mm: remove include/linux/bootmem.h

Move remaining definitions and declarations from include/linux/bootmem.h into include/linux/memblock.h and remove the redundant header.

s390: drivers: Remove redundant license text

2017-11-24T13:28:47Z

Now that the SPDX tag is in all drivers/s390/ files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

s390: cio: add SPDX identifiers to the remaining files

2017-11-24T13:28:41Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/s390/cio/ files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

s390/cmf: avg_utilization

2017-09-28T05:29:42Z

All (but one) cmf related sysfs attributes have been converted to read directly from the measurement block using cmf_read. This is not possible for the avg_utilization attribute since this is an aggregation of several values for which cmf_read only returns average values. Move the computation of the utilization value to the cmf_read interface such that it can use the raw data.

s390/cmf: read from hw buffer

2017-09-28T05:29:42Z

To ensure data consistency when reading from the channel measurement block we wait for the subchannel to become idle and copy the whole block. This is unnecessary when all we do is export the individual values via sysfs. Read the values for sysfs export directly from the measurement block.

s390/cmf: simplify copy_block

2017-09-28T05:29:42Z

cmf_copy_block tries to ensure data consistency by copying the channel measurement block twice and comparing the data. This was needed on very old machines only. Nowadays we guarantee consistency by copying the data when the channel is idle. Signed-off-by: Sebastian Ott Reviewed-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky
