2019-08-10kbuild: show hint if subdir-y/m is used to visit module MakefileMasahiro Yamada
Since commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod"), a module is no longer built in the following pattern: [Makefile] subdir-y := some-module [some-module/Makefile] obj-m := some-module.o You cannot write Makefile this way in upstream because modules.order is not correctly generated. subdir-y is used to descend to a sub-directory that builds tools, device trees, etc. For external modules, the modules order does not matter. So, the Makefile above was known to work. I believe the Makefile should be re-written as follows: [Makefile] obj-m := some-module/ [some-module/Makefile] obj-m := some-module.o However, people will have no idea if their Makefile suddenly stops working. In fact, I received questions from multiple people. Show a warning for a while if obj-m is specified in a Makefile visited by subdir-y or subdir-m. I touched the %/ rule to avoid false-positive warnings for the single target.

2019-08-10kbuild: generate modules.order only in directories visited by obj-y/mMasahiro Yamada
The modules.order files in directories visited by the chain of obj-y or obj-m are merged to the upper-level ones, and become parts of the top-level modules.order. On the other hand, there is no need to generate modules.order in directories visited by subdir-y or subdir-m since they would become orphan anyway.

2019-08-10kbuild: fix false-positive need-builtin calculationMasahiro Yamada
The current implementation of need-builtin is false-positive, for example, in the following Makefile: obj-m := foo/ obj-y := foo/bar/ ..., where foo/built-in.a is not required. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-08-10kbuild: revive single target %.koMasahiro Yamada
I removed the single target %.ko in commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod") because the modpost stage does not work reliably. For instance, the module dependency, modversion, etc. do not work if we lack symbol information from the other modules. Yet, some people still want to build only one module in their interest, and it may be still useful if it is used within those limitations.

2019-08-09gfs2: gfs2_walk_metadata fixAndreas Gruenbacher
It turns out that the current version of gfs2_metadata_walker suffers from multiple problems that can cause gfs2_hole_size to report an incorrect size. This will confuse fiemap as well as lseek with the SEEK_DATA flag. Fix that by changing gfs2_hole_walker to compute the metapath to the first data block after the hole (if any), and compute the hole size based on that. Fixes xfstest generic/490.

s390 does not map the vdso for statically linked binaries, assuming that this doesn't make sense. See commit fc5243d98ac2 ("[S390] arch_setup_additional_pages arguments"). However with glibc commit d665367f596d ("linux: Enable vDSO for static linking as default (BZ#19767)") and commit 5e855c895401 ("s390: Enable VDSO for static linking") the vdso is also used for statically linked binaries - if the kernel would make it available. Therefore map the vdso always, just like all other architectures.

2019-08-09KVM: arm/arm64: vgic: Reevaluate level sensitive interrupts on enableAlexandru Elisei
A HW mapped level sensitive interrupt asserted by a device will not be put into the ap_list if it is disabled at the VGIC level. When it is enabled again, it will be inserted into the ap_list and written to a list register on guest entry regardless of the state of the device. We could argue that this can also happen on real hardware, when the command to enable the interrupt reached the GIC before the device had the chance to de-assert the interrupt signal; however, we emulate the distributor and redistributors in software and we can do better than that.

2019-08-09KVM: arm: Don't write junk to CP15 registers on resetMarc Zyngier
At the moment, the way we reset CP15 registers is mildly insane: We write junk to them, call the reset functions, and then check that we have something else in them. The "fun" thing is that this can happen while the guest is running (PSCI, for example). If anything in KVM has to evaluate the state of a CP15 register while junk is in there, bad thing may happen. Let's stop doing that. Instead, we track that we have called a reset function for that register, and assume that the reset function has done something. In the end, the very need of this reset check is pretty dubious, as it doesn't check everything (a lot of the CP15 reg leave outside of the cp15_regs[] array). It may well be axed in the near future.
