* [PATCH] Add additional argument to bootmem reservation
@ 2007-10-19 15:07 Bernhard Walle
0 siblings, 0 replies; only message in thread
From: Bernhard Walle @ 2007-10-19 15:07 UTC (permalink / raw)
To: akpm; +Cc: linux-kernel, linux-arch
This patch adds the additional bootmem reservation argument to all other
architectures which didn't compile after
kexec-introduce-bootmem_exclusive.patch has been merged [1].
It also adds a flags argument to reserve_bootmem_node().
I tested compilation on i386, x86_64 and ia64 with different memory
configurations. I hope that all other architectures work again, if not, drop me
a note with the compiler error and I'll create a patch that fixes it.
[1] Andrew, I thought it was clear from my patch description that the patch
was not ready to be merged -- however, that patch is the fix that was
missing, so no need to drop it now.
