Nishanth Aravamudan af442a1baa powerpc: Ensure dtl buffers do not cross 4k boundary ... Future releases of fimrware will enforce a requirement that DTL buffers do not cross a 4k boundary. Commit 127493d5dc satisfies this requirement for CONFIG_VIRT_CPU_ACCOUNTING=y kernels, but if !CONFIG_VIRT_CPU_ACCOUNTING && CONFIG_DTL=y, the current code will fail at dtl registration time. Fix this by making the kmem cache from 127493d5dc visible outside of setup.c and using the same cache in both dtl.c and setup.c. This requires a bit of reorganization to ensure ordering of the kmem cache and buffer allocations. Note: Since firmware now limits the size of the buffer, I made dtl_buf_entries read-only in debugfs. Tested with upcoming firmware with the 4 combinations of CONFIG_VIRT_CPU_ACCOUNTING and CONFIG_DTL.
