Anup Patel	7d4420bd69	include: Extend get_insn() to read instruction from VS/VU mode ... Current implementation of get_insn() is not suitable for reading instruction from VS/VU mode because we have to set SSTATUS_MXR bit in VSSTATUS CSR for reading instruction from VS/VU mode. This patch extends get_insn() to read instruction from VS/VU mode. Signed-off-by: Anup Patel <anup.patel@wdc.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>	2019-09-30 15:35:43 +05:30
Anup Patel	a88e424f6c	lib: Handle traps when doing unpriv load/store in get_insn() ... We can get a page/access trap when doing unpriv load/store in get_insn() function because on a SMP system Linux swapper running on HART A can unmap pages from page table used by HART B. To tackle this we extend get_insn() implementation so that if we get trap in get_insn() then we redirect it to S-mode as fetch page/access fault.
