Subject: x86/unwind: Prepend hex mask value with '0x' in unwind_dump()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4ea3d7410c3597910071182a6bc258c015942887;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86/unwind: Prepend hex mask value with '0x' in unwind_dump()

In unwind_dump(), the stack mask value is printed in hex, but is
confusingly not prepended with '0x'.
