Mark Brown 41609ff430 [ARM] 5449/1: S3C: Use disable_irq_nosync() to fix boot lockups ... With 2.6.30-rc1 on SMDK6410 I experience a soft lockup on bootup when the Samsung serial driver attempts to disable the transmit interrupt from within the transmit interrupt handler: it calls disable_irq() which locks up due to attempting to synchronise with the running handler. Fix this by using disable_irq_nosync(). Also make the same change in the recieve path. Backtrace: [<c002a914>] (__irq_svc+0x34/0x80) from [<c00696c0>] (synchr) [<c00696c0>] (synchronize_irq+0xc/0xcc) from [<c018d434>] (s) [<c018d434>] (s3c24xx_serial_stop_tx+0x1c/0x3c) from [<c018d) [<c018d54c>] (s3c24xx_serial_tx_chars+0xf8/0x104) from [<c00) [<c0068bcc>] (handle_IRQ_event+0x74/0x118) from [<c006ab04>]) [<c006ab04>] (handle_level_irq+0x100/0x118) from [<c00349c4>) [<c00349c4>] (s3c_irq_demux_uart+0x94/0xc4) from [<c002a050>) [<c002a050>] (_text+0x50/0x6c) from [<c002a914>] (__irq_svc+) Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>		2009-04-15 10:01:02 +01:00
