linux: fix bit tests

2014-01-05T13:22:15Z

The pattern is !x&y. An expression of this form is almost always meaningless, because it combines a boolean operator with a bit operator. In particular, if the rightmost bit of y is 0, the result will always be 0. Fixed using coccinelle. // !x&y combines boolean negation with bitwise and // // Confidence: High // Copyright: (C) Gilles Muller, Julia Lawall, EMN, DIKU. GPLv2. // URL: http://www.emn.fr/x-info/coccinelle/rules/notand.html // Options: @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) * linux/src/drivers/scsi/FlashPoint.c: Fix bit tests.

Fix slow boot in virtualbox

2012-12-27T20:48:42Z

By disabling some of the most slow drivers by default, and giving progress feedback to the user. * linux/configfrag.ac (CONFIG_SCSI_NCR53C7xx, CONFIG_SCSI_AIC7XXX, CONFIG_SCSI_GDTH): Disable by default * linux/src/drivers/scsi/eata.c (__initfunc): Don't feed line in probe message. * linux/src/drivers/scsi/hosts.c (scsi_init): Print SCSI probe progress.

Fix compilation error with older versions of GCC

2012-11-19T15:28:16Z

Some versions of GCC will error if you define a type twice (even if the definition is the same). The NCR53C8XX SCSI driver defines 'vm_offset_t', this is also defined in vm_types.h and will therefore cause a compilation error depending on the GCC version. * linux/src/drivers/scsi/ncr53c8xx.c [!MACH] (vm_offset_t, vm_size_t): Don't define types.

Add missing phystokv/kvtophys calls

2012-03-24T01:54:49Z

* i386/i386/vm_param.h [!MACH_XEN]: Do not include . * i386/i386at/model_dep.c (init_alloc_aligned): Use phystokv to compare physical memory addresses with kernel start, end, and symbol table. * i386/intel/pmap.c (pmap_enter): Use kvtophys to convert ptp pointer to pte entry. * linux/dev/init/main.c (alloc_contig_mem, linux_init): Use phystokv to convert allocated pages to virtual pointer. * linux/src/include/asm-i386/io.h: Include . (virt_to_phys): Call _kvtophys. (phys_to_virt): Call phystokv. * linux/src/include/linux/compatmac.h: Include . (ioremap): Use phys_to_virt to convert physical address to virtual pointer. (my_iounmap): Likewise. * linux/dev/include/asm-i386/page.h: Include . (PAGE_SHIFT, PAGE_SIZE, PAGE_MASK): Remove macros. * linux/src/drivers/scsi/ncr53c8xx.c (vm_size_t): Remove type. * linux/dev/glue/net.c: Include (device_write): Call phystokv to convert from physical page address to virtual pointer. * linux/dev/glue/block.c (alloc_buffer, free_buffer, rdwr_full): Likewise.

Change types holding cpu flags from int to long

2012-03-20T01:09:13Z

On amd64 the cpu flags is a 64-bit word, and long on 32-bit systems is 32-bit wide anyway. * linux/dev/glue/kmem.c (linux_kmalloc, linux_kfree, __get_free_pages, free_pages): Use unsigned long instead of unsigned. * linux/dev/include/asm-i386/system.h (__save_flags, __restore_flags): Likewise. * linux/dev/kernel/printk.c (printk): Likewise. * linux/src/drivers/scsi/advansys.c (DvcEnterCritical, DvcLeaveCritical, advansys_queuecommand, advansys_abort, advansys_reset, advansys_interrupt, interrupts_enabled, AdvISR): Likewise. * linux/src/drivers/scsi/aha152x.c (aha152x_intr): Likewise. * linux/src/drivers/scsi/aha1542.c (aha1542_intr_handle): Likewise. * linux/src/drivers/scsi/aic7xxx.c (aic7xxx_done_cmds_complete): Likewise. * linux/src/drivers/scsi/ultrastor.c (log_ultrastor_abort, ultrastor_queuecommand, ultrastor_abort): Likewise.

Fix format for string print

2012-02-19T01:32:19Z

* linux/src/drivers/scsi/aha1542.c (aha1542_setup): Use %s format for printing a mere string, not the string.

Fix format for string print

2012-02-19T01:17:21Z

* linux/src/drivers/scsi/advansys.c (asc_prt_line): Use %s format for printing a mere string, not the string.

Leave interrupts enabled in sym53c8xx driver

2011-10-09T23:01:37Z

The driver can work with them, and request_irq works fine with them. * linux/src/drivers/scsi/sym53c8xx.c (ncr_attach): Do not pass SA_INTERRUPT to request_irq().

Add sym53c8xx driver from linux 2.2

2011-10-08T20:07:08Z

This driver supports qemu's SCSI host device. Unfortunately it seems to be breaking the network device, so test with care. * linux/Makefrag.am (liblinux_a_SOURCES): Add linux/src/drivers/scsi/sym53c8xx{.c,_comm.h,.h,_defs.h} * linux/configfrag.ac: Add AC_Linux_DRIVER([sym53c8xx] to enable CONFIG_SCSI_SYM53C8XX. * linux/dev/glue/kmem.c (MEM_CHUNKS): Increase to 16. * linux/src/drivers/scsi/hosts.c [CONFIG_SCSI_SYM53C8XX]: Include "sym53c8xx.h". (builtin_scsi_hosts): include SYM53C8XX.
