The psi240i driver is still written for cmnd->request_buffer as a char pointer to actual data.

2008-01-11[SCSI] add DID_REQUEUE string to scsi_show_result host tableMike Christie
I was working on patches which add new transport error values, when I noticed that DID_REQUEUE was not in the hostbyte_table. I do not think there is any way to hit the code path where scsi_show_result is called and where you return DID_REQUEUE, because DID_REQUEUE causes scsi-ml to always requeue the command. However, for completeness and because I want to one day send a patch that tries to add new host bytes values, I am sending this patch.

The aic994xx will accept "update bios_file" and "verify bios_file" commands to perform update and verify BIOS image . For example: Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios" to update BIOS image from /lib/firmware/as483c01.ufi file into HBA's flash memory. Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios" to verify BIOS image between /lib/firmware/asc48c01.ufi file and HBA's flash memory. 4. Type "cat /sys/devices/.../update_bios" to view the status or result of updating BIOS.

2008-01-11ps3fb: fix deadlock on kexec()Jeremy Kerr
Since the introduction of the acquire_console_sem calls in 0333d83509c7d8496c8965b5ba9bc0c98e83c259, kexecing can cause the kernel to deadlock: ps3fb_shutdown() -> unregister_framebuffer() -> fb_notifier_call_chain(FB_EVENT_FB_UNBIND) -> fbcon_fb_unbind() -> unbind_con_driver() -> bind_con_driver() [ acquires console_sem ] -> fbcon_deinit() -> fbops->fb_release(newinfo, 0) -> ps3fb_release() -> ps3fb_sync() [ acquires console_sem ] This change avoids the deadlock by moving the acquire_console_sem() out of ps3fb_sync(), and puts it into the two other callsites, leaving ps3fb_release() to call ps3fb_sync() without the console semaphore. [Geert] - Corrected call sequence above - ps3fb_release() may be called with and without console_sem held. This is an inconsistency that should be fixed at the fb level, but for now, try to acquire console_sem in ps3fb_release(). I think it's safer to let ps3fb_release() try to acquire console_sem and not refresh the screen if it fails, than to call ps3fb_sync() without holding console_sem, as ps3fb_par may be modified at the same time, causing crashes or lockups. Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen when display flipping is disabled, which is an uncommon case (except during shutdown/kexec).

2008-01-11ps3fb: prevent use after free of fb_infoJeremy Kerr

2008-01-11cache invalidation error for buffered writeMassimo Cirillo
The bug causes corruptions of data read from flash. The original code performs cache invalidation from "adr" to "adr + len" in do_write_buffer(). Since len and adr could be updated in the code before invalidation - it causes improper setting of cache invalidation regions.

2008-01-11[MIPS] Malta: Fix software reset on big endianDmitri Vorobiev
I noticed that the commit f197465384bf7ef1af184c2ed1a4e268911a91e3 (MIPS Tech: Get rid of volatile in core code) broke the software reset functionality for MIPS Malta boards in big-endian mode. According to the MIPS Malta board user's manual, writing the magic 32-bit GORESET value into the SOFTRES register initiates board soft reset. My experimentation has shown that the endianness of the GORESET integer should thereby be the same as the endianness, which has been set for the CPU itself. The writew() function used to write the magic value in the code introduced by the commit mentioned above, however, swaps bytes for big-endian kernels and transfers 16 bits instead of 32. The patch below replaces the writew() function by the __raw_writel() routine, which leaves the byte order intact and transfers the whole MIPS machine word. Trivial code cleanup (replacing spaces by a tab and cutting oversized lines to make checkpatch.pl happy) is also included. The patch was tested using a Malta evaluation board running in both BE and LE modes. For both modes, software reset was fully functional after the change. P.S. I suspect that the same commit broke the "standby" functionality for MIPS Atlas boards. However, I did not touch the Atlas code as I don't have such board at my disposal and also because the linux-mips.org Web site claims that Atlas support is scheduled for removal.
