2017-08-03s390/sclp: add const to bin_attribute structureBhumika Goyal1-1/+1
Declare bin_attribute structure as const as it is only passed as an argument to the function sysfs_create_bin_file. This argument is of type const, so declare the structure as const. Cross compiled for s390 architecture. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2017-08-03s390: use generic uapi/asm/swab.hHeiko Carstens2-89/+1
clang doesn't like s390 specific inline assembler constraints. These are present in our arch specific uapi/asm/swab.h which again is required by some ebpf test cases. For current compiler versions the generic swab.h already makes use of gcc's builtin functions. Therefore we can simply remove our own header file and use the generic one. This will generate worse code if used with compilers before gcc 4.8, which has no __builtin_bswap16(); or before gcc v4.4, which has no __builtin_bswap[32|64](). For these cases a C implementation fallback would be used which generates more code, but is still correct (170KB extra code for gcc 4.3 with performance_defconfig). However given that we need (and want) to get rid of the inline assemblies anyway in order to be able to use clang, the above is just a minor drawback if old gcc compilers are used. With current compilers there is close to zero difference, except for three btrfs bit functions which generate more out-of-line code. The generated code looks still correct and also uses the s390 specific byteswap instructions.

2017-07-26s390/spinlock: add niai spinlock hintsMartin Schwidefsky2-40/+56
The z14 machine introduces new mode of the next-instruction-access-intent NIAI instruction. With NIAI-8 it is possible to pin a cache-line on a CPU for a small amount of time, NIAI-7 releases the cache-line again. Finally NIAI-4 can be used to prevent the CPU to speculatively access memory beyond the compare-and-swap instruction to get the lock. Use these instruction in the spinlock code.

2017-07-26s390/time: add support for the TOD clock epoch extensionMartin Schwidefsky12-62/+130
The TOD epoch extension adds 8 epoch bits to the TOD clock to provide a continuous clock after 2042/09/17. The store-clock-extended (STCKE) instruction will store the epoch index in the first byte of the 16 bytes stored by the instruction. The read_boot_clock64 and the read_presistent_clock64 functions need to take the additional bits into account to give the correct result after 2042/09/17. The clock-comparator register will stay 64 bit wide. The comparison of the clock-comparator with the TOD clock is limited to bytes 1 to 8 of the extended TOD format. To deal with the overflow problem due to an epoch change the clock-comparator sign control in CR0 can be used to switch the comparison of the 64-bit TOD clock with the clock-comparator to a signed comparison. The decision between the signed vs. unsigned clock-comparator comparisons is done at boot time. Only if the TOD clock is in the second half of a 142 year epoch the signed comparison is used. This solves the epoch overflow issue as long as the machine is booted at least once in an epoch. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

The ESSA instruction has a new option that allows to tag pages that are not used as a page table. Without the tag the hypervisor has to assume that any guest page could be used in a page table inside the guest. This forces the hypervisor to flush all guest TLB entries whenever a host page table entry is invalidated. With the tag the host can skip the TLB flush if the page is tagged as normal page.

2017-07-24vfio: ccw: fix bad ptr math for TIC cda translationJason J. Herne1-1/+1
When we are translating channel data addresses from guest to host address space for TIC instructions we are getting incorrect addresses because of a pointer arithmetic error. We currently calculate the offset of the TIC's cda from the start of the channel program chain (ccw->cda - ccw_head). We then add that to the address of the ccw chain in host memory (iter->ch_ccw). The problem is that iter->ch_ccw is a pointer to struct ccw1 so when we increment it we are actually incrementing by the size of struct ccw1 which is 8 bytes. The intent was to increment by n-bytes, not n*8. The fix: cast iter->ch_ccw to char* so it will be incremented by n*1. Reviewed-by: Dong Jia Shi <bjsdjshi@linux.vnet.ibm.com> Signed-off-by: Jason J.

When setting up the Xenstore watch for the memory target size the new watch will fire at once. Don't try to reach the configured target size by onlining new memory in this case, as the current memory size will be smaller in almost all cases due to e.g. BIOS reserved pages. Onlining new memory will lead to more problems e.g. undesired conflicts with NVMe devices meant to be operated as block devices. Instead remember the difference between target size and current size when the watch fires for the first time and apply it to any further size changes, too.
