| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | atomic_notifier_chain_register() and uml_postsetup() do call kernel code that rely on the "current" kernel macro and a valid task_struct resp. thread_info struct. Give those functions a valid stack by moving uml_postsetup() in the init_thread stack. This moves enables a panic() call in this early code to generate a valid stacktrace, instead of crashing. E.g. when an UML kernel is started with an initrd but too few physical memory the panic() call get's actually processed.

This an enables the printing of early panic() calls triggered in uml_postsetup(). When a panic() call happens so early in the UML kernel no earlyprintk/console is available yet, but with a kmsg_dumper in place the kernel message buffer will be outputted to the user, to give a better hint, of what the failure was.

| * | x86, UML: fix integer overflow in ELF_ET_DYN_BASEAndrey Ryabinin2015-04-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Almost all arches define ELF_ET_DYN_BASE as 2/3 of TASK_SIZE. Though it seems that some architectures do this in a wrong way. The problem is that 2*TASK_SIZE may overflow 32-bits so the real ELF_ET_DYN_BASE becomes wrong. Fix this overflow by dividing TASK_SIZE prior to multiplying: (TASK_SIZE / 3 * 2) Signed-off-by: Andrey Ryabinin <a.ryabinin@samsung.com> Signed-off-by: Richard Weinberger <richard@nod.at>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before we had SKAS0 UML had two modes of operation TT (tracing thread) and SKAS3/4 (separated kernel address space). TT was known to be insecure and got removed a long time ago. SKAS3/4 required a few (3 or 4) patches on the host side which never went mainline. The last host patch is 10 years old. With SKAS0 mode (separated kernel address space using 0 host patches), default since 2005, SKAS3/4 is obsolete and can be removed. Signed-off-by: Richard Weinberger <richard@nod.at>

Unfortunately, I could not come up with a way to make the Kconfig symbol depend on the binutils version, which would be the nicest solution. Instead, this patch uses the 'as-instr' Kbuild macro to find out whether the support is present in the assembler, and otherwise emits a non-fatal warning indicating which selected modules could not be built.

| * | | | | | crypto: arm/sha256 - avoid sha256 code on ARMv7-MArnd Bergmann2015-04-131-0/+1

Enabling it in an ARMv7-M kernel results in this build failure: arm-linux-gnueabi-ld: error: arch/arm/crypto/sha256_glue.o: Conflicting architecture profiles M/A arm-linux-gnueabi-ld: failed to merge target specific data of file arch/arm/crypto/sha256_glue.o This adds a Kconfig dependency to prevent the code from being disabled for ARMv7-M.
