s390/extable: move EX_TABLE define to asm-extable.h

2022-03-07T23:33:00Z

Follow arm64 and riscv and move the EX_TABLE define to asm-extable.h which is a lot less generic than the current linkage.h. Also make sure that all files which contain EX_TABLE usages actually include the new header file. This should make sure that the files always compile and there won't be any random compile breakage due to other header file dependencies.

s390/hypfs: include z/VM guests with access control group set

2022-01-26T17:42:39Z

Currently if z/VM guest is allowed to retrieve hypervisor performance data globally for all guests (privilege class B) the query is formed in a way to include all guests but the group name is left empty. This leads to that z/VM guests which have access control group set not being included in the results (even local vm). Change the query group identifier from empty to "any" to retrieve information about all guests from any groups (or without a group set).

s390: rename dma section to amode31

2021-08-05T12:10:53Z

The dma section name is confusing, since the code which resides within that section has nothing to do with direct memory access. Instead the limitation is that the code has to run in 31 bit addressing mode, and therefore has to reside below 2GB. So the name was chosen since ZONE_DMA is the same region. To reduce confusion rename the section to amode31, which hopefully describes better what this is about. Note: this will also change vmcoreinfo strings - SDMA=... gets renamed to SAMODE31=... - EDMA=... gets renamed to EAMODE31=...

s390: replace deprecated CPU-hotplug functions

2021-08-05T12:10:53Z

The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock(). Replace deprecated CPU-hotplug functions with the official version. The behavior remains unchanged.

s390/hypfs: use store_tod_clock_ext()

2021-02-13T16:17:55Z

Use store_tod_clock_ext() instead of get_tod_clock_ext(). Unfortunately one usage has to be converted to a cast, since otherwise a uapi header file would have to be changed. Signed-off-by: Heiko Carstens Signed-off-by: Vasily Gorbik

2019-09-24T19:33:34Z

Pull more mount API conversions from Al Viro: "Assorted conversions of options parsing to new API. gfs2 is probably the most serious one here; the rest is trivial stuff. Other things in what used to be #work.mount are going to wait for the next cycle (and preferably go via git trees of the filesystems involved)" * 'work.mount3' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: gfs2: Convert gfs2 to fs_context vfs: Convert spufs to use the new mount API vfs: Convert hypfs to use the new mount API hypfs: Fix error number left in struct pointer member vfs: Convert functionfs to use the new mount API vfs: Convert bpf to use the new mount API

vfs: Convert hypfs to use the new mount API

2019-09-19T02:44:02Z

Convert the hypfs filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information.
