tipc: allocate user memory with GFP_KERNEL flag
[ Upstream commit 57d5f64d83ab5b5a5118b1597386dd76eaf4340d ]
Until now, we allocate memory always with GFP_ATOMIC flag.
When the system is under memory pressure and a user tries to send,
the send fails due to low memory. However, the user application
can wait for free memory if we allocate it using GFP_KERNEL flag.
In this commit, we use allocate memory with GFP_KERNEL for all user
allocation.
