For sys/boot/i386 and sys/boot/pc98, separate flags to be passed directly to the linker (LD_FLAGS) from flags passed indirectly, via the compiler driver (LDFLAGS). This is because several Makefiles under sys/boot/i386 and sys/boot/pc98 use ${LD} directly to link, and the normal LDFLAGS value should not be used in these cases.

When rebooting (exiting) from the BTX loader, make sure to restore the GDT from the correct segment, otherwise a triple fault would be caused. In some virtual environments (VMware, VirtualBox, etc) this could lead to a unhandled error or hang in the guest emulation software. Thanks to avg and jhb for a few hints in the right direction. Noticed by: Jeremy Chadwick (and many others)

Declare some variables static in order to reduce the object size and redo r232822 (MFC'ed to stable/7 in r232966) in a less hackish way.

Fix a bug introduced in r223938 (MFC'ed to stable/7 in r224410); on big-endian machines coping a 32-bit quantum bytewise to the address of a 64-bit variable results in writing to the "wrong" 32-bit half so adjust the address accordingly. This fix is implemented in a hackish way for two reasons: o in order to be able to get it into 8.3 with zero impact on the little- endian architectures where this bug has no effect and o to avoid blowing the x86 boot2 out of the water again when compiling it with clang, which all sane versions of this fix tested do. This change fixes booting from UFS1 file systems on big-endian machines.

Fix a long standing bug. The caller expects a non-zero value for success. Luckily keyboard probing was turned off by default from the first revision.

Add kern.cam.boot_delay description (with reasonable default) to default/loader.conf This should help people installing ${OS} to USB devices, where there are frequently cases where kernel tries to mount root before actual umass sensing is finished. Reviewed by: mav Approved by: kib

- Mark getc() as inline, this has no effect on gcc but helps clang. - Move getc() body before xgetc() so gcc does not emit a warning about function having no body. Approved by: jhb

Some more shrinking. o bunch of variables are turned into uint8_t o initial setting of namep[] in lookup() is removed as it's only overwritten a few lines down o kname is explicitly initialized in main() as BSS in boot2 is not zeroed o the setting and reading of "fmt" in load() is removed o buf in printf() is made static to save space Reviewed by: jhb Tested by: me and Fabian Keil
