL_TEXT_SIZE (currently 40MB) starting from __START_KERNEL_map. The kernel itself only needs _text to _end mapped in the high alias. On relocatible kernels the ASM setup code adjusts the compile time created high mappings to the relocation. This creates invalid pmd entries for negative offsets: 0xffffffff80000000 -> pmd entry: ffffffffff2001e3 It points outside of the physical address space and is marked present. This starts at the virtual address __START_KERNEL_map and goes up to the point where the first valid physical address (0x0) is mapped. Zap the mappings before _text and after _end right away in early boot. This removes also the invalid entries. Furthermore it simplifies the range check for high aliases.

In nes_create_qp(), the test if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) { is used to error out if the db_index is too large; however, if the test doesn't trigger, then the index is used as nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp; and mmap_nesqp is declared as struct nes_qp *mmap_nesqp[NES_MAX_USER_WQ_REGIONS]; which leads to an array overrun if the index is exactly equal to NES_MAX_USER_WQ_REGIONS. Fix this by bailing out if the index is greater than or equal to NES_MAX_USER_WQ_REGIONS. This was spotted by the Coverity checker (CID 2162).
