Subject: [PATCH v2 0/3] x86: "brk" allocator
Date: Mon, 27 Jul 2026 12:18:11 +0200 [thread overview]
Message-ID: <31ba7ff2-a42d-44aa-976c-17fbff44a56f@suse.com> (raw)
Derive for our purposes something similar to what Linux has been having for
a long while.
v2 is merely a re-base, mainly targeted at reminding people that this series
is still pending review.
1: x86: introduce "brk" allocator
2: x86/EFI: replace ebmalloc()
3: xhci-dbc: use brk_alloc()
To reduce padding holes, .bss.page_aligned and per-CPU data may want moving
immediately ahead of __brk_start[]. Albeit then the tail of per-CPU data will
all be padding space; sadly the TSS wants/needs page-aligning for XPTI
purposes.
