Message-Id: <4abb3611309bf7b31520d990f426e5941b562b67.1632558672.git.christophe.leroy@csgroup.eu> Date: Sat, 25 Sep 2021 10:31:43 +0200 From: Christophe Leroy <christophe.leroy@...roup.eu> To: Benjamin Herrenschmidt <benh@...nel.crashing.org>, Paul Mackerras <paulus@...ba.org>, Michael Ellerman <mpe@...erman.id.au> Cc: Christophe Leroy <christophe.leroy@...roup.eu>, linux-kernel@...r.kernel.org, linuxppc-dev@...ts.ozlabs.org, Michael Neuling <mikey@...ling.org> Subject: [PATCH v2 2/3] powerpc: Stop using init_mem_is_free Generic parts of the kernel for instance core_kernel_text() use 'system_state' to check whether init memory has been freed. Do the same and stop using init_mem_is_free. Cc: Michael Neuling <mikey@...ling.org> Signed-off-by: Christophe Leroy <christophe.leroy@...roup.eu> --- arch_is_kernel_initmem_freed() is likely going to go away via the mm tree, in that case this patch will void. v2: Also remove declaration of init_mem_is_free.
