From db0e7d4e42b0557caad5112b405da59c933bea24 Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Tue, 19 Feb 2019 16:57:15 +0100 Subject: MIPS: SGI-IP27: get rid of volatile and hubreg_t Replace hub register access with __raw_readq/__raw_writeq and get rid of hubreg_t completely. Also remove no longer (probably never used) used defines Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org --- arch/mips/sgi-ip27/ip27-hubio.c | 4 ++-- arch/mips/sgi-ip27/ip27-init.c | 2 +- arch/mips/sgi-ip27/ip27-irq.c | 4 ++-- arch/mips/sgi-ip27/ip27-memory.c | 6 +++--- arch/mips/sgi-ip27/ip27-nmi.c | 2 +- 5 files changed, 9 insertions(+), 9 deletions(-) (limited to 'arch/mips/sgi-ip27') diff --git a/arch/mips/sgi-ip27/ip27-hubio.c b/arch/mips/sgi-ip27/ip27-hubio.c index 2abe016a0ffc..68fb0cb89d9d 100644 --- a/arch/mips/sgi-ip27/ip27-hubio.c +++ b/arch/mips/sgi-ip27/ip27-hubio.c @@ -63,7 +63,7 @@ unsigned long hub_pio_map(cnodeid_t cnode, xwidgetnum_t widget, * after we write it. */ IIO_ITTE_PUT(nasid, i, HUB_PIO_MAP_TO_MEM, widget, xtalk_addr); - (void) HUB_L(IIO_ITTE_GET(nasid, i)); + __raw_readq(IIO_ITTE_GET(nasid, i)); return NODE_BWIN_BASE(nasid, widget) + (xtalk_addr % BWIN_SIZE); } @@ -135,7 +135,7 @@ static void hub_setup_prb(nasid_t nasid, int prbnum, int credits) **/ static void hub_set_piomode(nasid_t nasid) { - hubreg_t ii_iowa; + u64 ii_iowa; hubii_wcr_t ii_wcr; unsigned i; diff --git a/arch/mips/sgi-ip27/ip27-init.c b/arch/mips/sgi-ip27/ip27-init.c index e501c43c02db..83399e578b61 100644 --- a/arch/mips/sgi-ip27/ip27-init.c +++ b/arch/mips/sgi-ip27/ip27-init.c @@ -177,7 +177,7 @@ extern void ip27_reboot_setup(void); void __init plat_mem_setup(void) { - hubreg_t p, e, n_mode; + u64 p, e, n_mode; nasid_t nid; ip27_reboot_setup(); diff --git a/arch/mips/sgi-ip27/ip27-irq.c b/arch/mips/sgi-ip27/ip27-irq.c index 0dde6164a06f..f37155ef7ed9 100644 --- a/arch/mips/sgi-ip27/ip27-irq.c +++ b/arch/mips/sgi-ip27/ip27-irq.c @@ -85,7 +85,7 @@ static int ms1bit(unsigned long x) static void ip27_do_irq_mask0(void) { int irq, swlevel; - hubreg_t pend0, mask0; + u64 pend0, mask0; cpuid_t cpu = smp_processor_id(); int pi_int_mask0 = (cputoslice(cpu) == 0) ?
