Commit 5bc41db756 ("net/dhcp: Add explicit net_dhcp command")
introduced the new command "net_dhcp", which (for now) is an alias for
the existing "net_bootp". Unfortunately the TEXI documentation was not
adjusted accordingly.
Rename the existing paragraph about net_bootp to read net_dhcp instead,
and make the net_bootp stanza point to this new command.
On the way add the newly parsed TFTP_SERVER_NAME and BOOTFILE_NAME
packets to the list of supported DHCP options.

Currently, gpt_offset is uninitialised when using a BIOS Boot Partition
but is used unconditionally inside save_blocklists. Instead, ensure it
is always initialised to 0 (note that there is already separate code to
do the equivalent adjustment after we call save_blocklists on this code
path).
This patch has been tested on a T5-2 LDOM.

MinGW for i386-pc without this option generates a .rdata$zzz symbol that is
page-aligned and hence lzma_decompress no longer fits in its allocated space.
Additionally, MinGW with -fno-ident also saves a bit of space in modules. In
case of other compilers we already strip the relevant sections, so, this
option has no effect.

we still still have the 'auto' default to fall back to. Allow getting to this
fallback by not trying to parse 'text' as a modespec.
This is because 'text' correctly doesn't parse as a modespec, and ought to have
been ignored before we got to that point, just like it is immediately picked if
we're running on a system where 'text' is a supported video mode.

The function grub_get_node_path() could return uninitialized offset with

2 * indirect_blks + dindirect_blks. The uninitialized offset is then used
by function grub_f2fs_get_block() because level == 0 is valid and
meaningful return to be processed.
The fix is to set level = -1 as return value by grub_get_node_path() to
signify an error that the input block cannot be handled. Any caller
should therefore check level is negative or not before processing the

This misbehavior was unmasked by commit a51f953f4e ("mkimage: Align

because everything became page aligned.
To put things into proper order, let's move the arm trampolines into the

Current comments forms are annoying, so, some of them are disallowed
starting from now. New rules are more flexible and mostly aligned
with, e.g., Linux kernel comments rules.

Previously the setup_header length was just assumed to be the size of the
linux_kernel_params struct. The linux x86 32-bit boot protocol says that the
end of the linux_i386_kernel_header is at 0x202 + the byte value at 0x201 in
the linux_i386_kernel_header. So, calculate the size of the header using the
end of the linux_i386_kernel_header, rather than assume it is the size of the
linux_kernel_params struct.
Additionally, add some required members to the linux_kernel_params
struct and align the content of linux_i386_kernel_header struct with
it. New members naming was taken directly from Linux kernel source.
linux_kernel_params and linux_i386_kernel_header structs require more
cleanup. However, this is not urgent, so, let's do this after release.
Just in case...

Recent versions of binutils dropped support for the a.out and COFF
formats on sparc64 targets. Since the boot loader on sparc64 is
supposed to be an a.out binary and the a.out header entries are
rather simple to calculate in our case, we just write the header
ourselves instead of relying on external tools to do that.
