Change the way how pgd_offset, p4d_offset, pud_offset and pmd_offset walk the page tables. pgd_offset now always calculates the index for the top-level page table and adds it to the pgd, this is either a segment table offset for a 2-level setup, a region-3 offset for 3-levels, region-2 offset for 4-levels, or a region-1 offset for a 5-level setup. The other three functions p4d_offset, pud_offset and pmd_offset will only add the respective offset if they dereference the passed pointer. With the new way of walking the page tables a sequence like this from mm/gup.c now works: pgdp = pgd_offset(current->mm, addr); pgd = READ_ONCE(*pgdp); p4dp = p4d_offset(&pgd, addr); p4d = READ_ONCE(*p4dp); pudp = pud_offset(&p4d, addr); pud = READ_ONCE(*pudp); pmdp = pmd_offset(&pud, addr); pmd = READ_ONCE(*pmdp); Signed-off-by:

qdio.ko offers a small number of high-level functions to drive the scanning of a QDIO queue for ready-to-process SBALs: qdio_get_next_buffers(), __[ti]qdio_inbound_processing() and __qdio_outbound_processing(). Let each of those functions maintain the 'start' index for their current scan, and pass it to lower-level helpers as needed. This improves the code's overall layering, and allows us to eliminate the additional first_to_kick cursor with a follow-on patch. Signed-off-by:

llvm on s390 has problems with __builtin_return_address(n), with n>0, this results in a somewhat cryptic error message: fatal error: error in backend: Unsupported stack frame traversal count To work around it, use the direct return address directly. This is probably not ideal here, but gets things to compile and should only lead to inferior reporting, not to misbehavior of the generated code.

This cursor is used for debugging only. But since commit "s390/qdio: pass up count of ready-to-process SBALs" it effectively duplicates the first_to_check cursor, diverging for just a short moment when get_*_buffer_frontier() updates q->first_to_check. Signed-off-by:
-
Julian Wiedmann authored
When passing a range of ready-to-process SBALs to the upper-layer driver, use the available 'count' instead of calculating the distance between the first_to_check and first_to_kick cursors. This simplifies the logic of the queue-scan path, and opens up the possibility of scanning all 128 SBALs in one go (as determining the reported count no longer requires wrap-around safe arithmetic on the queue's cursors). Signed-off-by:

Julian Wiedmann authored
When qdio_{in,out}bound_q_moved() scans a queue for pending work, it currently only returns a boolean to its caller. The interface to the upper-layer-drivers (qdio_kick_handler() and qdio_get_next_buffers()) then re-calculates the number of pending SBALs from the q->first_to_check and q->first_to_kick cursors. Refactor this so that whenever get_{in,out}bound_buffer_frontier() adjusted the queue's first_to_check cursor, it also returns the corresponding count of ready-to-process SBALs (and 0 else). A subsequent patch will then make use of this additional information. Signed-off-by: -

The DSCI is a 1-byte field, placed at the start of an u32. So when printing it to a queue's debug state, limit the output to the part that's actually occupied by the DSCI. When the DSCI is set this gives us the expected output of '1', rather than the current (obscure) value of '16777216'. Suggested-by:

The Ultravisor Call Facility (stfle bit 158) defines an API to the Ultravisor (UV calls), a mini hypervisor located at machine level. With help of the Ultravisor, KVM will be able to run "protected" VMs, special VMs whose memory and management data are unavailable to KVM. The protected VMs can also request services from the Ultravisor. The guest api consists of UV calls to share and unshare memory with the kvm hypervisor. To enable this feature support PROTECTED_VIRTUALIZATION_GUEST kconfig option has been introduced. Co-developed-by:

Introduce .boot.preserve.data section which is similar to .boot.data and "shared" between the decompressor code and the decompressed kernel. The decompressor will store values in it, and copy over to the decompressed image before starting it. This method allows to avoid using pre-defined addresses and other hacks to pass values between those boot phases. Unlike .boot.data section .boot.preserved.data is NOT a part of init data, and hence will be preserved for the kernel life time. Signed-off-by:

The DASD driver incorrectly limits the maximum number of blocks of ECKD DASD volumes to 32 bit numbers.

The marshalling of AFS.StoreData, AFS.StoreData64 and YFS.StoreData64 calls generated by ->setattr() ops for the purpose of expanding a file is incorrect due to older documentation incorrectly describing the way the RPC 'FileLength' parameter is meant to work. The older documentation says that this is the length the file is meant to end up at the end of the operation; however, it was never implemented this way in any of the servers, but rather the file is truncated down to this before the write operation is effected, and never expanded to it (and, indeed, it was renamed to 'TruncPos' in 2014). Fix this by setting the position parameter to the new file length and doing a zero-lengh write there. The bug causes Xwayland to SIGBUS due to unexpected non-expansion of a file it then mmaps. This can be tested by giving the following test program a filename in an AFS directory: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <fcntl.h> #include <sys/mman.h> int main(int argc, char *argv[]) { char *p; int fd; if (argc != 2) { fprintf(stderr, "Format: test-trunc-mmap <file>\n"); exit(2); } fd = open(argv[1], O_RDWR | O_CREAT | O_TRUNC); if (fd < 0) { perror(argv[1]); exit(1); } if (ftruncate(fd, 0x140008) == -1) { perror("ftruncate"); exit(1); } p = mmap(NULL, 4096, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); if (p == MAP_FAILED) { perror("mmap"); exit(1); } p[0] = 'a'; if (munmap(p, 4096) < 0) { perror("munmap"); exit(1); } if (close(fd) < 0) { perror("close"); exit(1); } exit(0); } Fixes: 31143d5d ("AFS: implement basic file write support") Reported-by:Jonathan Billings <jsbillin@umich.edu> Tested-by:
