[Qemu-trivial] [PATCH v2] Fix ABI incompatibility between Qemu-aarch64 and Linux Kernel in signal handling.

[Maxim Ostapenko <m.ostapenko@partner.samsung.com>]

Thanks again,

I've updated the patch. Is this correct now?

Subject: [PATCH] linux-user: wrong TARGET_SI_PAD_SIZE value for some 
targets.

Fix TARGET_SI_PAD_SIZE calculation to match the way the kernel does it.
Use different TARGET_SI_PREAMBLE_SIZE for 32-bit and 64-bit targets.
