Subject: ARM: tegra: solve adr range issue with THUMB2_KERNEL enabled
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c312908a10677cc866b2473f4f3fabb448bdfb64;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: tegra: solve adr range issue with THUMB2_KERNEL enabled

When building the kernel with CONFIG_THUMB2_KERNEL enabled, older
assemblers may emit the following error:

reset-handler.S:78: Error: invalid immediate for address calculation (value = 0x00000004)

Using an explicit adr.w instruction will solve this. Newer assemblers do
this automatically. Use the W() macro to do this under Thumb mode only.
