David Abdurachmanov	d69eb98a86	riscv: fix warning in arch/riscv/include/asm/module.h ... [ Upstream commit 0138ebb90c ] Fixes warning: 'struct module' declared inside parameter list will not be visible outside of this definition or declaration Signed-off-by: David Abdurachmanov <david.abdurachmanov@gmail.com> Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Palmer Dabbelt <palmer@sifive.com> Signed-off-by: Sasha Levin <sashal@kernel.org>	2018-12-13 09:16:14 +01:00
Zong Li	b8bde0ef12	RISC-V: Add section of GOT.PLT for kernel module ... Separate the function symbol address from .plt to .got.plt section. The original plt entry has trampoline code with symbol address, there is a 32-bit padding bwtween jar instruction and symbol address. Extract the symbol address to .got.plt to reduce the module size.

Zong Li	ab1ef68e54	RISC-V: Add sections of PLT and GOT for kernel module ... The address of external symbols will locate more than 32-bit offset in 64-bit kernel with sv39 or sv48 virtual addressing. Module loader emits the GOT and PLT entries for data symbols and function symbols respectively. The PLT entry is a trampoline code for jumping to the 64-bit real address. The GOT entry is just the data symbol address. Signed-off-by: Zong Li <zong@andestech.com> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>	2018-04-02 20:00:54 -07:00
