kernel_fpu fixes
This patch fixes a few issues when detecting which kernel_fpu functions are available. - Use kernel_fpu_begin() if it's exported on newer kernels. - Use ZFS_LINUX_TRY_COMPILE_SYMBOL() to choose the right kernel_fpu function when using --enable-linux-builtin. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Tony Hutter <[email protected]> Closes #8259 Closes #8363
