The patch titled
Subject: ptrace: in PEEK_SIGINFO, check syscall bitness, not task bitness
has been removed from the -mm tree. Its filename was
ptrace-in-peek_siginfo-check-syscall-bitness-not-task-bitness.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: ptrace: in PEEK_SIGINFO, check syscall bitness, not task bitness
Users of the 32-bit ptrace() ABI expect the full 32-bit ABI. siginfo
translation should check ptrace() ABI, not caller task ABI.
This is an ABI change on SPARC. Let's hope that no one relied on the old
buggy ABI.
