  "message": "powerpc: Fix up the kdump base cap to 128M\n\nThe current logic sets the kdump base to min of 2G or ppc64_rma_size/2.\nOn PowerNV kernel the first memory block \u0027memory@0\u0027 can be very large,\nequal to the DIMM size with ppc64_rma_size value capped to 1G. Hence on\nPowerNV, kdump base is set to 512M resulting kdump to fail while allocating\npaca array. This is because, paca need its memory from RMA region capped\nat 256M (see allocate_pacas()).\n\nThis patch lowers the kdump base cap to 128M so that kdump kernel can\nsuccessfully get memory below 256M for paca allocation.\n\nSigned-off-by: Mahesh Salgaonkar \u003cmahesh@linux.vnet.ibm.com\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n",
