Subject: eal/linux: use libc malloc in interrupt handling
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4bb69970afd7dd819d5c70f423bac48efe81739c;p=dpdk.git

eal/linux: use libc malloc in interrupt handling

IPC uses interrupts API internally, and memory subsystem uses IPC.
Therefore, IPC should not use rte_malloc to avoid circular dependency.
Switch to using regular glibc malloc in interrupts API.
