This generates a circular dependency. To avoid that, asm/processor.h shall not be included in mmu-hash.h In order to do that, this patch moves into a new header called asm/task_size_user64.h the information from asm/processor.h required by mmu-hash.h Signed-off-by: Christophe Leroy Reviewed-by: Nicholas Piggin --- arch/powerpc/include/asm/book3s/64/mmu-hash.h | 2 +- arch/powerpc/include/asm/processor.h | 34 +--------------------- arch/powerpc/include/asm/task_size_user64.h | 42 +++++++++++++++++++++++++++ arch/powerpc/kvm/book3s_hv_hmi.c | 1 + 4 files changed, 45 insertions(+), 34 deletions(-) create mode 100644 arch/powerpc/include/asm/task_size_user64.h diff --git a/arch/powerpc/include/asm/book3s/64/mmu-hash.h b/arch/powerpc/include/asm/book3s/64/mmu-hash.h index 12e522807f9f..b2aba048301e 100644 --- a/arch/powerpc/include/asm/book3s/64/mmu-hash.h +++ b/arch/powerpc/include/asm/book3s/64/mmu-hash.h @@ -23,7 +23,7 @@ */ #include #include -#include +#include #include /* diff --git a/arch/powerpc/include/asm/processor.h b/arch/powerpc/include/asm/processor.h index ee58526cb6c2..692f7383d461 100644 --- a/arch/powerpc/include/asm/processor.h +++ b/arch/powerpc/include/asm/processor.h @@ -95,40 +95,8 @@ void release_thread(struct task_struct *); #endif #ifdef CONFIG_PPC64 -/* - * 64-bit user address space can have multiple limits - * For now supported values are: - */ -#define TASK_SIZE_64TB (0x0000400000000000UL) -#define TASK_SIZE_128TB (0x0000800000000000UL) -#define TASK_SIZE_512TB (0x0002000000000000UL) -#define TASK_SIZE_1PB (0x0004000000000000UL) -#define TASK_SIZE_2PB (0x0008000000000000UL) -/* - * With 52 bits in the address we can support - * upto 4PB of range. - */ -#define TASK_SIZE_4PB (0x0010000000000000UL) -/* - * For now 512TB is only supported with book3s and 64K linux page size. - */ -#if defined(CONFIG_PPC_BOOK3S_64) && defined(CONFIG_PPC_64K_PAGES) -/* - * Max value currently used: - */ -#define TASK_SIZE_USER64 TASK_SIZE_4PB -#define DEFAULT_MAP_WINDOW_USER64 TASK_SIZE_128TB -#define TASK_CONTEXT_SIZE TASK_SIZE_512TB -#else -#define TASK_SIZE_USER64 TASK_SIZE_64TB -#define DEFAULT_MAP_WINDOW_USER64 TASK_SIZE_64TB -/* - * We don't need to allocate extended context ids for 4K page size, because - * we limit the max effective address on this config to 64TB. - */ -#define TASK_CONTEXT_SIZE TASK_SIZE_64TB -#endif +#include /* * 32-bit user address space is 4GB - 1 page diff --git a/arch/powerpc/include/asm/task_size_user64.h b/arch/powerpc/include/asm/task_size_user64.h new file mode 100644 index 000000000000..a4043075864b --- /dev/null +++ b/arch/powerpc/include/asm/task_size_user64.h @@ -0,0 +1,42 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef _ASM_POWERPC_TASK_SIZE_USER64_H +#define _ASM_POWERPC_TASK_SIZE_USER64_H + +#ifdef CONFIG_PPC64 +/* + * 64-bit user address space can have multiple limits + * For now supported values are: + */ +#define TASK_SIZE_64TB (0x0000400000000000UL) +#define TASK_SIZE_128TB (0x0000800000000000UL) +#define TASK_SIZE_512TB (0x0002000000000000UL) +#define TASK_SIZE_1PB (0x0004000000000000UL) +#define TASK_SIZE_2PB (0x0008000000000000UL) +/* + * With 52 bits in the address we can support + * upto 4PB of range. + */ +#define TASK_SIZE_4PB (0x0010000000000000UL) + +/* + * For now 512TB is only supported with book3s and 64K linux page size. + */ +#if defined(CONFIG_PPC_BOOK3S_64) && defined(CONFIG_PPC_64K_PAGES) +/* + * Max value currently used: + */ +#define TASK_SIZE_USER64 TASK_SIZE_4PB +#define DEFAULT_MAP_WINDOW_USER64 TASK_SIZE_128TB +#define TASK_CONTEXT_SIZE TASK_SIZE_512TB +#else +#define TASK_SIZE_USER64 TASK_SIZE_64TB +#define DEFAULT_MAP_WINDOW_USER64 TASK_SIZE_64TB +/* + * We don't need to allocate extended context ids for 4K page size, because + * we limit the max effective address on this config to 64TB. + */ +#define TASK_CONTEXT_SIZE TASK_SIZE_64TB +#endif + +#endif /* CONFIG_PPC64 */ +#endif /* _ASM_POWERPC_TASK_SIZE_USER64_H */ diff --git a/arch/powerpc/kvm/book3s_hv_hmi.c b/arch/powerpc/kvm/book3s_hv_hmi.c index e3f738eb1cac..64b5011475c7 100644 --- a/arch/powerpc/kvm/book3s_hv_hmi.c +++ b/arch/powerpc/kvm/book3s_hv_hmi.c @@ -24,6 +24,7 @@ #include #include #include +#include void wait_for_subcore_guest_exit(void) { -- 2.13.3
