Subject: [PATCH 0/8] x86 signal code cleanups
Date: Mon, 6 Jun 2022 16:37:54 -0400 [thread overview]
Message-ID: <20220606203802.158958-1-brgerst@gmail.com> (raw)
The 32-bit signal code has significant differences from 64-bit, and
those are duplicated for native and compat modes. This patch series
merges the 32-bit code into one file, and does some general cleanups
in the x86 signal code. There should be no functional changes.
Brian Gerst (8):
x86/signal: Remove sig parameter from frame setup functions
x86/signal: Remove sigset_t parameter from frame setup functions
signal/compat: Remove compat_sigset_t override
x86: Remove __USER32_DS
x86/signal: Merge get_sigframe()
x86/signal: Add ABI prefixes to frame setup functions
x86/signal/32: Merge native and compat 32-bit signal code
x86/signal/64: Move 64-bit signal code to its own file
