X-Git-Tag: v3.15-rc1~81^2~13 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=75efba81513133fdd2f9c1ac9213bf86cc622f62;p=pandora-kernel.git CNS3xxx: Fix a WARN() related to IRQ allocation. WARNING: at drivers/irqchip/irq-gic.c:952 gic_init_bases+0xe4/0x2b8() Cannot allocate irq_descs @ IRQ16, assuming pre-allocated Backtrace: gic_init_bases from cns3xxx_init_irq+0x24/0x34 cns3xxx_init_irq from init_IRQ+0x24/0x2c init_IRQ from start_kernel+0x1a8/0x338 start_kernel from 0x2000806c The problem is that 64 CNS3xxx CPU interrupts, starting at 32, are allocated by the ARM platform-independent code (as requested by machine_desc->nr_irqs = 96), and then the GIC code tries to allocate them again. Tested on Gateworks Laguna board, masqueraded as CNS3420VB. Signed-off-by: Krzysztof Hałasa Signed-off-by: Arnd Bergmann --- Reading git-diff-tree failed
