Subject: [PATCH 0/5] Improve kernel section protections
Date: Fri,  9 Oct 2020 14:13:39 -0700	[thread overview]
Message-ID: <20201009211344.2358688-1-atish.patra@wdc.com> (raw)

This series aims at improving kernel permissions by doing following things.

1. Protect kernel sections early instead of after /init.
2. Protect .init.text & .init.data sections with appropriate permissions.
3. Move dynamic relocation section to _init.

This series is based on Guo's static object fixes[1].

Atish Patra (5):
RISC-V: Move __start_kernel to .head.text
RISC-V: Initialize SBI early
RISC-V: Enforce protections for kernel sections early
RISC-V: Protect .init.text & .init.data
RISC-V: Move dynamic relocation section under __init
