From: Raphael S. Carvalho <raphael.scarv at gmail.com> v2: Extract ADV_SIZE automatically from libinstaller/setadv.h. Calc the size of ldlinux.sys from ldlinux.bin, and check if it exceeds the limit. ldlinux.sys must fit between the bootsector and two copies of ADV whose size may vary. Thus, the size of ldlinux.sys can be at most: 65...

From: Raphael S. Carvalho <raphael.scarv at gmail.com> My commit 09f4ac33 broke 'com32/lib/syslinux/disk.c' __lowmem doesn't work for declarations outside the core. Using __lowmem outside the core wouldn't have the desired effect, then lmalloc must be used instead to store dapa into the correct section (".lowmem&...

...ldlinux.sys (limit) can be at most: 65536 - 2 * ADV_SIZE - 512. Certain file systems (such as BTRFS and UFS2) will rely on ldlinux.sys being installed on the 0-64k range, thus it can't exceed the limit, otherwise the superblock would be corrupted.

From: Raphael S. Carvalho <raphael.scarv at gmail.com> This patch finishes the MultiFS support. init_multifs gets called in the main (startup) function of ldlinux.c32, so MultiFS will be initialized automatically. init_multifs calls enable_multifs (lives in the core) to hook get_fs_info.

From: Raphael S. Carvalho <raphael.scarv at gmail.com> Most of file system drivers initialize the cache themselves. The problem is that the same cache could be again initialized later, then invalidating the previous one. This patch fixes this. Problem found while auditing the code. Signed-off-by: Raphael S.
