From df570b9c284701d08b22aa00cbfcf870b7f1b7c1 Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Sun, 27 Aug 2006 11:04:26 -0400 Subject: [PARISC] Switch is_compat_task to use TIF_32BIT Stop using PER_LINUX32 to designate processes needing compaterizing. Convert is_compat_task to use TIF_32BIT and set TIF_32BIT in binfmt_elf32.c Signed-off-by: Kyle McMartin --- arch/parisc/kernel/binfmt_elf32.c | 24 +----------------------- arch/parisc/kernel/signal.c | 5 ++--- 2 files changed, 3 insertions(+), 26 deletions(-) (limited to 'arch/parisc') diff --git a/arch/parisc/kernel/binfmt_elf32.c b/arch/parisc/kernel/binfmt_elf32.c index d1833f164bbe..1e64e7b88110 100644 --- a/arch/parisc/kernel/binfmt_elf32.c +++ b/arch/parisc/kernel/binfmt_elf32.c @@ -87,7 +87,7 @@ struct elf_prpsinfo32 */ #define SET_PERSONALITY(ex, ibcs2) \ - current->personality = PER_LINUX32; \ + set_thread_flag(TIF_32BIT); \ current->thread.map_base = DEFAULT_MAP_BASE32; \ current->thread.task_size = DEFAULT_TASK_SIZE32 \ @@ -102,25 +102,3 @@ cputime_to_compat_timeval(const cputime_t cputime, struct compat_timeval *value) } #include "../../../fs/binfmt_elf.c" - -/* Set up a separate execution domain for ELF32 binaries running - * on an ELF64 kernel */ - -static struct exec_domain parisc32_exec_domain = { - .name = "Linux/ELF32", - .pers_low = PER_LINUX32, - .pers_high = PER_LINUX32, -}; - -static int __init parisc32_exec_init(void) -{ - /* steal the identity signal mappings from the default domain */ - parisc32_exec_domain.signal_map = default_exec_domain.signal_map; - parisc32_exec_domain.signal_invmap = default_exec_domain.signal_invmap; - - register_exec_domain(&parisc32_exec_domain); - - return 0; -} - -__initcall(parisc32_exec_init); diff --git a/arch/parisc/kernel/signal.c b/arch/parisc/kernel/signal.c index bb83880c5ee3..ee6653edeb7a 100644 --- a/arch/parisc/kernel/signal.c +++ b/arch/parisc/kernel/signal.c @@ -26,7 +26,6 @@ #include #include #include -#include #include #include #include @@ -433,13 +432,13 @@ setup_rt_frame(int sig, struct k_sigaction *ka, siginfo_t *info, if (in_syscall) { regs->gr[31] = haddr; #ifdef __LP64__ - if (personality(current->personality) == PER_LINUX) + if (!test_thread_flag(TIF_32BIT)) sigframe_size |= 1; #endif } else { unsigned long psw = USER_PSW; #ifdef __LP64__ - if (personality(current->personality) == PER_LINUX) + if (!test_thread_flag(TIF_32BIT)) psw |= PSW_W; #endif -- cgit v1.2.1
