Subject: [PATCH] Revert "crypto: rsa-pkcs1pad - Replace GFP_ATOMIC with GFP_KERNEL in pkcs1pad_encrypt_sign_complete"
Git-commit: d52b0c780c1f8cdd0cef9c6e683ab568d04bb19d
Patch-mainline: v6.3-rc1
References: git-fixes
This reverts commit 1ca2809897155f1adc43e4859b4a3582e235c09a.
While the akcipher API as a whole is designed to be called only
from thread context, its completion path is still called from
softirq context as usual. Therefore we must not use GFP_KERNEL
on that path.
