2a9d0f04ba loader/i386/linux: Use central copy of grub_efi_find_mmap_size() 
Delete local copy of function to determine required buffer size for the
UEFI memory map, use helper in kern/efi/mm.c.

8db0a305e4 i386/linux: Add support for ext_lfb_base 
The EFI Graphics Output Protocol can return a 64-bit
linear frame buffer address in some firmware/BIOS
implementations. We currently only store the lower
32-bits in the lfb_base. This will eventually be
passed to Linux kernel and the efifb driver will
incorrectly interpret the framebuffer address as
32-bit address.

The Linux kernel has already added support to handle
64-bit linear framebuffer address in the efifb driver
since quite some time now.

This patch adds the support for 64-bit linear frame
buffer address in GRUB to address the above mentioned
scenario.

4bd4a88725 i386, x86_64, ppc: fix switch fallthrough cases with GCC7 
In util/getroot and efidisk slightly modify exitsing comment to mostly
retain it but still make GCC7 compliant with respect to fall through
annotation.

In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as
upstream.

In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to
suppress GCC7 warning.

In grub-core/gnulib/regexec.c use new __attribute__, because existing
annotation is not recognized by GCC7 parser (which requires that comment
immediately precedes case statement).

Otherwise add FALLTHROUGH comment.

it's preferable to avoid using so many PCRs. Instead, measure into PCRs 8

9a67e1ac8e Use full initializer for initrd_ctx to avoid fatal warnings with older GCC 
struct ... foo = { 0, } is valid initializer, but older GCC emits
warning which is fatal error due to -Werror=missing-field-initializer.
So simply use full initializer to avoid these errors. This was fixed
probably in GCC 4.7.

631a820038 Initialized initrd_ctx so we don't free a random pointer from the stack. 
Currently, if "linux" fails, the "goto fail;" in grub_cmd_initrd sends us
into grub_initrd_close() without grub_initrd_init() being called, and thus
it never clears initrd_ctx->components.  grub_initrd_close() then frees that
address, which is stale data from the stack.  If the stack happens to have a
stale *address* there that matches a recent allocation, then you'll get a
double free later.

So initialize the memory up front.
