2008-01-11[SCSI] aic94xx: update BIOS image from user space.Gilbert Wu
1. Create a file "update_bios" in sysfs to allow user to update bios from user space. 2. The BIOS image file can be downloaded from web site "http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300" and copy the BIOS image into /lib/firmware folder. 3. 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).

2008-01-11cache 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.

2008-01-10libata: don't normalize UNKNOWN to NONE after resetTejun Heo
After non-classifying reset, ehc->classes[] could contain ATA_DEV_UNKNOWN which used to be normalized to ATA_DEV_NONE for consistency. However, this causes unfortunate side effect for drivers which have non-classifying hardresets (e.g. sata_nv) by making hardreset report ATA_DEV_NONE for non-classifying resets and thus makes EH believe that the port is unoccupied and recovery can be skipped. The end result is that after a device is swapped with another one, the new device isn't attached after the old one is detached. This patch makes ata_eh_reset() not normalize UNKNOWN to NONE after non-classifying resets. This fixes the above problem. As UNKNOWN and NONE are handled differently by only EH hotplug logic, this doesn't cause other behavior changes.

It appears that gcc cannot guarantee 16-byte alignment in the kernel with __attribute__. The following report from Torben Viets shows a buffer that's only 8-byte aligned: > eneral protection fault: 0000 [#1] > Modules linked in: xt_TCPMSS xt_tcpmss iptable_mangle ipt_MASQUERADE > xt_tcpudp xt_mark xt_state iptable_nat nf_nat nf_conntrack_ipv4 > iptable_filter ip_tables x_tables pppoe pppox af_packet ppp_generic slhc > aes_i586 > CPU: 0 > EIP: 0060:[<c035b828>] Not tainted VLI > EFLAGS: 00010292 (2.6.23.12 #7) > EIP is at aes_crypt_copy+0x28/0x40 > eax: f7639ff0 ebx: f6c24050 ecx: 00000001 edx: f6c24030 > esi: f7e89dc8 edi: f7639ff0 ebp: 00010000 esp: f7e89dc8 Since the hardware must have 16-byte alignment, the following patch fixes this by open coding the alignment adjustment.
