[PATCH] x86-64: Fix incorrect FP signals
This is the same patch that went into i386 just before 2.6.13 came out. I still can't build 64-bit user apps, so I tested with program (see below) in 32-bit mode on 64-bit kernel: Before: $ fpsig handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10 handler: altstack is at 0x0804b000, ebp = 0x0804bc7c handler: si_signo = 8, si_errno = 0, si_code = 0 [unknown] handler: fpu cwd = 0xb40, fpu swd = 0xbaa0 handler: i387 unmasked precision exception, rounded up After: $ fpsig handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10 handler: altstack is at 0x0804b000, ebp = 0x0804bc7c handler: si_signo = 8, si_errno = 0, si_code = 6 [inexact result] handler: fpu cwd = 0xb40, fpu swd = 0xbaa0 handler: i387 unmasked precision exception, rounded up Signed-off-by: Chuck Ebbert <76306.1226@compuserve.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
