Replace with globally

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

Pull s390 updates from Martin Schwidefsky: "The main bulk of the s390 patches for the 4.10 merge window: - Add support for the contiguous memory allocator. - The recovery for I/O errors in the dasd device driver is improved, the driver will now remove channel paths that are not working properly. - Additional fields are added to /proc/sysinfo, the extended partition name and the partition UUID. - New naming for PCI devices with system defined UIDs. - The last few remaining alloc_bootmem calls are converted to memblock. - The thread_info structure is stripped down and moved to the task_struct. The only field left in thread_info is the flags field. - Rework of the arch topology code to fix a fake numa issue. - Refactoring of the atomic primitives and add a new preempt_count implementation. - Clocksource steering for the STP sync check offsets. - The s390 specific headers are changed to make them usable with CLANG. - Bug fixes and cleanup" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (70 commits) s390/cpumf: Use configuration level indication for sampling data s390: provide memmove implementation s390: cleanup arch/s390/kernel Makefile s390: fix initrd corruptions with gcov/kcov instrumented kernels s390: exclude early C code from gcov profiling s390/dasd: channel path aware error recovery s390/dasd: extend dasd path handling s390: remove unused labels from entry.S s390/vmlogrdr: fix IUCV buffer allocation s390/crypto: unlock on error in prng_tdes_read() s390/sysinfo: show partition extended name and UUID if available s390/numa: pin all possible cpus to nodes early s390/numa: establish cpu to node mapping early s390/topology: use cpu_topology array instead of per cpu variable s390/smp: initialize cpu_present_mask in setup_arch s390/topology: always use s390 specific sched_domain_topology_level s390/smp: use smp_get_base_cpu() helper function s390/numa: always use logical cpu and core ids s390: Remove VLAIS in ptff() and clear_table() s390: fix machine check panic stack switch ...

s390/vmlogrdr: fix IUCV buffer allocation

2016-12-12T08:01:25+00:00

The buffer for iucv_message_receive() needs to be below 2 GB. In __iucv_message_receive(), the buffer address is casted to an u32, which would result in either memory corruption or an addressing exception when using addresses >= 2 GB. Fix this by using GFP_DMA for the buffer allocation. Cc: stable@vger.kernel.org Signed-off-by: Gerald Schaefer Signed-off-by: Martin Schwidefsky

s390/smp: initialize cpu_present_mask in setup_arch

2016-12-07T06:23:07+00:00

In order to be able to setup the cpu to node mappings early it is a prerequisite to know which cpus are present. Therefore cpus must be detected much earlier than before. For sclp based cpu detection this requires yet another early sclp call, since the system is not ready to use the regular interrupt and memory allocations.

s390: char: make slp_ctl explicitly non-modular

2016-11-10T15:55:46+00:00

The Makefile currently controlling compilation of this code is obj-y, meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular usage, so that when reading the driver there is no doubt it is builtin-only. Since module_misc_device translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit.
