In preparation to enabling -Wvla, remove VLA and replace it with a fixed-length array instead.
Fixed as part of the directive to remove all VLAs from the kernel: https://lkml.org/lkml/2018/3/7/621 Also, remove max_interleave as it is no longer useful. Reviewed-by: Mauro Carvalho Chehab <[email protected]> Signed-off-by: Gustavo A. R. Silva <[email protected]> --- Changes in v4: - Remove max_interleave. Changes in v3: - Update macro MAX_INTERLEAVE in order to avoid too long lines. This change is based on Mauro's feedback. - Update changelog with Mauro's Reviewed-by. Changes in v2: - Use macro max_t to compute the max of all three array sizes. This change is based on Borislav's feedback. drivers/edac/sb_edac.c | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) diff --git a/drivers/edac/sb_edac.c b/drivers/edac/sb_edac.c index 8721002..4a89c80 100644 --- a/drivers/edac/sb_edac.c +++ b/drivers/edac/sb_edac.c @@ -110,6 +110,10 @@ static const u32 knl_interleave_list[] = { 0xdc, 0xe4, 0xec, 0xf4, 0xfc, /* 15-19 */ 0x104, 0x10c, 0x114, 0x11c, /* 20-23 */ }; +#define MAX_INTERLEAVE \ + (max_t(unsigned int, ARRAY_SIZE(sbridge_interleave_list), \ + max_t(unsigned int, ARRAY_SIZE(ibridge_interleave_list), \ + ARRAY_SIZE(knl_interleave_list)))) struct interleave_pkg { unsigned char start; @@ -321,7 +325,6 @@ struct sbridge_info { const u32 *interleave_list; const struct interleave_pkg *interleave_pkg; u8 max_sad; - u8 max_interleave; u8 (*get_node_id)(struct sbridge_pvt *pvt); enum mem_type (*get_memory_type)(struct sbridge_pvt *pvt); enum dev_type (*get_width)(struct sbridge_pvt *pvt, u32 mtr); @@ -1899,7 +1902,7 @@ static int get_memory_error_data(struct mem_ctl_info *mci, int n_rir, n_sads, n_tads, sad_way, sck_xch; int sad_interl, idx, base_ch; int interleave_mode, shiftup = 0; - unsigned sad_interleave[pvt->info.max_interleave]; + unsigned int sad_interleave[MAX_INTERLEAVE]; u32 reg, dram_rule; u8 ch_way, sck_way, pkg, sad_ha = 0; u32 tad_offset; @@ -3169,7 +3172,6 @@ static int sbridge_register_mci(struct sbridge_dev *sbridge_dev, enum type type) pvt->info.dram_attr = dram_attr; pvt->info.max_sad = ARRAY_SIZE(ibridge_dram_rule); pvt->info.interleave_list = ibridge_interleave_list; - pvt->info.max_interleave = ARRAY_SIZE(ibridge_interleave_list); pvt->info.interleave_pkg = ibridge_interleave_pkg; pvt->info.get_width = ibridge_get_width; @@ -3194,7 +3196,6 @@ static int sbridge_register_mci(struct sbridge_dev *sbridge_dev, enum type type) pvt->info.dram_attr = dram_attr; pvt->info.max_sad = ARRAY_SIZE(sbridge_dram_rule); pvt->info.interleave_list = sbridge_interleave_list; - pvt->info.max_interleave = ARRAY_SIZE(sbridge_interleave_list); pvt->info.interleave_pkg = sbridge_interleave_pkg; pvt->info.get_width = sbridge_get_width; @@ -3219,7 +3220,6 @@ static int sbridge_register_mci(struct sbridge_dev *sbridge_dev, enum type type) pvt->info.dram_attr = dram_attr; pvt->info.max_sad = ARRAY_SIZE(ibridge_dram_rule); pvt->info.interleave_list = ibridge_interleave_list; - pvt->info.max_interleave = ARRAY_SIZE(ibridge_interleave_list); pvt->info.interleave_pkg = ibridge_interleave_pkg; pvt->info.get_width = ibridge_get_width; @@ -3244,7 +3244,6 @@ static int sbridge_register_mci(struct sbridge_dev *sbridge_dev, enum type type) pvt->info.dram_attr = dram_attr; pvt->info.max_sad = ARRAY_SIZE(ibridge_dram_rule); pvt->info.interleave_list = ibridge_interleave_list; - pvt->info.max_interleave = ARRAY_SIZE(ibridge_interleave_list); pvt->info.interleave_pkg = ibridge_interleave_pkg; pvt->info.get_width = broadwell_get_width; @@ -3269,7 +3268,6 @@ static int sbridge_register_mci(struct sbridge_dev *sbridge_dev, enum type type) pvt->info.dram_attr = dram_attr_knl; pvt->info.max_sad = ARRAY_SIZE(knl_dram_rule); pvt->info.interleave_list = knl_interleave_list; - pvt->info.max_interleave = ARRAY_SIZE(knl_interleave_list); pvt->info.interleave_pkg = ibridge_interleave_pkg; pvt->info.get_width = knl_get_width; -- 2.7.4
