Subject: [PATCH RESEND 1/2] uapi/asm-generic: Allow defining a custom __SIGINFO struct
Date: Tue,  2 Jul 2019 17:52:01 -0700	[thread overview]
Message-ID: <20190703005202.7578-2-alistair.francis@wdc.com> (raw)
In-Reply-To: <20190703005202.7578-1-alistair.francis@wdc.com>

Allow defining a custom __SIGINFO struct. This allows architectures to
apply their own padding and allignment requirements to the struct. This
is similar to the __ARCH_SI_ATTRIBUTES #define that already exists, but
applies to the __SIGINFO struct instead of the siginfo_t struct.
