Subject: [SPARC64]: bp->pil can never be zero
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6a76267f0e52d920e6bb6da75541e6116d7304da;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[SPARC64]: bp->pil can never be zero

Only pil0_dummy_bucket had a pil of zero and we just killed that
off, so we can delete all special case code that used bp->pil==0
as a way to identify a dummy bucket.
