The planned move of include/asm-s390 to arch/s390/include/asm requires that all includes for asm headers use include/asm and not include/asm-s390. Signed-off-by:Martin Schwidefsky <schwidefsky@de.ibm.com>

Since git commit 3da1c84c "workqueues: make get_online_cpus() useable for work->func()" it is safe to call get_online_cpus() from workqueue context. So remove the kthread workaround again. Signed-off-by:

Fix these two false positive warnings: WARNING: vmlinux.o(.text+0x2e1cc4): Section mismatch in reference from the function s390_virtio_console_init() to the function .init.text:early_put_chars() The function s390_virtio_console_init() references the function __init early_put_chars(). This is often because s390_virtio_console_init lacks a __init annotation or the annotation of early_put_chars is wrong. WARNING: vmlinux.o(.text+0x2e1cd0): Section mismatch in reference from the function s390_virtio_console_init() to the function .init.text:virtio_cons_early_init() The function s390_virtio_console_init() references the function __init virtio_cons_early_init().

Fix the two section mismatch warnings below. This fixes two real bugs since the code which has __exit annotations may already be gone when it is called. WARNING: vmlinux.o(.init.text+0x1cc4a): Section mismatch in reference from the function init_QDIO() to the function .exit.text:qdio_setup_exit() The function __init init_QDIO() references a function __exit qdio_setup_exit(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of qdio_setup_exit() so it may be used outside an exit section. WARNING: vmlinux.o(.init.text+0x1cc7a): Section mismatch in reference from the function init_QDIO() to the function .exit.text:qdio_remove_perf_stats() The function __init init_QDIO() references a function __exit qdio_remove_perf_stats(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of qdio_remove_perf_stats() so it may be used outside an exit section. Signed-off-by:

Fix these two (false positive) warnings by adding an __init annoation: WARNING: vmlinux.o(.text+0x7e6a): Section mismatch in reference from the function stp_reset() to the function .init.text:__alloc_bootmem() The function stp_reset() references the function __init __alloc_bootmem(). This is often because stp_reset lacks a __init annotation or the annotation of __alloc_bootmem is wrong. WARNING: vmlinux.o(.text+0x7ece): Section mismatch in reference from the function stp_reset() to the function .init.text:free_bootmem() The function stp_reset() references the function __init free_bootmem(). This is often because stp_reset lacks a __init annotation or the annotation of free_bootmem is wrong. Signed-off-by:

For anonymous pages without a swap cache backing the check in page_remove_rmap for the physical dirty bit in page_remove_rmap is unnecessary. The instructions that are used to check and reset the dirty bit are expensive. Removing the check noticably speeds up process exit. In addition the clearing of the dirty bit in __SetPageUptodate is pointless as well. With these two changes there is no storage key operation for an anonymous page anymore if it does not hit the swap space. The micro benchmark which repeatedly executes an empty shell script gets about 5% faster. Signed-off-by: -

sclp_sync_wait wait synchronously for an sclp interrupt and disables timer interrupts. However on the irq enter paths there is an extra check if a timer interrupt would be due and calls the timer callback. This would schedule softirqs in the wrong context. So introduce local_tick_enable/disable which prevents this. Signed-off-by:

During startup we check if diag308 works using diag 308 subcode 6, which stores the actual ipl information. This fails with rc = 0x102, if the system has been ipled from the HMC using load from CD or load from file. In the case of rc = 0x102 we have to assume that diag 308 is working, since it still can be used to ipl from an alternative device. Signed-off-by:

When z/VM provides two virtual devices (minidisks) that reside on the same real device, both will receive the configuration data from the real device and thus get the same uid. To fix this problem, z/VM provides an additional configuration data record that allows to distinguish between minidisks. z/VM APAR VM64273 needs be installed so this fix has an effect. Signed-off-by:

The iov_iter_advance() function would look at the iov->iov_len entry even though it might have iterated over the whole array, and iov was pointing past the end. This would cause DEBUG_PAGEALLOC to trigger a kernel page fault if the allocation was at the end of a page, and the next page was unallocated. The quick fix is to just change the order of the tests: check that there is any iovec data left before we check the iov entry itself. Thanks to Alexey Dobriyan for finding this case, and testing the fix. Reported-and-tested-by:

We zero-fill them like we are supposed to, and that's all fine. It's only an error if the 'romfs_copyfrom()' routine isn't able to fill the data that is supposed to be there. Most of the patch is really just re-organizing the code a bit, and using separate variables for the error value and for how much of the page we actually filled from the filesystem.

The new kgdb architecture specific handler registers and unregisters dynamically for exceptions depending on when you configure a kgdb I/O driver. Aside from initializing the exceptions earlier in the boot process, kgdb should have no impact on a device when it is compiled in so long as an I/O module is not configured for use. There have been quite a number of contributors during the existence of this patch (see arch/mips/kernel/kgdb.c). Most recently Jason re-wrote the mips kgdb logic to use the die notification handlers.

An earlier update changed some calls from simple_strotl to strict_strtol but did not account for the differences in the syntax between the calls. simple_strotl returns the integer; strict_strtol returns an error code and takes a pointer to the result. As it was, NULL was being passed in place of the result, which led to failures during kernel initialization when using YAMON. Signed-off-by:
