Subject: [PATCH v8 05/11] arm: processor.h: add definition for immediate value mask
Date: Tue, 10 Oct 2017 18:52:45 +0300	[thread overview]
Message-ID: <1507650771-16631-6-git-send-email-volodymyr_babchuk@epam.com> (raw)
In-Reply-To: <1507650771-16631-1-git-send-email-volodymyr_babchuk@epam.com>

This patch defines HSR_XXC_IMM_MASK. It can be used to extract
immediate value for trapped HVC32, HVC64, SMC64, SVC32, SVC64
instructions, as described in the ARM ARM
(ARM DDI 0487B.a pages D7-2270, D7-2272).
