Subject: vmalloc: call flush_cache_vunmap() from unmap_kernel_range()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=734269521e320ad14ed39ae9b64d482b9028dcd2;p=linux-beck.git

vmalloc: call flush_cache_vunmap() from unmap_kernel_range()

Impact: proper vcache flush on unmap_kernel_range()

flush_cache_vunmap() should be called before pages are unmapped.  Add
a call to it in unmap_kernel_range().
