Message-Id: <1446582059-17355-4-git-send-email-octavian.purdila@intel.com>
Date: Tue, 3 Nov 2015 22:20:34 +0200
From: Octavian Purdila <octavian.purdila@...el.com>

Subject: [RFC PATCH 03/28] lkl: architecture skeleton for Linux kernel library
Adds the LKL Kconfig, vmlinux linker script, basic architecture
headers and miscellaneous basic functions or stubs such as
dump_stack(), show_regs() and cpuinfo proc ops.
The headers we introduce in this patch are simple wrappers to the
asm-generic headers or stubs for things we don't support, such as
ptrace, DMA, signals, ELF handling and low level processor operations.
The kernel configuration is automatically updated to reflect the
endianness of the host, 64bit support or the output format for
vmlinux's linker script. We do this by looking at the ld's default
output format.
