2019-04-01PCI: mediatek: Fix a leaked reference by adding missing of_node_put()Wen Yang1-0/+1
The call to of_get_next_child() returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. irq_domain_add_linear() also calls of_node_get() to increase refcount, so irq_domain will not be affected when it is released. Detected by coccinelle with the following warnings: ./drivers/pci/controller/pcie-mediatek.c:577:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 567, but without a corresponding object release within this function. ./drivers/pci/controller/pcie-mediatek.c:583:3-9: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 567, but without a corresponding object release within this function. ./drivers/pci/controller/pcie-mediatek.c:586:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 567, but without a corresponding object release within this function.

The call to of_parse_phandle() returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. iproc_msi_init() also calls of_node_get() to increase refcount: proc_msi_init() -> iproc_msi_alloc_domains() -> pci_msi_create_irq_domain() -> msi_create_irq_domain() -> irq_domain_create_linear() -> __irq_domain_add() so irq_domain will not be affected when it is released.

2019-03-17kbuild: force all architectures except um to include mandatory-yMasahiro Yamada29-47/+18
Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes the common Kbuild.asm file. Factor out the duplicated include directives to scripts/Makefile.asm-generic so that no architecture would opt out of the mandatory-y mechanism. um is not forced to include mandatory-y since it is a very exceptional case which does not support UAPI.

This reverts commit caf6fe91ddf62a96401e21e9b7a07227440f4185. The commit was fine but is no longer needed as of commit 3a2429e1faf4 ("kbuild: change if_changed_rule for multi-line recipe"). Let's go back to using ";" to be consistent.

2019-03-17kbuild: Make NOSTDINC_FLAGS a simply expanded variableDouglas Anderson1-1/+1
During a simple no-op (nothing changed) build I saw 39 invocations of the C compiler with the argument "-print-file-name=include". We don't need to call the C compiler 39 times for this--one time will suffice. Let's change NOSTDINC_FLAGS to a simply expanded variable to avoid this since there doesn't appear to be any reason it should be recursively expanded. On my build this shaved ~400 ms off my "no-op" build. Note that the recursive expansion seems to date back to the (really old) commit e8f5bdb02ce0 ("[PATCH] Makefile include path ordering"). It's a little unclear to me if the point of that patch was to switch the variable to be recursively expanded (which it did) or to avoid directly assigning to NOSTDINC_FLAGS (AKA to switch to +=) because someone else (out of tree?) was setting it. I presume later since if the only goal was to switch to recursive expansion the patch would have just removed the ":".

2019-03-17kbuild: deb-pkg: avoid implicit effectsArseny Maslennikov1-1/+4
* The man page for dpkg-source(1) notes: > -b, --build directory [format-specific-parameters] > Build a source package (--build since dpkg 1.17.14). > <...> > > dpkg-source will build the source package with the first > format found in this ordered list: the format indicated > with the --format command line option, the format > indicated in debian/source/format, “1.0”. The fallback > to “1.0” is deprecated and will be removed at some point > in the future, you should always document the desired > source format in debian/source/format. See section > SOURCE PACKAGE FORMATS for an extensive description of > the various source package formats. Thus it would be more foolproof to explicitly use 1.0 (as we always did) than to rely on dpkg-source's defaults. * In a similar vein, debian/rules is not made executable by mkdebian, and dpkg-source warns about that but still silently fixes the file.
