Ashish Kalra c50ec15725 ACPI: APEI: Fix integer overflow in ghes_estatus_pool_init()
[ Upstream commit 43d2748394 ]

Change num_ghes from int to unsigned int, preventing an overflow
and causing subsequent vmalloc() to fail.

The overflow happens in ghes_estatus_pool_init() when calculating
len during execution of the statement below as both multiplication
operands here are signed int:

len += (num_ghes * GHES_ESOURCE_PREALLOC_MAX_SIZE);

The following call trace is observed because of this bug:

[    9.317108] swapper/0: vmalloc error: size 18446744071562596352, exceeds total pages, mode:0xcc0(GFP_KERNEL), nodemask=(null),cpuset=/,mems_allowed=0-1
