* builddeb: Add automatic support for sh{3,4}{,eb} architecturesBen Hutchings2018-07-281-3/+10
| | | | | | | | | | | | Different generations of the SH architecture are not very compatible, so there are/were separate Debian ports for SH3 and SH4. Move the fallback out of the "case" statement, so that it will also be used in case we find some SH architecture version without a known mapping.

* builddeb: Add automatic support for riscv* architecturesBen Hutchings2018-07-281-1/+1
| | | | | | | | | Debian currently only defines "riscv64", but it seems safe to assume that any 32-bit port will now be called "riscv32", also matching $UTS_MACHINE. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* builddeb: Add automatic support for sparc64 architectureBen Hutchings2018-07-281-1/+1
| | | | | | | | | We currently label 64-bit kernel packages as sparc (32-bit), mostly because it was officially supported while sparc64 was not.

| | | | | | | | | | | | | We currently label 64-bit big-endian kernel packages as powerpc (32-bit), mostly because it was officially supported while ppc64 (64-bit big-endian) was not. Now neither is officially supported, so label these packages as ppc64. Debian also has a powerpcspe (32-bit with SPE) architecture. Label packages with a suitable configuration as powerpcspe.

* builddeb: Change architecture detection fallback to use dpkg-architectureBen Hutchings2018-07-281-2/+2
| | | | | | | | | | | | We currently use dpkg --print-architecture, which reports the architecture of the build machine. We can make a better guess than this by asking dpkg-architecture what the host architecture, i.e. the default architecture for building packages, is. This is sensitive to environment variables such as CC and DEB_HOST_ARCH, which should already be set in a cross-build environment.

* kbuild: do not redirect the first prerequisite for filechkMasahiro Yamada2018-07-285-7/+7
| | | | | | | | | | | | Currently, filechk unconditionally opens the first prerequisite and redirects it as the stdin of a filechk_* rule. Hence, every target using $(call filechk,...) must list something as the first prerequisite even if it is unneeded. '< $<' is actually unneeded in most cases. Each rule can explicitly adds it if necessary. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* kbuild: if_changed: document single use per target limitationDirk Gouders2018-07-211-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Users of if_changed could easily feel invited to use it to divide a recipe into parts like: a: prereq FORCE $(call if_changed,do_a) $(call if_changed,do_b) But this is problematic, because if_changed should not be used more than once per target: in the above example, if_changed stores the command-line of the given command in .a.cmd and when a is up-to-date with respect to prereq, the file .a.cmd contains the command-line for the last command executed, i.e. do_b. When the recipe is then executed again, without any change of prerequisites, the command-line check for do_a will fail, do_a will be executed and stored in .a.cmd. The next check, however, will still see the old content (the file isn't re-read) and if_changed will skip do_b, because the command-line test will not recognize a change. On the next execution of the recipe the roles will flip: do_a is OK but do_b not and it will be executed. And so on...

* kbuild: Add build salt to the kernel and modulesLaura Abbott2018-07-184-0/+35
| | | | | | | | | | | | | | | | | | | | | In Fedora, the debug information is packaged separately (foo-debuginfo) and can be installed separately. There's been a long standing issue where only one version of a debuginfo info package can be installed at a time. There's been an effort for Fedora for parallel debuginfo to rectify this problem. Part of the requirement to allow parallel debuginfo to work is that build ids are unique between builds. The existing upstream rpm implementation ensures this by re-calculating the build-id using the version and release as a seed. This doesn't work 100% for the kernel because of the vDSO which is its own binary and doesn't get updated when embedded. Fix this by adding some data in an ELF note for both the kernel and modules. The data is controlled via a Kconfig option so distributions can set it to an appropriate value to ensure uniqueness between builds.

| | | | | | | | | | | | | | | | | | | Commit 8370edea81e3 ("bin2c: move bin2c in scripts/basic") moved bin2c to the scripts/basic/ directory, incorrectly stating "Kexec wants to use bin2c and it wants to use it really early in the build process. See arch/x86/purgatory/ code in later patches." Commit bdab125c9301 ("Revert "kexec/purgatory: Add clean-up for purgatory directory"") and commit d6605b6bbee8 ("x86/build: Remove unnecessary preparation for purgatory") removed the redundant purgatory build magic entirely.
