-Subject: [PATCH 8/8] crypto: crypto4xx - put temporary dst sg into request ctx
-
-This patch fixes a crash that happens when testing rfc4543(gcm(aes))
-
-Unable to handle kernel paging request for data at address 0xf59b3420
-Faulting instruction address: 0xc0012994
-Oops: Kernel access of bad area, sig: 11 [#1]
-BE PowerPC 44x Platform
-Modules linked in: tcrypt(+) crypto4xx [...]
-CPU: 0 PID: 0 Comm: swapper Tainted: G O 4.17.0-rc1+ #23
-NIP: c0012994 LR: d3077934 CTR: 06026d49
-REGS: cfff7e30 TRAP: 0300 Tainted: G O (4.17.0-rc1+)
-MSR: 00029000 <CE,EE,ME> CR: 44744822 XER: 00000000

-NIP [c0012994] __dma_sync+0x58/0x10c
-LR [d3077934] crypto4xx_bh_tasklet_cb+0x188/0x3c8 [crypto4xx]
-
-__dma_sync was fed the temporary _dst that crypto4xx_build_pd()
-had in it's function stack. This clearly never worked.
-This patch therefore overhauls the code from the original driver
-and puts the temporary dst sg list into aead's request context.
