Michael Chang 15aee573d2 xen_file: Fix invalid payload size 2016-03-11 10:26:51 +01:00
Vladimir Serbinenko 2ebef43cf6 bsd: Ensure that kernel is loaded before loading module. 
kernel_type may be set to the type of failed kernel. This patching-up is
easier than to reflow kernel loading routines.

Andrei Borzenkov 15dfea842c multiboot2: zero reserved field in memory map 
Documentation says, bootloader should set reserved field to zero.

Eric Snowberg 080a20861c OBP available region contains grub. Start at grub_phys_end. 
This prevents a problem where grub was being overwritten since
grub_phys_start does not start at a zero offset within the memory
map.

Bernhard Übelacker 61c778f640 loader/linux: Make trailer initrd entry aligned again. 
Regression from commit:
  loader/linux: do not pad initrd with zeroes at the end
  a8c473288d

Wimboot fails since the change above because it expects the "trailer"
initrd element on an aligned address.
This issue shows only when newc_name is used and the last initrd
entry has a not aligned size.

Vladimir Serbinenko c856be6bca multiboot1: never place modules in low memory. 
While in theory permitted by the spec, modules rarely fit in low memory
anyway and not every kernel is able to handle modules in low memory anyway.
At least VMWare is known not to be able to handle modules at arbitrary
locations.

Andrei Borzenkov a8c473288d loader/linux: do not pad initrd with zeroes at the end 
Syslinux memdisk is using initrd image and needs to know uncompressed
size in advance. For gzip uncompressed size is at the end of compressed
stream. Grub padded each input file to 4 bytes at the end, which means
syslinux got wrong size.

Linux initramfs loader apparently does not care about trailing alignment.
So change code to align beginning of each file instead which atomatically
gives us the correct size for single file.

Andrei Borzenkov 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.
