Bootloader fork rebase:
- Base changed from 0.1.0 pre-patched archive to upstream 1.0.0 tag (c7eeb9f)
- Applied 0001-redbear-local-forks.patch (Cargo.toml crate path redirects)
- Applied fix-uefi-alloc-panic.patch equivalents (4 panic!() -> graceful
error handling in src/main.rs)
- Applied P5-live-preload-cap-1gib.patch (1 GiB cap on live image preload)
- Skipped: P0 GPT partition scan (requires new module + integration),
P1 timeout/default-resolution, P2 live preload guard (subsumed by
panic fixes + cap), P3 live image safe read, P4 large ISO boot,
redox.patch — to be applied in dedicated rebase session.
firmware-loader/Cargo.toml: version 0.1.0 -> 0.3.0 (sync with other
Red Bear custom crates which are at 0.3.0).
fork-upstream-map.toml: bootloader back from PENDING_REBASE to 1.0.0
since the partial rebase matches upstream 1.0.0 content.
fork-upstream-map.toml: base restored to 'main' tracked (was correctly
tracked by build-redbear.sh).

dnl In the next release of POSIX, free must preserve errno.

dnl So far, we know of three platforms that do this:
|
|
dnl * glibc >= 2.33, thanks to the fix for this bug:
|
|
dnl <https://sourceware.org/bugzilla/show_bug.cgi?id=17924>
|
|
dnl * OpenBSD >= 4.5, thanks to this commit:
|
|
dnl <https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libc/stdlib/malloc.c.diff?r1=1.100&r2=1.101&f=h>
|
|
dnl * Solaris, because its malloc() implementation is based on brk(),
|
|
dnl not mmap(); hence its free() implementation makes no system calls.
|
|
dnl For other platforms, you can only be sure if they state it in their
|
|
dnl documentation, or by code inspection of the free() implementation in libc.
