From bf8fde785b872282e7e86d9ea8a9c4e543985bb3 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Mon, 4 Feb 2008 22:31:04 -0800 Subject: uml: miscellaneous code cleanups Code tidying - the pid field of struct irq_fd isn't used, so it is removed os_set_fd_async needed to read flags before changing them, it doesn't need a pid passed in because it can call getpid itself, and a block of unused code needed deleting os_get_exec_close was unused, so it is removed ptrace_child called _exit for historical reasons which are no longer valid, so just calls exit instead Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/um/kernel/smp.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'arch/um/kernel/smp.c') diff --git a/arch/um/kernel/smp.c b/arch/um/kernel/smp.c index a12e5bd15790..869ac6802209 100644 --- a/arch/um/kernel/smp.c +++ b/arch/um/kernel/smp.c @@ -74,8 +74,7 @@ static int idle_proc(void *cpup) if (err < 0) panic("CPU#%d failed to create IPI pipe, err = %d", cpu, -err); - os_set_fd_async(cpu_data[cpu].ipi_pipe[0], - current->thread.mode.tt.extern_pid); + os_set_fd_async(cpu_data[cpu].ipi_pipe[0]); wmb(); if (cpu_test_and_set(cpu, cpu_callin_map)) { @@ -128,8 +127,7 @@ void smp_prepare_cpus(unsigned int maxcpus) if (err < 0) panic("CPU#0 failed to create IPI pipe, errno = %d", -err); - os_set_fd_async(cpu_data[me].ipi_pipe[0], - current->thread.mode.tt.extern_pid); + os_set_fd_async(cpu_data[me].ipi_pipe[0]); for (cpu = 1; cpu < ncpus; cpu++) { printk(KERN_INFO "Booting processor %d...\n", cpu); -- cgit v1.2.3
