[PATCH 2/2] Adding enable_kernel_vsx() to access VSX instructions

vmx-crypto driver make use of some VSX instructions which are only available if VSX is enabled. Running in cases where VSX are not enabled vmx-crypto fails in a VSX exception. In order to fix this enable_kernel_vsx() was added to turn on VSX instructions for vmx-crypto. Signed-off-by: Leonidas S

Re: crypto: nx - Fix reentrancy bugs

PS it would appear that you can make this completely reentrant by moving all the data from the tfm into the reqeust. Could you work on this and remove the spinlock completely? Yes. Thank you! -- To unsubscribe from this list: send the line unsubscribe linux-crypto in the body of a message

Re: linux-next: Tree for Mar 11 (powerpc build failure due to vmx crypto code)

A little bit later, but thank you guys for fix it. The issue seems happens just in BE machines, and using _GLOBAL instead .globl seems fix it so build the correct vmx-crypto.ko. On LE it does not happens. On Thu, Mar 12, 2015 at 02:53:27PM +1100, Herbert Xu wrote: On Wed, Mar 11, 2015 at
